You have to be a little careful; zone 4 in the high country of Colorado is a LOT different than zone 4 in Iowa... they have cold, dry winters and cool, rather dry summers. A lot of high country zone 4 plants turn to a pile of mush in our climate.

Bluestone Perennials is my favorite. I got my "wish book" in the mail yesterday. Everything I've ordered has been in very good condition when it arrives. The only plant I've lost so far is a beautyberry that DH decapitated with the weed-wacker. They have a lot of zone 3, 4 and 5 plants. I'm in zone 5 but I try to plant a lot of 3's and 4's just in case we have an awful winter.

I originally ordered from them because they carry a particular groundcover that I haven't been able to find anywhere else. They have a special offer on most groundcoveres which makes it easier to buy in bulk.
They have a website that's fun to browse.

No better way to spend a Sunday afternoon in January than with my garden catalogs, cup of coffee, blanket and a cat on my lap.

My favorites are Park's and Wayside Gardens (both the same company I believe). Their stock is always reliable, and they offer the newest that comes on the market, especially Wayside Gardens. Wayside offers more unusual stock too.

Never have purchased from Bluestone. but I hear even though their plants are small, have great roots and take right off. I'm not going to order much this year. Plan on dividing and giving many away. That how I got many of mine.

I check out the Garden watchdog before I order. It helps to see what others think. http://davesgarden.com/gwd/

I like Bluestone also but for seeds I like Stokes.
