Clump forming and non-invasive. Flowers throughout for a long period, from early spring until late fall.

Type: Hardy perennial

Height: 25 cm

Hardiness zones: 3-9

Location: Sun or part sun

Seeds per pack: 10

Germination: Start these seeds right away to preserve viability, no matter the time of year. Sow the seeds just under the surface of a sterile seed-start mix, and water in. Then cover them with plastic and place in a fridge for 5-6 weeks. Be sure they stay moist. After the cold stratification period they are then brought back to room temperature for them to germinate. Germination is generally within 60 days after the warming period, though they could take a few months. If possible, the best location for sowing in March, April and May, is in cold frame or a cold greenhouse where they will receive the cold period and fluctuating temperatures naturally.
