Mr. Mustard SorbariaAlso known by its common name "False Spirea," this cultivar has some of the most interesting foliage we've seen! Colors are all over the spectrum, as tones of yellow, orange, red, pink, and lime green all can be seen as new growth emerges in the spring. Summer brings creamy white flowers, similar to that of the perennial favorite Astilbe, and is fantastic as a butterfly and pollinator attractant.
