This is one of my favorite shrubs. I received it from Ralston Arboretum. I grew it in partial shade in clay based soil with a high ph in Lake County, Illinois and it thrived. I dug it up and took it with me to more neutral soil in full sun in Kane County, under a PJM rhododendron and it was even better. I just got a garden client to buy three directly from Proven Winners. An exceptional shrub, requiring little or no maintenance (compost in the spring and occasional watering).
