Japanese anemone is most obliging in the garden // Plant may be best perennial for early fall
|
One of the most obliging of all garden plants, and maybe the
best perennial for the early fall garden, is the Japanese anemone.
Once you have it, you have it. There is no question of
replacing it every few years. It spreads moderately but is not
invasive, and so far as I have seen, it is not bothered by mildew,
viruses or bugs.
From a tuft of basal leaves it sends up flower stalks 3 or 4
feet high with many buds that open over a period of several weeks.
The individual flowers are about the size of silver dollars, either
white or rose pink, with conspicuous yellow stamens at the center. ...
