I've been seeing these fruits on my daily walks and never a soul about to ask what they are. They appear to grow in pod-like shapes which then pop open. The leaves are very like lilies, possibly 30-35cms high. I see a few groups of them outside different gardens, so may be escapees.
Anyone following this journal for any length of time will imagine how much 'not knowing' frustrates me - can anyone solve the mystery for me, please?
