Thanks Susan. It's a Japanese. A pleasant surprise since it rained most every day during bloom last year.

Does it need a lot of water? I hear they are heavy feeders, what do you use for fertilizer?

I'm not sure what I do is a good guide as I've only been growing for a few years. Per Polly's recommendation I fertilized in September when they're setting flower buds. I used a balanced time release, heavily. In early spring I pulled mulch back and applied composted cow manure, heavily, then re-covered w/mulch. Balanced fertilizer, per recommendations, early June. Being in New England I have acid soil and our Spring was fairly wet so supplemental watering was minimal, but more than 1" per week.
