This astilbe is hardy from zone 4 thru 8. It grows to a higher height than most, 2~3ft high with a 1~2 ft spread. Per photo, this astilbe grows in clumps and the large, loose, weeping panicles of pink bloom June thru July on arching stems. Stunning!! Like all astilbe this one prefers a part to full shade position in your garden with moist, humusy, organically rich soil. Whatever you do, the astilbe must not be allowed to dry out because the leaves will start to curl and turn brown....that's just uncalled for ugly. You will be able to tell when this astilbe needs to be divided because it will produce fewer flowers and leaves. Normally...most perennials like to be divided every 3~4 years so you should have a gardening bible, of which I call a calendar, to know when anything has been planted.
I do hope you will experiment with this beautiful gem and as alway....Happy Gardening!
