I really, really, really like
Burpee !
The catalogs are gorgeous, in fact 2012 is supposed to be sent out sometime soon here in December.
This year the front page is all about the "Boost veggies"... like tomatoes that have been found to have more lycopene, ect ect with other veggies.
I really love the variety of Burpee. They have Hybrids, they also have MANY Heirlooms of just about everything. It's easy on the site to navigate to just one or the other or both.
This year they have finally added trees... Apples, Peaches, ect ect. Then they always have a great many nice ornamentals, flowers, grasses, ect ect. Really a huge selection of everything. I think theres like 200 kinds of tomatoes on the site?
Plus the funny colored things... like purple tomatoes, blue potatoes, red carrots, ect ect.
They ship started plants to your door in spring/right time for planting... I know I'm planning on that this time.. love sprouting seeds but this will be more dependable for the tomatoes and veggies
And, if you don't like something within a year of purchase, they will refund it
I had a couple seed packets I had to get a refund on, think they had gotten damp, and they were quick and easy about it.
