The Voodoo Lily is one of the strangest plants we have in the greenhouses. The pot appeared empty for months and then something began to sprout. I assumed it was growing leaves but instead it produced this large flower. They're suppose to smell really awful but I guess the scent isn't strong enough yet to be apparent. After the flower dies a single, round segmented leaf will be produced.
The Voodoo Lily is a perennial and enjoys both heat and humidity. It's recommended for zones 10-11. The soil may be sandy/clayey loam and being slightly acidic is often helpful. This is definitely a plant for people interested in oddities! I've also added a picture of a Euphorbia that has produced some tiny 'leaves' on the growing tip.
