A delicate woodland groundcover with pairs of broad leaves and tiny white star-shaped flowers followed by red berries that turn dark blue-black. It spreads slowly via rhizomes and is ideal for shaded forest gardens.

Why grow it

May lily offers finer-textured foliage than many competing woodland groundcovers, with a more delicate appearance than native alternatives like false Solomon's seal. Its slow, steady spread via rhizomes makes it suitable for gardeners seeking gradual colonization rather than aggressive coverage. The ornamental progression from white flowers to colorful berries provides extended seasonal interest in shaded sites where many groundcover options offer limited visual appeal.

Watch out for

Establishment can be slow in the first year or two, so patience is needed before substantial coverage develops. Plants may decline or stagnate in poorly draining soils, particularly in heavy clay. Performance varies considerably depending on local climate and woodland conditions, so success is not guaranteed in all temperate regions.
