I have grown Sweet Success for years. My very favorite.
A few times, I have grown other types to compare... and never grew them again.
I had an awful time finding Sweet Success seed this year. A local nursery said that there was a crop failure where ever most of the Sweet Success seed is grown. They had enough seed left from last year to start 3 flats of plants. Thankfully, I was able to buy some of their plants.
Pinetree Garden Seed in Maine is where I normally get my SS seed. They suggested "Diva" as an alternate, so I got one pack of Diva seed. I have not started the seed for those yet... almost ready to pull out the sugar pod peas then I'll start some Diva and see how they measure up.
They would have to be one heck of a cucumber to match Sweet Success!
Sadly I did not plant Sweet Success this year. I was late ordering seed, so I just picked up a couple of things from the local stores. Two years ago I got a sweet success plant that was infected with anthracnose. Last year it looks like even my seeds had the same problem.
I get my SS seeds from Jungs. Good to know there are other alternatives.
My Mom grows Sugar Crunch. It is not seedless, but is a really amazing performer. I pick the fruit young for less seeds and better taste. I planted Sugar Crunch and Burpees Sweet Burpless, hoping it might come close.
