So I keep a N. ventricosa at my brother's house temporarily while my house gets finished. I likes it there, where it lives in the same pot as a huge N. hirsuta x veitchii. I went to water it today (after forgetting for a week), and found it in flower! Here are two pics, I assume this is a male? I don't have much experience with them flowering, so could anyone confirm this?
Also, if it's a pollen producer, is there a want out there for red N. ventricosa pollen? Ventricosa makes good hybrids! This one grew like crazy right from its humble beginnings in an OSH hardware store.
