Arrowhead vine (Syngonium podophyllum) sold as a houseplant, invasive weed where evergreen, but has been a very satisfying herbaceous perennial. Found growing @ my previous house in 2008, planted by some unknown previous resident. Where I am now, I've propagated several and love these little poofs of fresh new white and pink leaves. This has been much more worthy of my effort than Caladium - which I end up wasting $ on almost every year.
