Dear Jane, My husband renamed Allium triquetrum, Allium pestum. It is weedy in Australia and New Zealand and Northern California. There is a state beach where we hike each spring where there is an abandoned house that has slowly deteriorated and is now unsafe. It is interesting to see what is left of what must have once been planted there. It is there along with Zantedeschia aethiopica. On this same beach there is also Oxalis pes-caprae. The form of Watsonia meriana that produces corms in the leaf axils is the other one that has escaped into the native vegetation. Mary Sue
