Early last year I planted one Clematis alpina "Willy" that I purchases as one of those little 2" pots grown by Clearview and sold at Walmart. I've had great luck with these little starts and my C. alpina "Willy" is no exception. But it has behaved strangly, It bloomed last year, a couple of all white blossoms so I thought it really was not an alpina "Willy" so this year I planted an alpina "Constance" next to it thinking the purply pink blossoms would look nice mixed with the white. Both plants are doing well, the "Willy" really took off this year and is approaching 6' tall. Presently both plants are now blooming and my alpina "Willy" really is what it is supposed to be. Now I'm baffled, does anyone who knows more about clematis than I, know why the same plant bloomed white last year and properly white with pink sepals this year? A second question I have is how and when to transplant alpina clematis? I need to move one so that we can move a fence to build my garden shed. Terry E. WA. zone 4
