You know that gap between spring and summer, when there’s nothing blooming in the garden? It’s after the spring bulbs, columbine (Aquilegia) and Iris have bloomed but before coneflowers (Echinacea) and bee balm (Monarda) come on.
What’s missing are the bridge flowers, said Brent Heath, co-owner of Brent and Becky’s Bulbs, who will be in town for several speaking engagements and a hands-on workshop.
Gardeners just are not as familiar with them as they are the big three, tulips, daffodils and hyacinths, said Heath, who with his wife, Becky Heath, wrote Daffodils for American Gardens and Tulips for North American Gardens.
Most bulbs prefer it more dry than wet.
“Most bulbs like to sleep in dry beds,” he said during a telephone interview. On his recommended list for fall planting: Allium, Calochortus, Camassia, Dichelostemma, Dracunculus, Dutch Iris, Eremurus, Nectaroscordum and Triteleia.
Plant these bulbs in full sun and well-drained soil. Many are hardy here, but some are not, so check a bulb’s hardiness. As with all bulbs, once the flowers are done, allow the foliage to turn yellow or brown before removing it. I have grown some of these and they do, indeed, bridge the season. They also are terrific cut flowers. Here are few of my favorite late-spring, early summer bulbs.
Foxtail lilies (Eremurus) get 3-4 feet tall with spikes of yellow, orange, white or pinkish flowers. Plant in full sun, hardy to USDA Zone 5. Foxtail lilies are good cut flowers.
Indian hyacinth (Camassia) is a North American native plant that has blue or white star-like flowers atop 30-inch tall plants. I have two patches of camassia and it’s gorgeous, but if the weather heat up, these start to look a little bedraggled pretty quickly. Plant in full sun. Camassia is fully hardy throughout Indiana.
Allium atropurpureum and A. giganteum show up just when you think the spring bulb show is over. These ornamental onions have tall stalks topped with balls of blooms. Hardy in Indiana, but grow them in full sun and well-drained soil.
