Is that the name of a nursery? Or do you mean you can buy one of those trees and want some input? If it's the latter, you've given zero info. on where you live, whether you can (or plan to) grow outdoors or only in (in which case only tropicals are possible, but usually need special lighting, humidity - nonspray kind - and more, and if you've ever done bonsai before, etc.

i have no background of Bonsai before. SO should i stop before i get some good info about it. Is that really so complicated. Should i first read some books before trying them. Can you tell me names of few books. Thanks

Go for a juniper. Junipers are very forgivable trees and do well in almost any climate. You do have to keep them outside though ass they require a dormant period. Do not go with tropical or so called 'indoor' trees unless you live in a (sub)tropical climate. For most people it is impossible to reproduce perfect environmental conditions for these trees to grow well indoors. So it could lead to disappointment ass you work so hard to keep it alive and the tree eventually will give up on you. Even if you are capable of reproducing such conditions, you wouldn't like living in it yourself (high humidity, high temperatures and lots of sunlight).

Indeed you should learn a great deal about bonsai in order to care for it properly. Getting a book may help you with that. "Bonsai - pocket encyclopedia (RD Home Handbooks)" by Harry Tomlinson is a good one. You can also read a lot on the internet nowadays. Good Luck!

It can be complicated - you can't grow bonsai (or trees) like house plants. You need to know about how to mix soil components, whether your climate suits what trees, which season to do what to the trees in (and not) and a whole lot else, not the least of which is how to water properly... no once-a-week juice glass dumped on top!
