Flowered perennials are blossoming plants that bloom year after year. These flowers will give you a big return on your initial investment if you care for them properly. Perennials that bloom have specific needs that must be met, or they may not develop flowers at all. Some need exposure to full sunlight. Others need shelter from the hot afternoon sun or their petals and leaves will be scorched. These perennials should be planted in shady areas.
Monkshood (Aconitum) is a tall, regal plant that thrives in shady areas. The plant prefers moist, well-draining soil. Unlike many shade perennials, monkshood, which can reach heights of 2 feet, blooms in the fall with blue to purple flowers that look similar to those of the snapdragon. This makes it an excellent choice for rounding out a shade garden.
Old-Fashioned Bleeding Heart
This flowered perennial (Dicentra spectabilis) is spring-blooming and can grow up to 3 feet tall. It is excellent for deep shade areas under trees and other areas that are in deep shade. The flowers are pink, heart-shaped and dangle gracefully from long stems. The old-fashioned bleeding heart occasionally goes dormant in the heat of the summer. For that reason, it should be planted with other, summer-blooming plants.
The toad lily (Tricyrtis) is also a fall-blooming perennial. The flowers are graceful and look somewhat like miniature orchids. The toad lily thrives in rich, moist soil that does not collect standing water. This plant is a spreading perennial, which makes it an excellent choice for ground cover in shady areas.
Unlike many shade perennials, epimedium will grow in dry soil, such as that under trees. This short, flowering plant only grows to a height of 12 inches and works well as a ground cover. Epimedium blooms in the spring with red or yellow flowers surrounded by green heart-shaped leaves. In the fall, those leaves turn bright red, adding a splash of vibrant color to the dark corners of your garden.
Lily of the Valley
This is a classic, popular perennial. Lily of the valley has a fragile look about it, with small, delicate bell-shaped flowers, but the plant is actually quite hardy. This flower will thrive even in the deepest shade. Lily of the valley can even withstand full sun in cool climates. Hot sun, however, will scorch the plant's wide leaves. Lily of the valley spreads rapidly.
