I'm constantly amazed by the different characteristics of tomato plants.
The trusses on my Glacier plants are so close that the tomatoes over-lap each other, that is, the truss above partly hangs over the truss below.
However, the Black Cherry plants have trusses that are such a distance between them that I thought at one point I was only going to get one truss!
Shirley also has a short distance between trusses which is helpful when height is an issue.
In the picture is Sungold ... lovely trusses of very sweet fruit. This year I'm trying Sun Cherry Premium which is supposed to be even better ... we'll wait and see!
