Epiphyllum Nora Cantafio at Wave Hill
Okay, so it is not a bouquet, but this Epiphyllum blossom is impacting. For all the talk about wanting flowers to last and last, I find it interesting that the most popular species of Epiphyllum is Epiphyllum oxypetalum, which blossoms and dies within a night. But what these plants may lack in longevity they make up for in drama.
These plants are very easy to grow from leaf clippings, and make very good houseplants for those that have good sun.
Epiforums is a good place to begin learning and talking with people who have Epiphyllums.
GardenWeb's cacti and succulents forum also has a number of posts for Epiphyllum.
