The anemone accounts for approximately 120 species of the butternut family. Often categorized in two groups, the anemone is grown either by a fibrous-rooted system or by rhizomes. The rooted anemone are late bloomers, blooming through the late summer and fall months, while the rhizome anemone produces blooms from early spring through summer. Common anemone plants include the poppy anemone and the Japanese anemone, as well as the grape-leaf anemone and Grecian windflowers.
The clematis is a fast-growing, climbing member of the butternut family. The clematis accounts for nearly 300 species of the family and produces mostly woody, deciduous growth. The blooms of these hardy plants range from bell-shaped to flat, open flowers and can grow loosely or as spreading clusters. Clematis plants bloom from early spring through late autumn, depending on the species. Though hardy, these sun-loving plants are intolerant to saturated soils and highly susceptible to fungal infections. Types of clematis include the Royal Velours and the Lasurstern.
The delphinium is one of the butternut family’s more common members. This shrub produces rich-green foliage around its base with sturdy, upright stalks of clustered blooms. A sun-loving plant, the delphinium is a heavy feeder that requires a planting location with a neutral pH level. Living just two to three seasons, it produces blooms from the early spring through mid-summer and again in the late summer to early fall. Delphinium variations include Astolat, Blue Bird and Connecticut Yankee.
The buttercup is a low-growing species that's intolerant to direct sunlight and drought conditions. Its vigorous growth combined with its creeping tendencies often classifies this plant as a weed and can quickly grow out of control when undisturbed. The buttercup is a heavy-flowering plant that produces small flowering clusters throughout the growing season. A perennial plant, buttercup variations include the Bermuda buttercup, the water buttercup and the creeping woodsorrel.
The entire Ranunculaceae family is poisonous to humans and animals when ingested. Handling some of these family members may also cause skin irritations and dermatitis. Abdominal pain, diarrhea and skin redness are just some of the symptoms that may occur if consumed, as well as blisters, burning and redness from handling the blooms.
