Vital statistics: There are about 15 species of hellebore, and hundreds of varieties. Lenten rose, Christmas rose (H. niger), and bearsfoot hellebore (H. foetidus) are three you're likely to find at garden centers and in catalogs. Lenten rose can be grown in USDA Plant Hardiness Zones 4 to 9.
What it needs: One of the easiest hellebores to grow, Lenten rose requires only a shady site, well-drained soil, and an occasional watering in dry times. It blooms best in fertile soil; topdress with compost or, when you see new growth in late winter, apply an organic fertilizer. The compounds that make hellebores unpalatable to deer can also cause mild skin irritation, so wear gloves when handling.
