While Black
Pearls produces the darkest
foliage of any astilbe, its vibrant,
long-lasting flower plumes are
what truly set it apart. Each
attention-getting plume consists
of hundreds of tiny, deep purple
florets with hints of blue. They
truly stand out against the plant’s
divided, fernlike, extremely dark
green leaves. Grows easily in
regular to moist soil when the
earth is not allowed to dry out.
