I bought Calico Jack as a potted single fan in late summer 2014. It has come through three winters just fine, but it is still a single fan. I have noticed that some evergreens take a few years to get going and multiply in my northern garden and I hope this is the case with this one. The fan it has looks great, and it has bloomed both in 2015 and 2016. My camera has trouble capturing yellow, and this is a brighter yellow than is shown here, but this photo was taken late in the day, so the yellow had mellowed and was not as bright as some of the photos here.
