'Alert' Aster is a dwarf variety, growing to only 12 inches tall. In late summer its' neat, compact, mounding habit is covered with brilliant purple to crimson flowers with striking yellow centers. One of the best perennials to insure late season blooms. (Symphyotrichum dumosum)
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low
temperatures; the lower the zone number the colder the winter.
If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will
survive the winter temperatures in your area.
If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack
of freezing winter temperatures do not provide a time for winter dormancy (rest).
'Alert' Aster is a member of the famous dwarf aster group. Growing a dwarf aster is one of the very best ways you can assure some fall blooms for your meadow or garden. They are simple to handle and hardy as oaks. 'Alert' Aster stays short, and will fill it's space with a neat, low green tuft that bursts into bloom in late summer with deep purple to crimson, starry flowers. After about two years, you can dig up two or three plants, and divide them into twenty...and then replant yourself a huge patch, or have yards of edging.
The dwarf Aster dumosis (now Symphyotrichum dumosum) hybrids resulted from a cross between wild Aster nova novi-belgii, the much taller New York Aster, with another wild aster from the Pacific northwest.
