Douglas Spirea

Also known as hardhack or steeplebush, Douglas spirea (Spiraea douglasii) is best known for its large, pink, pointy clusters of small flowers that bloom from May - July.  The flower clusters turn dark in late summer and linger on the plant for months, adding visual interest.

A fast grower that can reach 4-6' feet tall in just a few years, Douglas spirea favors open sunny areas and can tolerate seasonal flooding.  It can spread aggressively in moist environments, but is better behaved in drier areas.

Many butterflies visit this plant for nectar and lay their eggs on it, including pale swallowtail, Lorquin's admiral, spring azure, and mourning cloak.
