Here’s a plant whose flowers can be white, cream, yellow, pink, rose, or red!! Our plant was grown from seed collected in the wild while Bob was on the road into the Dulong area of Yunnan. Most of those plants were in yellow bloom and the seedlings have all bloomed yellow.
The rounded leaves are unusual and the plant will develop some peeling fawn-colored bark that adds interest. The emerging leaf has a bluish cast.
Found in bamboo thickets in Yunnan, Upper Myanmar (Burma), and SE Tibet, this plant is not often seen in western gardens. One of ours has grown to six feet in twenty years and happens to bloom pink.
R. stewartianum will like: Small amounts of fertilizer on Valentine’s Day & Mother’s Day, gentle watering that keeps it moist, and good drainage with well-aerated soil.
