Sasanquas are members of the Camellia family. They are less well known that their larger cousin the Camellia Japonica. Both, though, have dozens of different varieties and a wide range of colors. Here in Georgia, Sasanquas generally bloom in November and December and the Japonicas in January and February so if you have both varieties in your garden, you can see color all winter long.
This Sasanqua is in a spot where it has to be pruned to control its growth. As a result, it usually doesn't have many blooms. I've thought about moving it to a place where it can grow unchecked, but the shrub is well established. Seeing the pretty red blooms has made up my mind about transplanting--I want to see lots of red blooms next Christmas!
