Isotoma

I don't think I've photographed this flower before, with its lovely five-fold symmetry. Or maybe I've just not been paying attention.

We weren't even go anywhere recognisably horticultural today, and this flower was sold at a shop that we were visiting for its range of bathroom tiles. So when I took this shot, I inevitably got a few strange looks from the shop's equally non-horticulturally minded clientele.
