These are the tuberous anemones
as opposed to the fibrousrooted typessuch as pasqueflower (Anemone pulsatilla).
All are spring flowering. The most familiar kinds are the ones sold by
florists. Which are hybrids of A. coronaria. These have three inch, very
brightly colored flowers I shades of red, pink, purple, blue or white, often
with striking black or yellow centers. They look a bit like small oriental
poppies and grow 12 to 18 inches tall. Popular strains are the single “De-Caen”
hybrids and the semidouble St. Brigid and St. Bavo.
None are reliably hardy as
fulgens is similar in flower and growth, bright red and a little hardier. A.
blanda “Greek anemone” is hardier still, though a bit less showy. Moreover
daisy like flowers on six inch stems in shades of blue, pink, lavender and
white carpet the ground and may survive as far north as Zone 5 with winter
mulch.
Well, if you want to grow
Anemones, then this flowers like full sun but can take part shade, especially
at midday. The soil should be well drained and can be lightened with organic
matter for better growth. Add some lime if the soil is acid or if you have used
an acid material like peat to lighten the soil. Soak the tubers overnight in
water before planting. A. coronaria tubers are planted 8 inches apart, 2 to 3
inches deep those of Greek anemones 4 to 6 inches apart and 2 inches deep. If
you live in the north you need not give up on the tender anemones altogether.
Either grow them indoors or plant them outdoors in early spring, then dig them
in late summer and store them in a cool place in bags of peat.
