3 Photos


Summary

Wedge-petal trillium (Trillium cuneatum) is among the most carefree and easy to grow trilliums for massing in the garden, with its attractive upright flowers in early to mid-spring. The distinctive maroon, occasionally yellowish-green, three-petaled flowers are borne on 1’ tall plants, from late April through May,. and are displayed above mottled green leaves. Wedge-petal trillium performs best in well-drained, alkaline to neutral soils in filtered to partial shade. It combines well with Christmas fern (Polystichum acrostichoides), foamflower (Tiarella cordifolia), pinxterbloom azalea (Rhododendron periclymenoides), drooping leucothoe (Leucothoe fontanesiana), large-flowered bellwort (Uvularia grandiflora), woodland phlox (Phlox divaricata), and many other spring woodland wildflowers. Zones 5-8.
