Adding color to shady spaces can sometimes be a challenge, but with this native wildflower the task is an easy one. Yellow Trillium, or Trillium luteum, features sunshine-yellow flowers with three petals amid stylish mottled, mid green leaves. It grows only 6-12" tall, making it a natural for tucking into the space between evergreen shrubs, under deciduous trees or at the front of a darkened border. Perfect for wooded sites and rock gardens. A native wildflower to the U.S., Yellow Trillium can often be found along trails in state parks during the early weeks of spring. Butterflies love this sunny little perennial, too.

Moist, well-drained, deeply organic soil is best.

Watering Requirements :
Keep soil moist in the spring-early summer. Plants may go dormant prematurely if the soil dries out and this has a negative effect on flowering next year.

When grown in organically rich soil, fertilizing is normally not needed. To promote flowering fertilizer can be given in early spring.
