Curcuma, but I have no idea what species nor what its common name is. If I were to guess, I'd say it's definitely not Curcuma alismatifolia.
This plant arrived in our garden due to another case of mistaken identity. As it's always the case, I'm left with the tedious task of identifying this "alien" plant which Mom brought home.
It happened when I asked Mom to buy some Siam Tulips (Curcuma alismatifolia) for our garden. After an exhaustive search she could not find a single store that sells one, but she was very happy to tell me that she found some growing in my Aunt's garden. I, of course, was glad to know that because of the possibility of getting some starter plants from my Aunt --- at no cost!
And so Mom brought home some offshoots from my Aunt's garden. She took care of them until they flowered and multiplied. Then came the pictures which arrived by e-mail. I was excited (as always) to look at the pictures of our new plant. And there it was, another breed of plant so similar but not quite the plant I was looking for. Still it's beautiful and I'm glad it's growing quite well in our garden. If only I know its name...
I know it's not Siam Tulip because the Siam Tulip has narrower leaves, while this one is broad. I still would like to have the Siam Tulip someday, in addition to its relative that we have now in the garden. But for now, I'm contented with this plant and would love to see it multiply and occupy a bigger space in our garden.
