Sorbaria Sem AGM, 3LEarly shoots of Sorbaria Sem emerge in a delightful pink tinged lime green, which morphs, as the elegant, fern like leaves mature, into a rich green. These leaves create a lovely foil for the wonderfully frothy, Astilbe like white flower heads that follow in summer. The foliage of this chameleon of a perennial then offers a dazzling display of autumnal colour.
