Yellow Trillium (Trillium luteum)

Yellow Trillium (Trillium luteum)

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.

Growing Tips

  • Planting Instructions:

    Best grown in a moist shady woodland garden setting. Plant so that the top of the root (sprout) is 1" below the soil line. Firm soil and water well.

  • Soil Moisture:

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

  • Will Tolerate:

    Acidic Soil, Clay Soil, Loamy Soil, Sandy Soil

  • Pruning Instructions:

    None. Picking a trillium flower does not kill the plant but damage will result if the green leaves are taken as well. The leaves are needed to provide nutrients for the plants to survive.

  • Winter Care:

    Mulch in late fall for added winter protection.

  • Planting Depth:

    Plant so that the top of the root (sprout) is 1" below the soil line.

  • 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.

  • Fertilization Requirements:

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