Introduce yourself to your first hellebore, and you're sure to want more. It's just hard for anything to rival that. It's a really durable plant that tolerates a very wide range of environmental conditions. Some hellebores are hardy to Zone 3. Depending on the species and cultivar, you can have blooms all winter long.
Every hybrid is different.
No two hellebores are the same. That's the beauty of them. Hellebores have various preferences for soil and site. Before you take a hellebore home, research the species' requirements and give it the conditions it wants. You'll be richly rewarded.
