Jade Star - SinglePart of the Winter Jewels TM series, Jade Star is a combination of jade green and plum that make this a unique addition to any garden or bouquet. We like this one so much that we used it as our logo flower. The flowers appear above the foliage winter through May. Like all Hellebores, they are prized for their shade tolerance and deer resistance (all parts are toxic of eaten). They grow best in US Zones 5-8, but will grow in Zone 9 if amended properly.
