Last summer when all my other tomato plants had succumbed to blight, Matt's was still going strong. It's always the last thing standing. Although the seedlings are very slow to get started and even by transplant time look weak and pale, once they get going, watch out. Even here in New Hampshire they grow to enormous size (think 7-foot shrub). And in the fall, only a hard frost will kill it.
The fruits are delicate, degrade quickly and should not be washed until just before they are served or they will swell and split within a half hour. But the flavor is just as delicate.
I have grown Matt's Wild Cherry for many years and I wouldn't consider my garden complete without it.
