These are late summer/fall blooming native wildflowers that are easy-to-grow and provide an ample late season nectar supply for butterflies and bees. As such, they are an indispensible perennial for late season color and for feeding migrating Monarchs. Asters are resistant to browsing rabbits.
Preferred growing conditions:
- They grow well in most any type of soil including clay.
- Mulch with common mulching materials as well as gravel when planted in a xeriscape.
- Most do well with regular irrigation to keep the soil moderately moist. Some species are more xeric.
- Plant in full sun or part sun. Some varieties will stretch in too much shade
- Just a few handfuls of compost and Yum Yum Mix in the planting hole is enough. Don't plant into a rich, highly amended soil. Special comments:
- Species that spread to form wide growing clumps can be divided in mid-spring. Garden Care:
- Fertilize in the fall with Yum Yum Mix and good quality compost.
- Deadheading is not necessary, but will reduce re-seeding of seed-grown varieties.
- Leave standing over the winter months and cut back hard to 1 to 2" above the ground.
- If foliage becomes affected with mildew at the end of the growing season, cut back to the ground and remove the leaves/stems to the compost pile or trash.

USDA Hardiness Planting Zones
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).
