I am looking at Territorial Seed and see that Oregon Spring is a determinate Parthenocarpic tomato. I didn't even know there was such a thing as a Parthenocarpic tomato.
And they also have two other ultra early tomatoes from the Beverlodge series. I have a whole bunch of tomato plants there at Territorial in my shopping cart and am just trying to make up my mind on my finial choices.
