Mine grew 6' tall in its second year, and apparently this is common. The foliage is confined to the lower 3', and the huge inflorescence extends 3' above the leaves. It does look a lot like a goatsbeard (Aruncus dioicus).

It blooms here (Boston Z6a) in late June.

Like other astilbes, this species needs consistent moisture and protection from afternoon sun. Hardy to -25F (USDA Z4b).

I wonder if it can be hybridized with Astilbe taquettii...

Be sure to cut back faded flower stalks. Extra water may be needed in dry periods. Divide after 3-4 years in spring or fall. Astilbe requires a lot of nutrients, so give it some fertilizer at least once per growing season.
