Vancouvera hexandra, another close ‘cousin’, like our Achlys triphylla, or Vanilla Leaf, all emerge every spring from their hidden running rhizomes, all with distinctive and attractive foliage. Epimedium spp share the same growth habit. All of them do well in similar moist, well drained shady conditions. The Himalayan and Chinese species will require more moisture than our summer dry NW species. This particular planting is in one of the beds at Portland’s City Hall.
