Think of the Garden Watchdog as a specialized Better Business Bureau for plant buyers. The database rates -- with customer reviews -- more than 4,700 online merchants who sell gardening products. Among the top 30 most highly rated companies are Just Joey's Roses ("Very impressed with the quality of the yellow rose plant I received in the mail"), Oakes Daylilies ("Love them! Love them! Love them!") and Classy Groundcovers ("Received bare root liriope today in excellent condition").
Thanks, Bob, for suggesting the site.
