Its size and shape is similar to that of a mature, flowering heuchera, and it has spiky balls with each spike a separate seed.
Native perennial, not a shrub.
Thanks!! It is growing in my mother in laws pots, and Ive been collecting seeds. The leaf shapes are lovely!
You may want to rethink the seed collection. Although it is native it is considered a weed in gardens by many people since it self seeds so widely.
