My wife, who usually doesn't take much interest in these things, picked this out when we were at a farmer's market several years ago. The seller called it a sun hydrangea and claimed it would take full sun. I was skeptical since I've seen many "full sun" plants burn miserably in our hot, intense summers. He didn't have the name on him, but said it was from Japan. I've wondered what variety it was ever since.
It survived the neglect of the overworked that year, living in its pot with little water and a half day of full sun, and doing quite well despite all that. So I put it in the ground, in the very front of the yard where it is fully exposed to the elements and gets full sun all day. It blooms beautifully, like hundreds of brilliant white butterflies, from July to October every year. I would recommend it heartily, if I knew what it was.
