Lovely. A bright bit of sunshine for your apartment. My P. orpenii is also still flowering. Tough little plants. Yes, I think you do have more sun than the average windowsill. Of course it depends on how much sun the European weather provides. Today here in Maryland, no sun, viel Regen, Blitz und Donner. Thanks for sharing your beautiful Prepodesma flower with us.
Prepodesma flowering is rare for me. They haven't flowered since I got them (couple of years) so this is quite exciting. I think the other one will drop the flowers after all though.It's still summerly hot and sunny here :)
