I'm not a tidy gardener -- I like that feeling of autumn abundance with the blousy, ultra-ripe blooms of volunteer plants and super-tough perennials like the lantana. The big tropical hibiscus bushes also like the autumn weather and there are usually quite a few bright red pops of color from those bushes (but not in this photo).
My garden has been ignored and neglected for the past three months. I watered it just enough to keep it alive but it had absolutely no loving care from me this year. I'm happy to have so many happy blossoms even if they are somewhat unkempt.
