I believe this is from summer breeze and ventricosa. Although neither of theses two are I bloom at the moment. I kept it because I thought the leaves might develope into something but they stayed super suttle. Today I took noticed of the bloom. I hope it comes out a deep purple. This is a sink or swim plant hence the lack of love and damaged leaves. Should try to find it a better spot, but limited space means he stays put for this year at least.
