Google.com is a good place to start. First hit in Wisconsin is just outside Milwaukee. They may be great or not so much!

Barthel fruit farm

After 178 years in business the farm itself is an old heirloom lol. Good Grief, Charlie Brown, they sell some Native American heirloom [sic] called Cherokee Purple :-)

Cheers

Yes, I've googled. Problem is while a lot of places claim to offer heirlooms, I'm not traveling an hour to find their collection consists of half a dozen Brandywines. Google also doesn't tell me the quality of the plants. Hoping to tap the collective wisdom here for an additional supplier.

Good idea, just don't assume you can't get excellent info on the net which is only a phone call away to verify and it won't take long to see if they are a friendly and honest place. Usually in the first 10 seconds you can figure it out with a phone call.

If you don't like some of the great heirloom tomatoes listed by Barthel
which really looks like a much more fun place to visit, go to Plant Land by Milwaukee airport. Plant Land specializes in heirlooms and has a greenhouse filled with heirlooms, so many, in fact they show them off on their facebook post of last week: Plant Land 1. Plant Land 2. Here is the picture last week for your judgement of quality: Heirloom House: They even have a Pink Heirloom called Sheboygan.

I certainly would try both before they close today. It's transplanting time, isn't it?

My point is not to be critical, but to be real. When people post here they usually do a little bit of footwork which anyone responding really appreciates. You certainly do not have to drive to the Dane Co farmers market with these two, and those were the first two that popped up. If the collective wisdom doesn't have something that suits you more, you now at least have them, their variety lists and pictures of the plants for PL and to be honest they are clearly better than anything in my huge city! Good luck and cheers.

If all else fails many times local nurseries and even small independent growers will grow them for you if you provide the seeds for what you want. But I agree with PC that often a simple phone call will put you in touch with a good local grower. And even if that particular one doesn't grow heirlooms they love to pass on recommendations to others in the area.

And around here even the big box stores have started offering more of the most popular heirloom varieties like Brandywine, Cherokee Purple, Black Krim, etc..

But bottom line - those who prefer to grow heirlooms often find that growing them from seed at home is the best solution. The demand for them simply isn't that great in some parts of the country to justify a big commercial investment in them.

Mileagers in Racine or Sturtevant. I know it's a wee bit further than Milwaukee but they have a lot of heirlooms there.

What about Walmart? There must be one nearby, and I've seen plenty of heirloom tomato plants there. Maybe not the greatest selection, but....
