Numerous species and many hybrids comprise the
perennial asters. The most familiar are known as Michaelmas
daisies. Mostly sold are hybrids ranging in height from about 12
inches to over 4 feet. Plants form clumps of narrow leaves and
send up branching spikes of typical daisy flowers, single to nearly
double and generally 1-2" across. Shorter hybrids form almost
solid mounds of color; tall ones are more open and graceful but often
need staking. Colors include shades of lavender and pink - light
to dark - plus white and red purples. Typical bloom season is
midsummer into autumn.
Perennial
asters are not fussy about soil, but they need full sun and regular watering.
Mildew is one problem they develop. They perform best with frequent
dividing, so dig clumps about every other year. Do this in early spring
where winter are cold, in autumn or spring in milder regions.
