I've been receiving a lot of plant catalogs and yes, the pictures are all so beautiful and there are many plants listed that are just different from any other plants I've seen in my neighborhood (making them more desireable). Do you have any success stories with any particular catalogs?
I'd suggest checking out the companies whose catalogs interest you in DG's Garden Watchdog. Reputations can change over time if companies are bought or sold or just encounter problems, so I check there even if I've ordered from them before. The fact that comments are posted along with ratings will give you a good idea of which companies are the better ones... and there's a "top 30" list, too!
