nurseries in san antonio?

We will be heading to san antonio this weekend and would like to visit some good nurseries. Any recommendations?

Thanks, Kim

Rainbow Gardens is nice, two locations, lots of plants and gardens.

Then there is the Antique Rose Emporium on the NE side. If you're really into herbs and don't mind a drive out west of town, there's the Herb Farm.

And BTW, if you'd be in town Saturday morning or early afternoon, there's that plant swap on the NE side!

Shades of Green is a great place to visit!

Thanks for the suggestions everyone! I had already considered Shades of Green, so it's great to hear feedback on it. Unfortunately I don't think we will have time to attend the swap. We will only be there overnight.

Thanks! Kim
