Plants for landscaping: Bulbs

As tempting as it may be to take some time off and bask in the September sun, gardeners know that part of their attention needs to stay actively focused on next spring. Bulbs that can be expected to perform well next year should be fed this fall. And October is the right time to plant bulbs, whether as replacements for old ones that no longer bloom well or as new displays.

Gardeners use bulbs in a variety of ways. Large tulips or daffodils might take the spotlight in a stand-alone burst of spring color. Woodland gardeners may choose to naturalize daffodils. Perennial borders offer spots for bulbs where the yellowing foliage will be camouflaged by subsequent blooms. Rock gardens are excellent choices for small bulbs. The only sure rules are to avoid lining up bulbs in a stiff row and to plant at least three feet away from the house foundation so as not to interfere with the necessary chilling process.

Bulbs offer such variety that fresh design possibilities emerge every year. One designer has developed a stunning all-blue under-planting for a line of deciduous trees. Plenty of sun shines through the bare branches while a succession of small bulbs blooms. Try combining the following for 6-8 weeks of beauty: Grecian windflower (Anemone blanda); Glory-of-the-snow (Chiondoxa luciliae); Grape hyacinth (Muscari ?Valerie Finnis?); Siberian squill (Scilla siberica); Woodland crocus (C. tommasinianus); Grape hyacinth (M. latifolium).

While some of these small bulbs may sound exotic, they can be readily obtained from companies that specialize in bulbs, and they are dependable bloomers. Choose a site with good drainage, and try to plant when the soil is somewhat moist. Most small bulbs like a planting depth of 4-5 inches. Top the bed with a thin layer of compost and water well.

One under-used bulb that can make a real statement in the perennial border is allium. The globe form and range of heights and colors make this a terrific complement to other late-spring flowers. A white such as A. stipitatum ?Mount Everest? or a blue such as ?Pinball Wizard? guarantees drama.

While it is great fun to try something new, we all have old favorites as well. Nothing lifts my spirits more than catching a glimpse of a bee savoring the nectar from an early purple or yellow crocus. I try to find an additional spot every year for another clump close to a pathway or door.

Right now: This is a great time to divide perennials or to transplant those that haven?t been happy in their current spots.
