Early in the season, beautiful daisies in shades of pink, lavender, white and violet cover the alpine asters in this mix. The mounded, low-growing plants are ideal for container culture and rock gardens. The plants are easy to grow but tend to be short-lived.
Unlike many aster species, the delicate, pastel daisies of alpine aster bloom in late spring and summer. This unusually cold tolerant perennial is native across the far reaches of Canada, Alaska and Eurasia. Wild populations grow along montane river valleys, mountain slopes, tundra and rocky coasts. Some garden-worthy cultivated varieties have been bred, which are all considerably tough and well-adapted to cold climates and rocky terrain. Habit varies, some are prostrate and others bushy and mounded.
Full to partial sun and sharply drained soil are essential for this carefree alpine. It will not tolerate hot or humid temperatures, so it's best reserved for northern gardens.
Place this early season beauty in rock, trough or alpine gardens.

2. Place the pot or seed tray in the refrigerator or outdoors in temperatures of around 0-+4C for two to three weeks (recommended).
3. Remove the aster seeds from the refrigerator or their current outdoor location and place them in a climate with an air temperature of at least +18+20C. Leave the asters there for two to three weeks and they should sprout.
