Fremontodendron californicum, or California Flannelbush, or Fremontia, is a tall evergreen shrub with many smaller varietals, but the californicum variety grows to be 13-20' tall by 15' wide. There are smaller varietals, getting to be 4-5' tall by 8' wide. This shrub hates summer water, and should be planted in well-draining soil or just sand or DG. The plant usually dies because of too much water. An amazing native, seeing this shrub or tree in full bloom can stop the heart. What a gift our state gave us.
