Bougainvillea 'Barbara Karst'
This variety of Bougainvillea is one of the better ones for cultivation in our area. We have had it in a pot for several years now. It usually blooms during the winter and invariably needs to be dug out of a corner when it starts to bloom. I don’t try and use it during the summer anymore since it usually only has a couple of scattered blooms. It is nice to have and I am jealous of the people that can grow it outdoors year round. This specimen is kept in control by occasional shearing because in a container the natural kind of wild growth habit wouldn’t be acceptable. Other than that it takes virtually no maintenance except a handful of granular fertilizer once in a while.
This photo shows the actual white flowers of Bougainvillea. The colorful parts are bracts, which are modified or specialized leaves. It is one of the showiest examples of bracts that I know of. They help in attracting pollinators.
