How to Grow and Care for Convallaria keiskei
Hardiness: USDA hardiness zone 3a to 7b: from -40°F (-40°C) to 10°F (-12.2°C).
Lily of the Valley is easy to grow despite its temperamental reputation if you buy it ready potted in spring. However, dried crowns take ages to get going, do not always survive, and may also prove difficult to establish if supplied in chunks by friends. In both cases, pot up the crowns separately in loam-based compost, water well, and allow them to establish for a year before planting out. (You can do the same in midwinter, forcing the crowns for an early show indoors.)
At planting time, work in some humus, good garden compost, or, even better, leafmould. Spread out any underground stems and cover with just a couple of inches of the planting mixture. Mulch well with leafmould. If flowering is poor, an occasional dose of high-potash organic liquid feed may help.
