How to Grow:

Start seeds indoors in a soilless mix in mid-March, keeping them at 18 C. Seeds germinate in 2030 days. Grow under artificial light, harden off, and transplant to a sunny location. Alternatively, sow directly in the garden between mid- and late May. After flowering, trim plants to 5 cm for a tidy appearance. Two grams of seeds cover approximately 4 m.

Snow-in-Summer is perfect for brightening rock gardens, containers, and borders while being deer and rabbit resistant.
