I bought a triple fan of Baby Blue Eyes in 2016. It bloomed the first season and I used the pollen successfully for hybridizing that summer. It did not bloom last year, 2017. An overhanging tree branch was shading it more last summer because of an extremely wet season. This spring we pruned the tree back and much more sun is reaching this part of the garden now, so it should bloom better.
I went out and counted fans, and this spring, 2018, it has 13 fans, so it is a vigorous grower. It also came up early and well even with a cold, late spring this year. I hope to see blooms this year.
