I have this in my Courtyard here in Spain. I'm not sure if it is one of the house plants we brought over from the UK or if I bought it here but I have had it for several years and it has only recently been transfered from a pot to a raised flowerbed which has partial shade. This month for the first time it has produced spathes (2)! I searched on the internet to actually see what the plant was & all about this odd pod! On some of the sites it mentioned that the Spathe opens & displays the Spadix for a day before closing & that is exactly what mine has done! Unfortunately I forgot to go outside last night to smell the lovely smell it is suppose to produce at night! Still I am hoping that when the 2nd one opens I will catch it then! The plant has taken on a whole new concept for me!! How often do they actually flower once they start? Is it every year or bi-annual or what?
