The bright pink or white flowers begin in August and continue into fall. However, contrary to its common name, this plant is not very obedient and will wander in the garden. Plants prefer full sun and are tolerant of diverse soil types. There are several ornamental grasses that flower in late summer and into fall. After these 2 to 8 foot perennials die in late fall, their tall tan-colored leaves and plumes remain standing and blow gracefully in the winter winds.
Most ornamental grasses prefer full sun and well-drained soils.
Monkshood is a stately 3 to 5 foot perennial with blue, lavender, or white flowers beginning in August. The flowers resemble a monks hood hence the common name. This perennial prefers a moist, fertile, well-drained soil in part shade. Since all parts of monkshood are poisonous, individuals with small children may want to plant other perennials. Toadlily has an unusual white flower often marked with tiny purple spots.
