A bright green ground-cover topped with cute pink flowers in summer. Once established, these plants will gently self-seeds and spread to form drifts. If they decide to grow somewhere that you don't like, they are very easy to pull up. An ideal ground cover for shade, even tolerant of poor soils under evergreen trees.

Type: Hardy perennial

Height: 10"

Location: Sun or shade

Hardiness zones: 3-9

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 in 14-60 days after the warming period. 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.
