Hibiscus-like, but we don't have any hibiscus in the garden. I thought it must be an abutilon, as we have several of those, but that was wrong. It isn't from the flower garden at all, it's from the vegetable patch. It is an okra flower!
And the last of the TreeProject species has started germinating:
Desert hakea, Hakea mitchelli. It is nearly three months since the seeds were sown, so we had just about given up on seeing any hakeas. But I guess it makes sense for a desert plant not to germinate until autumn.
