I have the seed (Hawaiian Sweet Red Current) sometimes called Sweet Pea Currant also, that you're interested in.
The plant of which I've grown now for a dozen years or so, just keeps putting more and more on as long as you keep picking em. Maybe 200+ on a single plant. (No I'm not kidding). I'd be glad to send you 30+ seeds, all harvested this past November here in Northern VA. If you'd like any other tomato seed(s) I have about 15 other varieties, Ponderosa Pink, Marglobe, Hometead, Roma, Rutgers, Jubilee Golden...etc, Most are Heirloom. and fresh seed, which I could forward. I'm looking for some hot peppers if you have any. Kris

We have been growing Matt's Wild Cherry tomatoes for a few yrs now. They sound like what your describing. They are very sweet, small. prolific, reseed, disease resistant. They are available from Southern Exposure Seed exchange.
