Astilbes are a lovely shade loving plant that with enough water will provide lacy foliage all summer and put on a colorful show in late June and early July. This year they are especially beautiful because rain has been plentiful.
Astilbes like some light and will not do well in total darkness. They need regular watering. Planting them next to a fountain that you fill regularly is a good way to assure they get the water they need.
