I'm a big fan of Lazy SS farm (www.lazyssfarm.com). Their plants are beautiful and healthy, and their shipping method is beyond expectations. Their service is great, too!
I used to order a lot from Bluestone, but their prices have really increased. I used to love purchasing the smaller plants from them just because they were easier to plant in some situations. I"m also not a fan of the coco pots--they just never seem to break down as well as advertised. I'm really disappointed in their decision to change their business in this manner.
