Yellow Trillium

Yellow Trillium For Sale | Trillium Luteum

The Yellow Trillium is a striking endemic to the southeast of the United States, and is particularly well known in areas around the Great Smokey Mountains of western North Carolina and Eastern Tennessee.b

It is a rhizomatous, herbaceous perennial and produces a whorl of three leaves, called bracts, at the top of its solitary stem. The one three-petaled flower that this unique plant produces is bright yet pale yellow in color and possesses a subtle lemon scent. The flower has no stem and emerges directly from the leaf whorl; flowers that form in this manner are known as sessile flowers.b

How to Grow and Care for Bare Root Perennials, Tubers, and Bulbs

Bare root perennials, tubers, and bulbs are an easy and economical way to jumpstart your garden with lasting beauty. These dormant plants should be planted in early spring or fall while the soil is cool and workable. Before planting, soak bare roots in water for 1–2 hours to rehydrate them. Choose a location based on the plant’s light needs—most flowering types prefer full sun, while others thrive in partial shade.

For bare root perennials, dig a shallow hole and spread the roots out naturally, ensuring the crown is level with the soil surface. For tubers and bulbs, plant with the pointed side facing up at a depth about two to three times their height. Cover with soil, gently press down, and water thoroughly.

Keep soil consistently moist (not soggy) until new growth appears. Add mulch to retain moisture and suppress weeds, but avoid covering the crown or bulb tops. Once established, these plants require little maintenance—just seasonal watering, occasional dividing, and deadheading or pruning as needed. With proper care, they’ll return and thrive year after year.
