Tim, I'm in a zone 4+, meaning that some years we're very close to being a zone 5 and other years, we're closer to the parameters of a zone 4. Can we all say La Nina?!?
I start a good many of our veggies in the green house each year, usually consisting of things like chard, spinach, lettuce, cabbage, cauliflower, broccoli and beans. Taters are a must have in our garden every year, and every year I plant at least four different varieties.
I've found a blue potato from Irish Eyes that I really like. It keeps exceptionally well and holds its color pretty good through cooking as well. It's lots of fun to use in everything from fried hash browns to putting some great color into potato salad! Hmm...lemme see if I can find you a link...they are really great folks to work with over there at Irish Eyes. Top quality all the way! Oh yes! Here it is! This is the link to their page about the "All Blue" mini tuber. Check it out:

These folks are located about 90 miles due west of me and I have always been thrilled with my order. They fill orders quickly and I don't think I've ever had a single substitution due to an item being out of stock. Then again, I'm always placing my order with them in late January or early February, so that might explain it. I'm sure that if I waited until the end of the pre-spring rush, I probably wouldn't get 2/3rds of my order filled. Yes, they are that popular! Not bad for a small mom & pop outfit!
Anyhow, I've grown at least 12 different varieties of their potatoes in the last three or four years, and every crop has been outstanding. Even those crops where I messed up badly by planting two consecutive years in the same bed.
My bad!
This year we're going to try something new...or at least new to us....and that is growing the spuds in wire cages filled with straw or peat moss or whatever we happen to have handy. The whole idea is to set your seed potato in the ground as you normally would, but then, instead of mounding the dirt through the growing season, one uses a mulch of one sort or another, layered in the cages. As the plant develops, add more straw, hay, whatever to the cages. Just like you would with soil in a conventional row.
The tubers supposedly grow much larger and require less water in doing so. The best part of all comes at harvest. Instead of damaging nice big taters with the spud fork, hunting around for them in the dirt as we usually do, we will simply remove the cages, pull away the straw and voila! Big, fat, CLEAN spuds!!
I'm so excited about the prospects of this method. If this works, I might never have to buy another sack of spuds as long as I live!
Can you tell that taters are my most favorite crop out of the entire garden?
I could make an entire meal just out of a nice big tater with butter and sour cream!
Anyhow, my other source for seeds Tim, is one you might be familiar with and that is Henry Fields.
http://henryfields.com/default.asp?bhcd2=1293560791 If you're not familiar with them I'll tell you of my experiences with them. By and large, good honest folk. However, do NOT order live plant material from them. I guarantee, that with the possible exception of strawberry starts, you'll be disappointed. Especially with any tree purchases. For trees, shrubs or any other landscaping plant material, you're much better off going to Home Depot or Lowe's, or better yet, your local nursery. There you'll be able to see the actual item you're purchasing. They make it look real good on the online catalogue, but once you receive your order, you'll see why I don't buy my actual plants from them! For seeds, they're great. I've enjoyed a near 100% germination on nearly everything I've ever planted from them.
A few recommendations on seeds from HF would be: Corn: Sugar Baby and Kandy Korn. Both yielded a bumper crop for us in 2009. We won't even discuss the 2010 growing season, TYVM! It was a total bust! But not on account of my seed sources. Nope, that was strictly Mother Nature induced. Anyhow, Watermelon: We like one called, again, Sugar Baby. Small, dark green fruit, and each vine usually produces at least 8-10 cannon ball shaped 4-6 pound fruits. Perfect for one person who really loves watermelon, or to share if your appetite isn't quite that big. Oh yeah, and the chickens love it too!!!
If you want a more detailed list than what I've mentioned here Tim, feel free to PM me and I'll give you a complete rundown of everything we plant on an annual basis, along with anything new I'm contemplating for this coming spring. I'm sure I've bored everyone to tears with this list already, short as it is!
