Well, some convincing evidence is in. These are Wayahead tomatoes - grown from a sample sent with my Jung seed order. They were planted in the garden in late May, some with the red plastic trays that are supposed to convey some mysterious advantage. The plants growing in the red trays are several inches (perhaps 40%) taller and blooming while the ones without the red trays are - well - shorter and not yet blooming.
Here's another variety, Cherokee Red. Am I nuts or does that look like a double flower? All the flowers on the two Cherokee Red plants look like this. Doesn't seem like a great thing for a plant grown for its fruit.
Here's Murphy the Magnificent posing as a garden ornament. I think he looks great there.
