|I live in Fairbanks, where the winter temps regularly hit 40 below zero and can get to 60 below. Can I grow asters? Are there any specific varieties that would do better than others?
|You can grow asters in your climate, but instead of expecting them to be perennial, count on them to perform as annuals. Your winter weather is too extreme for the roots to survive, even with heavy mulch as protection. Plant your asters each spring and enjoy them through the summer, but don't expect them to reappear the following year.
Some asters which do especially well in Alaska include 'Dwarf Queen', 'Crego', 'Red Mound', 'Dwarf Spider' and 'Pink Lady'.
