I planted 12-18 (can't remember - bought in bags at Costco) Astilbes 3 varieties in early April. A couple did not come up, however the rest did and some are already in bloom. I would say they are Very easy to grow- filtered morning and afternoon sun. No special watering needs, but may require some extra watering this summer. Good Luck!
