Gardeners' Notes:

I am in southern Riverside County in California, and last year two of these came up just outside our fence, in heavy clay soil. They never got very big, but I was shown some larger specimens just up the road. This year I notice three of them coming up outside our fence, and maybe five that are growing just up the road.

I watered the ones we had last year, & wonder if I should do the same this year.

(The ones up the road always seem to be larger than those outside our fence. But they all look --and smell-- alike . . . like turpentine. It reminds me of when my dad used to paint something!)

I enjoy the small pretty blue flowers on this plant, and hope that it continues to come up next to or in our yard! (:

I also enjoy the smell of the leaves on my fingers, after having rubbed them! (:

Its main drawback would be that it is not fire resistant, perhaps its oils are even easy to ignite. ):

One of the few plants to bloom here in the wild in the summer. The odor of the foliage seems to be an acquired taste. I used to think it was awful. Now I think it is interesting. It does have a vinegar smell, but it is more complex than that.
