Mostly a combination of obsessive, lucky and having the time and space to grow a lot of plants.
The Blue Green Zebra that I found last year from Tom Wagner's Blue Green was interesting and unique so I grew out a dozen plants of it this year. Last year it was a salad size, this year I have a couple of plants showing what look to be bigger fruits.
I've got about 50 plants of various woolly lines this year. This one is Tigerpillar from Tom Wagner.
Quite a few of the woolly plants are derived from Tom's Seattle Woolly Blue Mammoth, this one is a selection I got from Heritage. It has woolly foliage, fuzzy skin, stripes and antho.
Unfortunately a few plants aren't tagged in the field. I believe this is also from SWBM, but I'm not sure of the seed source. It's similar to the one above, but the striping pattern and fruit set is different.
