Hi Jim, There are Bulbine species from tropical and southern Africa and species in Australia too. Although there are some that qualify as "bulbs", many are perennials. It looks like the ones you saw are a form of Bulbine frutescens which is a perennial. I have a couple of these smaller orange ones in my garden in bloom at the moment. I don't really notice them until they bloom and they haven't spread at all. And in my garden they are not in bloom a very long time in spite of the claims for being long blooming. I also have some of the species in my garden. It has yellow flowers and is a very robust plant someone gave me a piece of when I admired it. She just ripped out a hunk. It is tough, long blooming and expands. Every now and then I'll reduce the area where it grows. When Cameron McMaster visited, he remarked on the medicinal qualities of this plant. Here's an interesting link from SANBI about the species that includes how it can be used: http://plantzafrica.com/plantab/bulbinefrut.htm/ Mary Sue
