Aside from S. purpurea venosa 'Brunswick Red', This is my favorite clone in the collection from Brunswick Co, NC. It has this extremely bulbous feature to it, and the colors are also really nice. Perhaps bulbous clones like this one once gave botanists the impression that S. rosea was the same subspecies.
Nice thing about purps. is the pitchers last throughout the winter, and are usually in perfect condition until about March, when the new pitchers start to emerge. They can also accumulate more anthocyanins and become more colorful, even during dormancy.
