Wow. Thanks for the heads up on a few of these. Never thought to try them honestly. For my list:
Swallowtail - Absolutely great selection and they will make it right if things go wrong.
Bluestone - Most times things go wrong, but they do make it right as well. Nice selection of plants/bulbs.
American Meadows - Don't think highly of their plants, but there are times they are the only one to carry something. I do trust to receive plants in good order though.
Easy to Grow bulbs - Nice Selection.
Sunshine Flower Seed - Nice selection. Not every day items.
Outside Pride - I like the amount I get for what I pay. Nice selection.
Eden Brothers - I've bought a couple of things. Mostly not my thing though.
Chiltern Seeds - They are from england. Great selection and prices. They also ship to the US.
Stokes Seed - Not a huge selection but I can find things there I can't in other places or a greater amount in seed is offered than somewhere else.
Rosy Dawn Gardens - Coleus. Only coleus. I do intend to purchase 3 plants from them this december. Kind of pricey but I can't find the seeds for the coleus I want anywhere so may as well buy the plants.
Longfield Gardens - I have not ordered from them but they have an astounding selection. So much so that they are pretty much sold out of the bulk of their things. I keep a close eye on them as I would like several things from them this year.
These are the places I'm most apt to buy from. I like what they offer, if I have any problems with the plants/seeds, all of them are willing to help and do what you would like done.
