Masses of honey-scented white blooms in summer, over thick rubbery foliage make for a unique and unusual focal point plant in the garden! Spring shoots are unusually purple. Flowers are loved by butterflies and hummingbirds!

Type: Hardy perennial

Hardiness zones: 4-9

Height: 40 cm

Location: Sun

Seeds per pack: 3 Large seeds

Note: These seeds are in very limited supply, and new stock is difficult to obtain.

Germination: As with many perennial seeds, these seeds can benefit from a period of moist cold to help them grow. This is done by giving them a cold 'winter' period (artificial or natural), and then a warming to simulate 'spring', and time to grow! Here's how this can be done:

Obtain a planting container that has holes in the bottom for excess water to drain. Place the seeds just under the surface of your growing medium, and water. Place your container in a cold area (but not freezing, perhaps a refrigerator) for 4-6 weeks. Once the cold period is completed, place the container at room temperature for them to germinate. Be sure to keep the soil moist during this entire germination period. Seedlings will sprout a few weeks, or occasionally several months, after the warming period.

If you are planting your seeds in late winter or spring, these seeds can be planted outdoors while it is still cool out (once the ground is workable and unfrozen), to receive the cold period naturally in the garden. It is best to use this method only if you are able to keep the soil moist for the entire germination period.
