Possible sources of info:

Your local agricultural extension office: Select your county here. (You may also want to ask them if they can put you in contact with a specialist that deals in this type of fruit - and, yes, there is one.)

Local growers: Choose your region for a local list. (You may find that expertise varies greatly, but some of these farmers may really know their stuff.)

Websites of other strawberry suppliers: This may be the list you mentioned. (Hartmann's Plant Company, Indiana Berry & Plant Co., Nourse Farms Inc., Sakuma Bros. Farms, and Simmons Plant Farm all have info on the strawberry cultivars they offer. Do keep in mind that they are trying to sell their stuff though.)

GW's Fruit and Orchards Forum: You can also try the search function. (The advise here probably won't be local and may not be professional, but it might be useful.)

Thank you so much for the information, Brandon. The list I referred to was actually one of your posts on this forum!

I've recently moved from MI to TN, and I've grown Earliglow in MI. They were spectacular June bearing plants, and produced the best crop of 7 varieties I've tried, including Mara DeBois. Mara DeBois had nice fragrant flavors, but it was everbearing and didn't produce heavy sweet crops like Earliglow did. I've tasted Jewel from a farmer's market, and it was ok, but it couldn't beat Earliglow especially when they were vine ripened in your own garden.
