Thought about clovers today. If the native Trifolium wormskioldii (Springbank clover) is so cool, what about the other native clovers around here? I haven't noticed any other native clovers in the area, but according to Jepson there are 30 species native to CA (and several subspecies) and possibly 13 of those species are native locally (and are candidates for introduction to the "coastal prairie"). Unlike T. wormskioldii, most of the clovers are annuals, which makes introduction a bit more challenging.
Here are some potentials:
1. T. fucatum (annual) Bull Clover. This is my top choice for introduction because it's beautiful and distintive (see picture above, from CalPhotos). Also, seeds are available from Larner Seeds. Haven't ordered anything yet.
2. T. macraei (annual) Chilean Clover
3, T. microdon (annual) Thimble Clover
4. T. variegatum (annual) White-tipped clover. This one is unbelievable beautiful, based on photos from Calphotos.
5. T. eriocephalum (Perrenial)
If you would like to spend a good chunk of time perusing CA clover diversity, go to the CalPhotos website and type "trifolium" in the scientific name query box. Coupled with the Jepson Manual, CalPhotos is turning out to be a great tool for identifying natives, or just brainstorming what might be interesting to try in a garden.
