There are careless people in all fields.
A major seed company used to sell both Sugar Lump and Gardener's Delight. I've noticed that they recently stopped doing that. The "word on the street" for ages was that they were the same cherry tomato.
With hybrids, some of you may remember how tickled I was to find a couple of potato-leaf plants amongst the Early Girls a couple of years ago. Just a parent ... and not an especially healthy one, at that. Someone wasn't careful about leaving fruit on the plants.
This happened again this year. I've got several plants that were labeled Sweet 100's that have standard size fruit! Notice that this is the first time I'm mentioning this ... I'm not all that happy about it. I sold plants from that seed ...
The plants looked virtually all the same until they began to develop fruit. I don't know yet if this parent's fruit is worth having in the garden. I do know I have less cherries than I'd planned on.
There are accidents, everyone makes mistakes, and it usually takes 12 months to get a chance to straighten things out. Not all eggs should go in the same basket ...

I gotta tell you all about Coyote cherries! I still haven't decided how much I like the tiny guys.
Usually, I'm not delighted to pick 'n' pick 'n' pick and after 20minutes still only have a handful. Tasting one Coyote tomato, however, will give you an idea of what you are in for!
The tiny things have an incredible amount of flavor and sweetness! If you are one of those people who claim that Sungold is bland, give Coyote a try.
