Coming to Australia from England, I knew turmeric only in powder form and was really surprised to see the root for sale in local markets (it looks a bit like yellow ginger). About 18 months ago I stuck a piece of it in the ground. It sprouted broad thick leaves and looked fabulous for a while but then just disappeared. I presumed I had killed it but it poked through the soil again in November and flourished in the summer rain during January. A few days ago noticed this fantastic flower.
I'm not very good at learning about all these new plants. I just stick them in the ground and hope for the best. When things thrive and flower, it takes me a bit by surprise!
