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.
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.
More and more popular, the Cybister Amaryllis are truly spectacular with their exotic, orchid-like flowers. They feature long, ribbon-like, spidery petals and splashes of bright color such as deep reds, soft green, copper, dark pink, creamy white and burgundy. They are unlike any other Amaryllis group and their cultivars belong to the Spider group.
About 80% of orchids are natives of tropical latitudes, but a surprising number of terrestrial orchids are hardy, some even able to fearlessly withstand temperatures below -22°F (-30°C). With hardiness zones ranging from zone 2 to zone 9, they add an unexpected touch of exoticism in the landscape with their vibrant colors and long-lived blossoms.
Lady’s slipper orchids are among the most desired of all hardy orchids. Often colorful and striking, these rhizomatous perennials have a distinctive inflated pouch or modified lip (labellum) that resembles a slipper or shoe. The slipper can be as large as a chicken egg or quite small depending on the species. Cypripedium is a genus of terrestrial orchids in the Orchidaceae family. It includes about 50 species, most of them quite hardy, which can be found in America, Europe, and Asia.
Considered as one of the most colorful of all ground covers, Phlox subulata (Creeping Phlox) is a popular evergreen perennial with masses of delicate pink, magenta, purple-blue or white flowers in mid to late spring. They bloom so profusely that they literally blanket the dark green, needle-like foliage.
From a fragrance standpoint, not all sweet peas are equal. Some exude a faint scent, others are well scented, and some are intensely fragrant. According to researchers, the fragrance of sweet peas is determined by six major components and 12 minor ones. This is the combination of these major ingredients with the minor ones, which grants sweet peas their delightful perfume.
Native to the Mediterranean region, Lathyrus odoratus (Sweet Pea) is a bushy or climbing annual noted for the delicious scent of its lovely flowers.
