So @minismallholding, i did some digging and it appears you can indeed buy them here in online nurseries, however they are so easy to grow i would only take cuttings i think...

They are so tasty... i'm planning on making my fish curry tomorrow... curry leaves, mustard, chili, tomato, onion and some fish.. yummy although this would be quite nice as vegetarian with just zuchini and eggplant chunks perhaps..
