The tops of the stem branches are occupied by plentiful spike inflorescences from March to June.[3] The shrub is generally monoecious, with each upright inflorescence holding mostly staminate flowers with a few pistillate flowers clustered near the bottom. The staminate flowers have large, woolly leaflike bracts.The pistillate flowers have smaller bracts and develop tiny white fruits. The silky hairs on the fruits allow for wind dispersal.
