Grower Information

Heuchera is a relatively fast-growing crop that can be planted from the cool early spring months into summer for spring through fall sales. Provide consistent moisture while plugs are being established, then run them on the drier side. Best coloration is typically achieved in part shade; lighter colored varieties require more shade to prevent burning. H. villosa cultivars are especially well-suited to areas with hot, humid summers.
