Spiraea douglasii aka Rose Spirea
Taxonomy ID: 4661
Spiraea douglasii, also known as hardhack, hardhack steeplebush, Douglas' spirea, douglasspirea, steeplebush, and rose spirea, is a species of flowering plant in the rose family that is native to western North America. This vigorous, clump-forming, suckering shrub has narrowly oblong leaves that are dark green above and velvety white underneath, turning yellow in the fall. In early summer, long plumes of fragrant, rose-pink flowers up to 8 inches (20 cm) long are on display at the tips of the branches. Rose Spirea, a super rare houseplant that belongs to the Spiraea genus and is native to Western North America, is easy to grow and needs regular watering to thrive. It prefers long-lasting, direct light and soil that is good at retaining moisture. Repotting each time it doubles in size should provide enough nutrients, so no added fertilizers are necessary.

The Rose Spirea should be repotted when it has doubled in size or annually, whichever comes first.
