Cistus 'Blanche'....
I had a cistus 'Frank Birch planted in Fallbrook, about 4-5' tall when we left, supposedly will reach 8'...and I loved it. When we got up here, I saw, in Brookings, what I thought must be 'Frank', but learned that it is Cistus 'Blanche'. I did finally get a cutting from bex's friends' motel in Gold Beach and it's doing well now.
This is Cistus 'Blanche' in Brookings, Jer standing next to it for scale...
