This gorgeous shrub loves growing in the summer shade of a Pinyon Pine. This bold winter evergreen delights with dramatic firey growth in spring, producing clusters of fragrant flowers. Exquisite wedding cake layers of white flowers hover on graceful, arching stems most of winter and spring.

Lily of the Valley Care

Lily of the valley grows vigorously in almost any spot with shade. Gardeners plant it under trees where many other plants won’t grow due to shade. A long-lived plant that doesn’t have any serious issues with pests or diseases. It’s helpful to grow it in containers or a raised garden bed to avoid unwanted spread.

This plant needs little attention to thrive once established. Plan to water during dry spells. If bloom time decreases on older plants, it benefits from digging them up in winter and divide the roots to refresh their growth. Replant them where they have more space.
