Pretty soon, it will be time for our houseplants to leave their outdoor summer setting to return indoors.
It’s best to bring houseplants indoors in early September, before evening temperatures stay in the 50s, and definitely before we have a frost or freeze.
You want to make sure that what you bring indoors are the plants and not unwanted hitchhikers. Before moving plants indoors, give them a good shower. Use the showerhead nozzle on the hose and be sure to spray the undersides and tops of leaves. Pay special attention to where the leaves attach to the stem to make sure no tiny insects are hiding in any crevices. Give the soil a good soaking, too.
Keep the plants you are moving indoors separated for a week or so from those that stayed inside, if you are worried about possible insect or disease contamination.
Continue to pick tomatoes, peppers, squash and other vegetables as they ripen. Harvesting keeps production strong for the next several week. Preserve what you have too much of, or share it with family, friends, neighbors, soup kitchen or food pantry. Keep watering vegetable plants, too. As you pull out warm-season crops, replace them with lettuce, spinach, chard and other greens.
Tidy up any summer plants in pots to keep them looking good until it’s time to change them out for a fall scheme. Make sure to keep the pots watered and plants fertilized. Pull out what has lost its usefulness.

I’m not an okra fan, except for the flowers, which are beautiful and reveal their ties to the hibiscus family. And the fruit is attractive, whether it’s green or red. All-America Selections recently announced Candle Fire okra is a 2017 winner. Judges deemed Candle Fire’s fruit a brighter red than other red fruited varieties on the market, and the pods are rounded without ribs. Harvest is 60 days from sowing seed or 30 days from a transplant. Look for it in spring mail order catalogs and online seed merchants.

Begonias are an under appreciated plant. There are so many types, forms and sizes that there’s one for every pot of annuals or in-ground planting scheme. Some thrive, even flower, in deep shade and others burst into bloom in full sun. Leaves can be glossy, bumpy, variegated, patterned, deeply veined, one color on top and another color on the bottom, smooth and fuzzy.
There’s even one that’s winter hardy in our area. Begonia grandis has pink or white flowers in August, but like most begonias, the real beauty is in the leaves—green with red veins on top and greenish-purple on the bottom.

Most of the begonias we grow though are tropical, and there are a bunch of them. Some of the new hybrids, such as Dragon Wing, Baby Wing, Big, Bada Bing and Bada Boom, are extremely showy with large flowers. These plants tend to be more upright with strong stems. Some have large, glossy, bright green leaves and some have smaller, dark green foliage. These hybrids have leaves that are green or bronze with flowers that are red, pink or white. They do well in full sun to part shade.
The Begonia boliviensis species also can take the sun and tolerates shade. It has a more relaxed, cascading habit and trumpet- or star-like flowers. Santa Cruz Sunset and Bonfire are two popular varieties in this group.
Probably the most common are the wax-leaf or bedding begonias, with the Cocktail series the most readily available.

One of my favorites is the Rieger begonia (B. x hiemalis), which has tight, rosette-like flowers in pastels and red. This begonia is very shade tolerant and if deadheaded, retains a clean look throughout the summer. Rieger begonias are also popular houseplants.
Another popular houseplant is the Rex begonia. Over the last few years, these exotic hybrids have escaped their indoor environment to add beauty, texture, unusual blooms and forms in shady outdoor settings. This is the group of plants that has such incredible foliage that flowers are an extra. ‘Escargot’ describes the swirly pattern in the leaves of one Rex begonia.

My least favorite is tuberous begonia (B. x tuberhybrida), a truly beautiful plant, but one that I find too challenging because the stems are brittle and subject to rotting off.

The popularity of begonias is on the upswing because they are so versatile, something the National Garden Bureau, a trade association of plant breeders, decided to acknowledge in 2016 as the Year of Begonia.
The dog days of summer are upon us and what better way to enjoy this little bit of leisure time than with a cocktail in the garden.
First up, set the stage for the evening, said former Hoosier C.L. Fornari, in her book The Cocktail Hour Garden (2016, St. Lynn’s Press, $19.95, hardcover). Is the landscape past it prime? Have the plants seen better days? Remember that plants are like people, in that they have lifespans, and some age better than others. When shrubs, trees or perennials stop earning their keep because they bring you more worry than joy, yank them out and replace them with something else. Ask yourself: What do the plants bring to the party?
“I want readers to see their yards and gardens from a new, celebratory perspective. My focus here is on creating landscapes for evening relaxation, renewal and entertaining, so the party metaphor is fitting,” wrote Fornari, who gardens at Poison Ivy Acres on Cape Cod.
When sitting outdoors in the evening, think about fragrance and brightness. White and silver are the colors of the hour because they glow as nighttime falls. Dusty miller (Seneceo cineraria) , lamb’s ear (Stachys bizantina), and licorice plant (Helichrysum petiolare) are a few fuzzy, silver-leaf selections. Four o’clock (Mirabilis jalapa), flowering tobacco (Nicotiana sylvestris) and moonflower (Datura spp.) perfume the air.
In the late afternoon and early evening sun, hummingbird moths and hummingbirds will join you, visiting flowers to imbibe on nectar. Set them up with hummingbird mint (Agastache spp.), cardinal flower (Lobelia cardinalis), sage (Salvia spp.), and bee balm (Monarda spp.) and they’ll come calling.
Here’s a Fornari recipe to sip while watching the birds and enjoying the cocktail hour.
Basil Margarita (for each drink)
5 or 6 large basil leaves
1 ounce fresh lime juice
1 ounce agave nectar
2 ounces blue agave tequila
Lime and basil for garnish
Salt for rim (optional)
Rub the rim of the glass with a lime wedge first and press the salt against the edge. Muddle basil a bit in a Mason jar or cocktail shaker, add lime juice and agave nectar, and muddle again. Add tequila and ice cubes. Shake well. Strain into the glass and garnish with the basil and lime.

Nestled next to DNR on the northside of the Indiana State Fairgrounds you’ll find the Purdue Extension Marion County Demonstration Garden. Hundreds of All-America Selections annuals perennials, vegetables, and herbs are on display. Visitors also can check out tomato caging techniques, raised bed options, and environmentally sensitive ways control insect and disease.
Surfinia Heartbeat petunia from Suntory. (C) Jo Ellen Meyers Sharp
A few weeks ago, I made my annual trek to Cultivate, the country’s largest horticulture trade show in Columbus, Ohio. It’s where about 10,000 people go to see new plants, pots, tools, greenhouses, planting machines and more, at 1,000 booths in the Greater Columbus Convention Center.
The trade show is truly overwhelming, so it helps to have a plan. Mine is always to visit with the folks who send me items to trial. Then, I’m on the lookout for cool plants, something different or much improved on what’s available. Some years there are real stunners.
Surfinia ‘Heartbeat’, a trailing petunia from Suntory, was displayed everywhere, on banners, in pots and in faux garden settings. It’s easy to see why, because it is cute and interesting – pink hearts form where the petals fuse together.

This annual, with a slightly mounded habit, gets about 12 inches tall, with a 12-18 inch spread. It’s perfect for hanging baskets, window boxes and other containers in sunny locations. With flowers about 1 1/2-inches wide, plant ‘Heartbeat’ where you can appreciate its novel look.
Among the perennials, I really liked ‘Blue Frills’ Stokes’ aster, a cultivar of the eastern U.S. native plant (Stokesia laevis). ‘Blue Frills’, introduced by Blooms of Bressingham, has 2 ½-3 inch wide, blue-violet flowers with dark centers. The plant will get 18-24 inches tall and blooms for most of the summer into fall. Stokes aster prefers full sun and slightly more wet than dry soil.

In the edible landscape category, two plants caught my eye. Balsamic Blooms basil (Ocimum x ‘Dbasbloom’) will be a 2017 offering in the HGTV Home Plant collection. Usually we don’t want herbs to bloom because it can diminish the taste, but this basil was bred to bloom, yet retain its flavor. Just like other basils, Balsamic Blooms’ 3-inch wide flower is edible, too. The plant will get 12-18 inches tall.

Hort Couture Plant’s Edibliss Heavy Metal Chinese cabbage has beautiful, puckered, glossy dark purple, oval leaves with a touch of green at the center. In cooler temperatures, the foliage, streaked with bright white midribs, takes on a reddish hue.
Look for these plants next year in garden centers or look for seeds in online or mail-order retailers. Try something new.
Dramm’s brass hose swivel reduces kinked and twisted hoses when watering the garden. (C) Jo Ellen Meyers Sharp
When I worked fulltime at a garden center, one of my jobs was watering the plants. It was kind of a mindless, peaceful, relaxing job, cursed by hauling heavy hoses that kinked and got twisted. Of course, kinked, twisted hoses are not just a workplace problem. They are the same at home, and I’ve always said I’d pay good money for a hose that does not kink or twist.
Last summer, at the suggestion of several garden writer colleagues, I purchased two, pricey, 75-foot Flexzilla garden hoses, touted for their light weight and resistance to kinking and twisting. The hoses also were rated safe for drinking water. Most hoses are not approved for drinking water because they are made with lead and other toxins. The Flexzillas passed the lightweight test, but they failed the no-twist, no-kink test.
Last fall, Dramm gave garden writers a Brass Hose Swivel, which goes between the hose and an attachment, such as Dramm’s One Touch RainWand, one of my favorite watering tools. This 2-inch piece of solid brass does exactly what it promises – keeps a hose from twisting, which pretty much eliminates kinks. This swivel is a must-have for anyone who does a lot of watering, including garden centers. A lightweight hose that doesn’t twist puts the pleasure back into watering.

This year, the weeds have been particularly prolific. My favorite tool for weeding is Corona’s 60-inch oscillating hoe, sometimes called a stirrup or scuffle hoe. A 6-inch blade slices off weeds at or just below the soil line with a push and pull. You can’t really go wrong with any tool from Corona, including another favorite, its 7-inch Razor Tooth Pruning Saw. This folding saw makes fast work of pruning thicker branches.
You can’t go wrong with tools from Fiskars, either. I especially like Fiskars’ Pruning Stik. At 5-foot long, this is the best tool for reaching up into trees or down into shrubs to remove branches up to 1 ¼ inch diameter. It is rope-free, so you can control the pruner with two hands. A chain-driven gear enables cuts to be clean and precise.

This is the second Pruning Stik I’ve had. The first one broke after about 10 years. I called Fiskars customer service and, in accordance with a lifetime warranty, the company shipped me a new one. You can’t beat that.

Let’s pretend we’re in a drone, buzzing some Indianapolis-area, midsummer gardens to see what’s going on. Immediately observable: Plants seem bigger and more lush than normal.
“In general, all plants have shot up taller than usual, due to the heavy rains. This is particularly noticeable with woody perennials. It’s like they’re on steroids,” said Debra Boyer, a Marion County Master Gardener in Fountain Square.
“As for annuals, my wholesaler was out of Dragon Wing begonias so I purchased Big begonias from a retailer. They are striking in the container planting with ‘Irene’ Lantana and ‘Black Magic’ Colocasia. In this case, the alternative worked out better than what I planned,” said Boyer, a facility manager.
Also on the city’s southside, Sue Nord Peiffer praises her 20-year-old, native Hydrangea arborescens. “My shrub measures 6 foot wide by 4 foot high and has rarely been pruned. It may not be as showy or fancy as the hybrids, but it has about 100 blooms.”
The hydrangea teems with pollinators on sunny days and takes virtually no effort, but water during dry periods, said Peiffer, manager of the greenhouse at the Indianapolis Museum of Art. “I grow it on the north side of my house in fairly deep shade. I love this plant.”
In Avalon Hills on the city’s northeast side, Jane Lommel, past president of Binford Redevelopment and Growth, has hundreds of hostas in her woodland garden. “This year, they are uniformly much taller and wider than usual. And the blooms are bigger and fuller than in years past.” She’ll soon be adding ‘Claude Shride’, a bright, dark red Martagon lily from Indianapolis’ Soule’s Gardens, for more color among the hostas.
Hendricks County Master Gardener Colletta Kosiba has marveled at the vigor of all plants. The most impressive are the hostas, with leaves at least one-third bigger than ever before, she said. “The second most impressive are the butterfly weed plants. It’s a very good year for them, too.”
Greenwood-based freelance writer and editor, Brian D. Smith, who dubs himself Mr. Tomato Head, planted his usual combination of heirloom and tasty hybrids. “It’s a given that the hybrids grow fast, but this year my heirlooms – ‘Pink Brandywine’, ‘Cherokee Purple’, ‘Great White’ – are reaching for the sky at nearly the same rate as the hybrids. And nearly every plant has already begun kicking out at least one or two ‘greenies.’ Apparently they like the weather we’ve had since late May, although I can’t help thinking they’d enjoy a stretch of mid-80s temperatures more than the 90s.”
The early season warm temps and plentiful rain have benefitted my landscape, too, in many of the ways described by the other gardeners. Most notably, though, I have towering thistle, lamb’s quarter, fleabane and other weeds where I’ve never had them before. Mother Nature sometimes delivers the good with the bad.
Glory-of-the-snow (Chionodoxa) is an early bloomer with starry, lavender-blue flowers that shade to white in the center. An excellent naturalizer when planted in soil that drains well, it is suited to growing in garden beds, lawns, woodland areas, and rock gardens. Left undisturbed in sun or light shade, glory-of-the-snow often self-sows, eventually forming a dense carpet of blooms. They are deer and rodent resistant. Photo courtesy Colorblends.com
Yes, I know it’s still July, but now is a good time to be thinking about next spring’s bulbs. Why is that? Because now is the time to order bulbs from online and mail-order retailers.
Of course, local garden centers will have perfectly good bulbs in a few weeks, but for a broader selection of colors and more unusual blooms, online or mail order is the way to go. The bulbs are shipped in fall when it’s time to plant them. Here are some tips.
Bloom time. Tulips, daffodils, and alliums bloom early, mid or late season, depending on the cultivar. Gardeners with shadier or woodland landscape should seek out early season bulbs because they will bloom before the trees and shrubs leaf out.
Several minor bulbs, which include glory-of-the-snow (Chionodoxa spp.), squill (Scilla siberica), tommies crocus (C. tommasinianus), not only bloom early, they are perfect for naturalizing as floral carpets under trees and shrubs or in the lawn.
Indianapolis gardener Carol Michel (maydreamsgardens.com) recently told me she’s ordered 500 more glory-of-the-snow to add to the thousand she’s already planted in her lawn. These are especially for lawn areas because the foliage ripens and replenishes the bulbs under ground before the grass has to be mowed.
Deer and squirrel. If deer like to dine in your garden, plant daffodils (Narcissus spp.), which are toxic to animals and humans. Deer do not eat daffodils, and in our climate, these are among the most reliable spring bulbs to plant. Squirrels also tend not to bother daffodils.
Tulips (Tulipa spp.), on the other hand, are like lollipops for deer, which eat the tops. Squirrels like them, too, and eat the bulbs. You can protect tulips with animal repellants, such as Plantskydd, Animal Stopper or Liquid Fence. (At least we don’t have to contend with Moose and Squirrel!)
Colors. Go with what you like. Some gardeners plant a new color scheme each fall, especially with tulips, which tend to decline year after year. Replenish the look by buying and planting a few each year. Some companies, such as Colorblends.com and Longfield-Gardens.com, mix the colors for you. Other favorite places to look for bulbs: oldhousegardens.com, brentandbeckysbulbs.com and vanengelen.com.
Size counts. Smaller or lower grade bulbs are fine for naturalizing, but for the best seasonal show, go with the largest you can find, especially tulips. Bulbs are graded by their size, and with daffodils, the number of noses, or growth points they have. Don’t buy bulbs that are soft or moldy.
Proven Winners’ Sugar Shack buttonbush is a smaller introduction of a very large shrub. Photo courtesy Provenwinners.com
There are some shrubs that I’ve lusted after for several years, such as a buttonbush and witch hazel.
The drawback has been that these plants are huge, 8-12 feet tall and wide, or larger. I eventually ripped out the beautiful ‘Limelight’ hydrangea (H. paniculata) because at 8 feet tall and wide, it just got too big for my landscape and was out of scale for the house.
A couple years ago, I got Sugar Shack buttonbush (Cephalanthus occidentalis), a native cultivar from Proven Winners to trial, and it’s a keeper. It was less than a foot tall when I planted it, encased in a tomato cage to protect the young shrub from dogs’ paws. This year, Sugar Shack is about 30 inches tall and budded up, ready to bloom. At maturity, it will be 3-4 feet tall and wide, about half the size of the straight species.
The deciduous shrub’s leaves are glossy medium green. It blooms fragrant, button-like, ball-shaped flowers in early summer, which are appreciated by nectar-loving butterflies, bees and other insects. Birds like the seed heads, which turn bright red in fall.
Buttonbush prefers full to part sun and tolerates a moist location, so it would work in a swale or rain garden. Mine seems to be thriving, though, in regular garden soil. Buttonbush blooms on current season growth, so it can be pruned in late winter or early spring, if needed. It also is deer resistant.

I’m also enthused about ‘Sun King’ golden Japanese spikenard (Aralia cordata), which enlivens the shadier areas of the landscape.
This perennial was introduced in the U.S. by well-known plantsman Barry Yinger. It’s bright gold leaves form on arched branches about 3 feet long. There seems to be a pretty wide swing on the size of this plant, with sources pegging it in the 3 or 6 foot tall and wide range. I’m hoping for the smaller size.
Two-foot tall spikes of ball-like flowers emerge through the foliage in midsummer. When the flowers fall, reddish purple berries form, a treat for birds. This plant does best in well-drained, moist soil. It will likely lose its golden hue if grown in too much shade. ‘Sun King’ also is deer resistant.

Just like slow food, there’s a slow flowers movement that promotes growers and florists who embrace and market blooms and branches grown in their area, region or country, as well as serve as a resource for consumers.
SlowFlowers.com has declared June 28 to July 4 American Flowers Week as a way to encourage all of us to cut or buy a locally grown bouquet for our holiday celebrations.
Begun in 2015, the goal is to engage the public, policymakers and the media in a conversation about the origins of their flowers, said Debra Prinzing, founder of American Flowers Week. About 20 percent of flowers sold in the U.S. are grown here.
“The Fourth of July is a perfect time to support domestic U.S. flower farms by choosing local, American-grown bouquets. It’s also the time of the year when local and seasonal cut flowers are being grown and harvested in all 50 states,” said Prinzing, who founded SlowFlowers.com in 2014.
On the east side, Indy Urban Acres devotes 1 ½- of its 9 ½-acre organic operation to growing mostly annuals, said Lauren Brown, cut flower manager of the not-for-profit. Indy Urban Acres is an initiative of Indy Parks Foundation and is on park land. Proceeds from cut flower sales support the food-growing operation, where all produce is donated to area food banks, soup kitchens and other groups that feed the hungry.
The flower-growing operation started with annuals in 2014. Brown has been planting perennials, such as coneflower, campanula and black-eyed Susan, to add to the selection. She sells her cut flowers at the Market at Hague at Lawrence North High School, and for weddings and special events. Consumers like that the flowers are organic and grown locally, she said.

Well-known florist, event planner and peony grower, Pam Parker, owner of JP Parker Flowers in Indianapolis and Franklin, also grows sunflowers and zinnias, staples of summer cut flowers on about 14 acres on farms in Shelby and Johnson counties. She’s added ornamental corn, celosia, hanging amaranth and marigolds to the mix, and sells her flowers at Broad Ripple, Carmel and Franklin farmers markets.
Parker said many of today’s brides are interested in what she calls “American garden” bouquets, loose arrangements of field flowers.

In northern Marion County, Molly & Myrtle Indianapolis Vintage Weddings uses cut flowers as part of its event planning services, which includes curated period furnishings and architectural elements. Owner Amy Beausir farms just under an acre, growing annuals, perennials, and greenery, which she sells at Abundant Life Market at 82nd Street and Hague Road.
She’s been in the cut flower business for seven years, and she includes shrubs, such as blueberry, viburnum and magnolia, for year-round arrangements. When flowers are cut the day they are sold or the day before, they last much longer in arrangements, Beausir said. “Slow flowers have an authenticity, are habitat friendly and they don’t look like they are grown by a corporation.”

Even though summer has just arrived, there are a few things we can do in the garden to help extend the season for our plants.
First up, give annuals and vegetables a dose of fertilizer. For annuals in containers or in the ground, apply a water-soluble fertilizer. For the vegetable bed, I prefer a granular fertilizer applied as a side dressing, where it’s lightly worked into the soil. Or, you can ring the plants with the fertilizer. Either way, water it in. Always read and follow the label directions.
Harvest green beans, tomatoes, squash and other vegetables as they ripen. This encourages the plants to keep producing. If there’s no rain, be sure to water vegetable plants about 1 inch a week, which also supports good production. Target the water to soil around the base of the plants rather than applying it overhead.
For herbs, harvest them as they grow. Once an herb starts to flower, it frequently loses flavor. You can eat the blossoms of mint, basil, lavender and several other herbs.

For perennials, remove the spent flowers. Called deadheading, it tricks the plants into developing a few more flower buds along side shoots to prolong the show. Remove the seed heads on spring-blooming perennials, such as columbine, iris and peony.
If lilac, viburnum or other spring-blooming shrubs need to be pruned, do so as soon as possible. Pruning any later in summer or fall will remove next year’s blooms. Remember that pruning should always be done for a purpose, such as removing an errant branch, dead stem, to boost fruit or flower production or rein in its size. Remember to keep the top of the shrub slightly more narrow than the base of the plant. If the top is wider, it shades out the base, causing it to look sparse or bare.
As the temps rise, mowing duties are reduced, unless your lawn is irrigated. Mow to keep the lawn about 3 inches tall, which crowds out weeds and keeps grass roots cool.
And, if we go three weeks with no rain, water perennials, shrubs and trees. Healthy lawns can usually go six weeks without supplemental watering.
