Gardeners grow them from seed, cuttings from other plants or buy young plants from garden centres or nurseries.

Hi Drdevakiipj and welcome to GoY if you click on the Garden Centre button top right you will be in the selling area of this site. You might find a mail order seed firm who will sell you seeds.

Try this link Drdevakipj http://flowersofindia.net/misc/nurseries.html#Kerala. The nurseries there do some of the plants found in UK. Welcome to GOY. If you have difficulty finding specific plants it may be because the seed is only available from limited sources. Come back on and ask about ones you are having difficulty with as there are members in practically every country in the world although the majority seem to be in UK. As the GOY site is based in England most of the advertising etc is geared towards UK.

I have been to Kerala Drdevakipj - and it is truly beautiful. You will have to water your plants really well there, especially if they are usually grown over here, because I know how hot it is. Good luck and welcome to GOY.
