Patrinia Scabiosifolia - Golden Lace
Patrinia is a genus of herbaceous plants in the honeysuckle family. There are about 17 species native to grassy mountain habitats in China, Siberia and Japan. These are unassuming clump-forming perennial plants having thin, erect stems with few leaves and bearing a terminal inflorescence with yellow or white flowers. The use for this plant is to provide a flower through long hot summers.
This is a very beautiful and trouble-free plant for open sunny dry areas. The blooming period starts in July and continues past mid August. It displays a multitude of small golden yellow scented flowers on 3-4' stalks. With some extra water during dry periods, it may grow another foot without it falling over. We never give Patrinia any fertilizer. Many kinds of insects frequent these flowers and I have counted at least 6 different types of bees on a single umbel. A stout plant, Golden valerian holds up against strong winds and the dried flowers are stunning in contrast to snow.
