Welcome Susan. The best places to find out if you can buy a particular plant is (1) in the Classified forum, or (2) open up the database listing for the plant you want, then click on the line "X members have this plant" which will bring up a list of folks who own the plant. To the right of each name will be a column letting you know if they are are willing to sell or trade that particular plant. If so, you can send the person a treemail for specifics. Please note, however, that it is impolite to ask someone to buy or trade unless they have indicated their desire to do so. Hope you enjoy this site. Poke around and get to know it.
