Are you looking for something specific?

No, this lady had everything. A lot of it was lacy looking like cassia are something along those lines. Also, she had a lemon leaf. There were lots of beautiful foliage plants so I'd be happy with anything from that area of the world, it was so pretty!

Here`s a nursery in Thailand. I`ve ordered many plants from them and have always been satified.

I go the swap meet and buy from the Thai plant seller.

I know that may sound silly, but if you are in a diverse community, you might consider going to the swap meets and seeing what Asian sellers have for sale. Sometimes Asian markets will also have exotic plants for sale. You may have to deal with a language barrier, but it is a way to get plants not easily found otherwise.

Where are those swap meets in San Diego? and the asian markets?

The "lemon Leaf" that you saw might have been a Kaffir Lime, aka Thai Lime. It's grown and used for the flavor/aroma of the leaves, and is widely used in Southeast Asian cooking. Not too hard to find here in the U.S.

I have a kaffir lime tree that is bearing fruits right now and I have lots of seeds to sell if anybody interested, let me know. I am located in Houston, TX. I am selling 12 seeds for $5.00 and I pay for first class postage. http://houston.craigslist.org/grd/885158583.html
