Guides: Hardiness Zone 3
Bletilla are deciduous terrestrial perennial orchids boasting attractive pleated, linear to lance-shaped leaves, and erect racemes of bell-shaped flowers in spring and summer. The delicate flowers vary in color from white to purple to yellow. Bletilla striata (Chinese Ground Orchid), Bletilla formosana Taiwan Ground Orchid), Bletilla ochracea (Chinese Butterfly Orchid) are 3 popular hardy species of orchids grown by gardeners in temperate climate areas. They grow from pseudobulbs that usually sit at ground level. A well established clump of these in flower is quite beautiful and rewarding.
Prized for its delightful fragrance, Syringa vulgaris (Common Lilac) is a mainstay of the spring landscape in northern and colder climates. Easy to grow, tough as nails, deer resistant and relatively free from major pests, Common Lilacs are one of the most effective flowering shrubs. Tailored to meet the needs of all gardens, this species counts 2000 cultivars.
Mostly native to the U.S. and Canada, Asclepias include over 100 species of evergreen or deciduous perennials adorned with clusters of small, interestingly shaped blooms that are irresistible to butterflies. Attractive and easy to grow, they shine in many perennial gardens and are a key component of butterfly gardens, cottage gardens, or prairies and meadows.
Attractive, Sea Holly plants (Eryngium) are striking ornamental perennials grown for their arresting, thistle-like, silvery or blue tinted flower heads adorned with a ruff of showy bracts. Blooming in summer and sometimes into fall, they are useful in rock gardens, coastal gardens and in borders where their steel blue flowers and foliage complement the vibrantly colored summer flowers.
Most water lilies typically need a minimum of six hours of direct sunlight in order to produce their spectacular blooms. However, some will flower in part shade with between 4-6 hours of sunlight daily. None grow in deep shade with less than 3 hours of sunlight each day.
There are about 20 rose species native to the United States. Despite their remarkable charms, they represent less than 2 percent of the rose market and seem to be overlooked by landscapers and gardeners. Although not as showy and spectacular as the European and Asian species and hybrids brought to the United States in the past centuries, we believe these native roses should have a place in today’s landscapes.
The Large Flowering Amaryllis group is the most popular group with single flowers up to 8-10 in (20-25 cm). Their cultivars belong to the Galaxy group. Each bulb usually produces 2-3 stems and 4-6 flowers per stem. These exquisite Amaryllis tend to grow up to 18-24 in. tall (45-60 cm). Depending on temperature, they bloom 6-10 weeks after planting.
Tulips, daffodils, hyacinths and crocus: these are the spring bloomers everyone knows. But there are hundreds of other, lesser-known beauties to plant in fall. Some are small and delicate, others tall and ungainly. All are fabulous. Wait till you see them!
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.
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.
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.
