You Can Grow That! March 2013: Geraniums

Vining geraniums, such as 'Pink Blizzard', are an under used plant for hanging baskets in summer. Photo courtesy Fischer.
Sometimes I think we’re plant snobs.
Geraniums (Pelargonium) seem to be at the bottom of the wish list for many gardeners because, well, they are geraniums — ordinary, old fashion, boring. Throw in reliable, easy and rewarding and you wonder why they are shunned.
For the common geranium, sometimes called zonal, you can buy plants grown from seed or made from cuttings. I opt for the more expensive cutting geraniums because they are so much showier that their seed-grown siblings. Seed geranium flowers are loose and a bit spindly, but work well in a mass planting.
Zonal geraniums are tough and do fine in full to part sun. Drought tolerant, they prefer good drainage, whether planted in the ground or in containers. Water when the first inch of soil feels dry to the touch.
Remove spent flowers, called deadheading, to keep geraniums blooming. They do best with regular applications of a balanced liquid fertilizer. Follow the label directions.
One of the best plants for containers is the under used ivy or vining geranium (P. peltatum). This plant has waxy leaves and the flowers tend to be a bit looser than zonals. Vining geraniums do best in part shade. They tolerate full sun.
Martha Washington geraniums (P. x domesticum), with their large, frequently frilly flowers, are popular in spring here in Indiana, but they tend to wimp out when it starts to heat up.
Scented geraniums are used as herbs and for their oils. Their foliage is aromatic, ranging in scents from rose, peppermint, apple, lemon and more. These do not have showy flowers. Plant where you brush against their leaves when you walk.
There’s also are many true geraniums (Geranium), which is winter hardy in Indiana. ‘Rozanne’, ‘Wargrave Pink’ and ‘Johnson’s Blue’ are popular cultivars.







I have been looking for the scented geraniums at garden centers around here but have only found the ordinary red white and pink geraniums. I did however discovered Geranium Molle in my garden. It just appeared!. I have used it as a cut flower and placed it in the bouquet which you can see in my sweet peas article. I think that Geraniums are underrated as well and that garden centers should sell different varieties.
Laila — you need to look in the herb sections. We have them at Sullivan’s at 71st and Keystone, but they usually come in in June. You also might check Dammann’s.
Thanks for the tip. Unfortunately I can’t import seeds from the US so I need to figure out where to find the scented geraniums here in Europe. I will start as you suggested in the herb section!
Plus, pelargoniums are an effective Japanese beetle control. Apparently, the beetles get stoned on the geranium, which paralyzes them for about 24 hours, making them a cinch to pick up and drown. The white ones have worked best for me. http://www.ars.usda.gov/is/pr/2010/100308.htm
