Pretty Tulips that Come Back Every Year

Many tulips are not strongly perennial and their floral display tends to decline from season to season. They bloom well the first year, but then peter out after a couple of years. But if you select the right tulip varieties, plant them in the right spot and provide the proper care, you can be rewarded with a magnificent spring display year after year.

Naturalizing Bulbs In The Lawn

Naturalizing bulbs is a terrific way to brighten up lawns. A surprisingly large number of perennial bulbs do well in grass, such as snowdrops (Galanthus), crocuses (Crocus), squills (Scilla), checkered lilies (Fritillaria meleagris) and plenty others charming bulbs. Left undisturbed in the ground, they will emerge again every spring, but will also gently multiply as long as they receive the right light conditions and are planted in soil with the proper drainage.

Helleborus (Hellebores)

There are 17 Hellebore species. Most are native to the mountainous regions of Europe, especially the Balkan region of the former Yugoslavia, south along the eastern Adriatic to Greece and Turkey. Many of the species have been interbred, producing countless hybrid Hellebores in a rich array of colors and forms.

Erythronium (Dog Tooth Violets)

A member of the Lily family, Erythronium (Dog Tooth Violet) are charming bulbous perennials grown for their nodding, lily-shaped flowers adorned with gracefully reflexed petals in spring. Equally attractive is their foliage of elliptic leaves, often copiously marbled with purple-bronze.

Bulbs That Thrive Under Trees

Flowering bulbs look appealing when planted under garden trees. However, planting any bulbs beneath trees is not always successful because of the dense shade cast by the trees, the competition with their roots and the lack of moisture under these trees. If a tree competes with bulbs for light, water or nutrients, the tree always wins.
