Answer: Kaylen is a reasonably recent introduction so your local nursery may be correct about the bloom period; an established plant will bloom earlier in the year than one that's still in the juvenile stage. If your garden warms up early in the spring, I suspect the begonia will bloom earlier for you. Since gardens have their own microclimates, the plant may perform differently for you than for someone else gardening in greater Seattle. If you brush away some of the soil you'll probably see a tuber. If so, you can withhold water to allow the tops to die down, then store the tuber in the garage. If you find no tuber, keep the plant alive by taking it indoors until you can plant it outdoors, or sink the pot into the ground in a protected place and allow it to winter over outdoors.
Kaylen hails from the University of Georgia where it was trialled and presented to Terra Nova by Alan Armitage. In Athens, the plant endured zero degree winters and hot sticky summers.
