Helleborus niger
WHITE CHRISTMAS ROSE
- Unit price
- / per
Helleborus are absolutely stunning perennial flowers that are widely admired! Foliage is dark green, shiny, and evergreen even in the coldest climates. White flowers begin to bloom as the snow is receding, and continue through spring creating a magnificent display. Flower last for many weeks, and as they fade they turn a jade green color (as shown in images), and remain into summer that way. Helleborus can be best appreciated when planted near the front of the perennial border. We have been growing these plants for a number of years in our zone 4 gardens, and they are always a welcomed sight of elegant color! Of all of the Helleborus seeds that we sell, this one is the quickest to germinate!
Available for a limited time.
Type: Perennial, evergreen foliage
Height: 18"
Location: Part shade or full shade
Hardiness zones: 4-9
Seeds per packet: 5
Sow just under the surface of the soil and water in. First keep them at room temperature for 6 weeks. This helps break the phytohormones which inhibit germination. Then cover them with plastic to retain moisture, and then place in a fridge for 8 weeks. Then bring them to a cool room (approximately 12C, 54F) for 8 weeks for germination. They may be growing at this point, though often they need a second cold period. If they are not growing cover them with plastic and place in a fridge for another 6-8 weeks. Be sure they stay moist. After the second cold stratification period they are then brought back to a cool (12-15C, 54-59F) room for them to germinate. This double cold period is not always needed, but sometimes necessary, and is very normal for these seeds. Germination is in 30-90 days after the second warming period.
Ornamental use only. These seeds and/or plants are poisonous.
