California Buckeye is in business on Windy Hill * serving up fragrant blooms to hikers, native bees and butterflies, like the Pale Swallowtail butterfly. This shrubby tree, found over much of the Western United States, is a great wilderness plant counted on by many natives. Before European contact, it was also a food source for native peoples, following an extensive toxic leaching process.
It's not a good neighbor in the suburbs, however, since there it may come into contact with non-native bees. That's because it's pollen, though extremely appealing to the European immigrant bees, is toxic to them.
So . . . we love it, but we don't plant it.
