This Himalayan Honeysuckle, or leycesteria formosa, is one of my favorite plants here at Zhutopia. It needs very little care, is beautiful and elegant, and bees and hummingbirds find it quite sexy.
It's a nice plant for the Pacific Northwest. It dies back a bit in the winter but looks good for eight or nine months out of the year. It's both cold and drought hardy, and tolerates all kinds of soil conditions. It also reseeds itself, but not to the point, at least in this climate, of being a pest. I like using it in bouquets because the foliage is nearly as pretty as the flowers.
