Perennial astilbe are astilbes. When cared for over the winter, they’ll come back in the spring and bloom again. The best blooms should be cut back next year. Plant them in full sun, but don’t let them get too close to the sun.
Too much sun will cause them to over-bloom, which is not a good thing. If you want to grow them indoors, you’ll need to keep them away from direct sunlight for a few weeks. This will help them stay green and healthy.
