Yellow Trillium - Trillium Luteum

Yellow Trillium is a showy spring-blooming wildflower with golden, three-petaled flowers and mottled leaves, typically found in woodlands and forests. They are an excellent choice for landscaping due to their numerous positive attributes. These beautiful native North American wildflowers possess unique characteristics that can enhance any garden or outdoor space. From their striking appearance to their role in promoting biodiversity, they offer various benefits for landscape design.

Also known as luteum, it is a member of the lily family. It blooms between April and May and produces a faint scent of lemon. Due to its growing pattern, these gorgeous flowers can be planted next to other perennials that bloom in mid- to late summer.

The Stunning Leaves Of The Yellow Trillium

Each of these plants has three leaves, and they range in appearance from dark green to light green. Additionally, they may have a few hints of silver, which gives them an extra pop of color. Over time, these herbaceous perennials can grow up to 16 inches tall. You'll see yours grow and expand, but you can divide them during the summer.

One trimerous flower sticks up out of the trio of leaves surrounding it. In keeping with the pattern of its leaves, the flower has three petals, three carpels, three stamens, and three sepals. Interestingly, these flowers do not have stalks, but they do have erect petals. Once their flowering season ends, these plants will dormant in the summertime. However, they'll exit dormancy for the late winter season.

One Yellow Trillium Gives You Many Butterflies 

They are self-seeders, so once you've planted the first one, you'll typically see others rise. They rely on ants to help them spread their seeds. Each new flower will grow beautifully from the plant's center and stick straight into the air.

Meanwhile, the leaves grow outward and may slightly swoop toward the ground. The mottled leaves can vary in intensity, with some being primarily green while a light gray shade almost entirely covers others. They provide the perfect backdrop for these stunning light gold flowers.

This Perennial Can Be Planted Anywhere In The Shade

Although Yellow Trillium can be planted anywhere, they have a unique natural habitat. They typically grow around the Great Smoky Mountains, where they help bring light and beauty to the area. What's truly unusual, though, is how many will naturally arise in Gatlinburg, Tennessee. It's unknown why they flock to this specific city, but it certainly provides a bright point of interest for those living there.

Care

Yellow Trillium thrives in well-drained, rich soil. Water regularly to keep the soil moist but not soggy. In early spring, fertilize lightly with a proportional fertilizer. Avoid disturbing the plant's roots and ensure it has adequate growing space.

Plant Reproduction

Yellow Trillium spreads by self-sowing and clumping and also through underground rhizomes.

Planting bare-root perennials is best in any season if they are dormant; we only sell dormant plants. Planting them year-round is also excellent if you can get dormant perennials. When your bare-root perennials arrive, soak the roots in water for a few hours to rehydrate them. Lant by digging a hole wide enough to spread the roots comfortably and deep enough to place the top portion crown (where the roots meet the stem) at or slightly above ground level. Position the plant in the hole, backfill with native soil, and gently firm the soil around the roots—water well after planting to settle the soil around the plant and eliminate air. Apply a 2-3 inch layer of mulch to keep weeds at bay and moisture locked in, keeping the mulch away from the crown. Irrigate plants regularly during the first few weeks of drought; never water in full sun, and water late in the evenings to ensure the roots are established well. Fertilize sparingly in the first year, using a balanced, slow-release fertilizer in subsequent years as needed.
