That was a really good deal .Those are pretty.

Do you mean a P. murucuja? I've never heard of a mujucuna. If it is a murucuja it's a very easy plant to grow. Average water, full sun. It has very thin stems and small leaves but produces a huge number of flowers. The tiny stems don't look like they should be able to support the blooms but they can. It's also very easy to propagate by from cuttings. This is a pic of one of the blooms over the winter. I'm pretty sure they produce fruit but mine have always dropped when they were the size of a tic tac.
