Summary
Striking yellow, three-petaled flowers, borne atop mottled grayish-green to blue-green leaves, makes yellow trillium an especially attractive perennial. Yellow trillium is among the easiest of all trilliums to grow and thrives in filtered shade, well-drained, and neutral to alkaline soils. It grows up to 16” tall where adequate moisture and nutrients are present. In addition, yellow trillium has a very pleasant lemony scent unlike its close relative, toad trillium (Trillium cuneatum). Yellow trillium is an excellent companion when naturalized with Phlox divaricata, Uvularia grandiflora, Geum fragarioides, Cypripedium parviflorum var. pubescens, and Adiantum pedatum.
