It's seed catalog season, so I thought I'd let you know about some of my favorite companies to get seeds and why. Where you get your seeds from does matter. You want to get varieties that are well adapted to your climate, and a seed catalog that's based in a climate similar to yours will have more of those varieties.
When I first started gardening, I was surprised about how many seed companies are in New England or the Pacific Northwest. They advertised varieties that were quick maturing for short growing seasons, tolerant of cold, etc. Not very helpful for me here in Texas. What I need is heat tolerance and drought tolerance. After a while I finally found some catalogs based in the South that had more of what I was looking for.
Here are my favorites:
Southern Exposure Seed Exchange
More of my seeds come from here than any other company. They are based in Virginia, so most of their varieties are adapted to the Southeast. That's a little bit wetter than my climate, but many of them still do well, and I hedge my bets by also getting seeds from the next company on my list. Their website also has lots of useful information on it, and I like the cute gnome pictures on the front of their printed catalog.
Besides the usual things like squash, beans, and tomatoes, they have a great selection of heirloom collard varieties, many of which I haven't seen anywhere else. Their potato varieties have also been serving me very well, especially since potatoes are considered to be difficult to grow in Texas.
Overall, this is my go-to seed catalog that I check first if I feel like trying a new variety.
Native Seeds/SEARCH
This my second-biggest source of seeds. They are based in Arizona, which is a drier climate than mine, so combining their varieties with Southern Exposure's varieties works out great. This is actually a nonprofit organization whose main mission is to preserve crop varieties that have been grown by Native Americans in the Southwest, so I'm happy to fork over money to them to help support their mission. You can get varieties here you can't find anywhere else, plus some more common varieties that do well in hot, dry conditions.
This is where I bought 10 bulbs of I'itois onions that have continued to thrive and multiply in my garden ever since. My favorite okra, Beck's Gardenville, also came from here (and it's a local San Antonio variety). They also have a good variety of melons, but of course their biggest selection is of the three sisters: beans, corn, and squash.
There's also this really neat ADAPTS tool on their website where you can type in your address, and it will find varieties of plants that came from climates similar to yours. I've used this to help me decide which varieties to try next.
Those two seed catalogs above are where I get the vast majority of my seeds from, but here are some honorable mentions that I shop at occasionally, or get some specialty things from.
Baker Creek Heirloom Seeds
This company is famous for their "vegetable porn" catalog and huge selection. Yet I've found that over the years I get fewer and fewer seeds from them. Most of the varieties I did get from Baker Creek that did well for me are also carried by Southern Exposure. I've also gotten a lot of varieties from Baker Creek that did not do well. I think it's because they don't concentrate on one specific region, so I got sucked in by the beautiful pictures and bought varieties that were not adapted to my climate.
Baker Creek's strategy seems to be to try to accumulate as many varieties as possible from all over the world. That means you can get some really interesting stuff that's not found anywhere else, but you also have to be careful to pay attention to where the variety is from. Here in Texas, varieties from the Mediterranean, or the Middle East, or India will probably be OK. But not things from Northern Europe or Japan, no matter how pretty they look.
So basically, I don't actually buy a lot of things from Baker Creek, but it's still fun to browse their catalog and order a thing or two just to experiment with something unusual. They also have huge seed packets with generous amounts of seeds in them, which may be advantageous with certain crops.
Filaree Garlic Farm
This is where I go for garlic. They have the best selection I've found, including the very hard to find Creole varieties. The bulbs they send are always in very good shape, and their website has tons of information about growing garlic. They specify which of their varieties do well in warm climates, and which need cold climates, and also which ones harvest earlier or later, and which ones keep longer.
Sand Hill Preservation Center
This is where to go for sweet potatoes, though Duck Creek Farms is also good. Sand Hill has the largest variety of sweet potatoes anywhere, many varieties you can't find anywhere else. My only problem with them is sometimes they arrive a little late since they are in Iowa, and I am in Texas, so I can plant much earlier here. If you are in a hurry, try Duck Creek Farms instead, since they are in Oklahoma and ship earlier in the year.
I've never ordered any seeds from Sand Hill yet, but they do have some interesting things listed that I might like to try some day. They do have the problem of being based in Iowa, so I'd have to be careful not to order something that's not suitable for my climate.
Seed Savers Exchange
Another one in Iowa, but this gets an honorable mention because it's such an important organization. This is where the whole "heirloom vegetable" trend probably got started, and they also got me into heirloom vegetables. I used to order more stuff from them before I discovered my two favorites listed there at the top. Their retail catalog is OK. It has a lot of the more famous heirlooms, but many that either are also found in lots of other catalogs (like Southern Exposure), or wouldn't do well in my climate anyway (sorry Pink Brandywine tomato).
If you are into seed saving though, you need to get on the Exchange. I started listing some of my seeds last year. It took a while for them to finally get into the 21st century and make an online Exchange (before that it was just in print), but now that they do have it up and running, it is very easy to list your seeds. Online seed swapping is lots of fun, you get to share the excess seeds that you have saved, and you might find something really interesting listed by another member. Seed catalogs are great, but you never know when they are going to run out of or discontinue a favorite variety, so it's always good to have a network of home seed savers as a backup.
So there are my favorite places to get seeds (and other planting materials) for my garden. If you also live in the South, consider giving them a try if you haven't already. Even if you don't live in the South, maybe I've given you some ideas on what to look for when searching for your own favorite seed company.
Happy seed ordering!
