LOL, I geek out about this all the time!
Right now I've noticed that Lime Green Salad looks different than the other dwarfs- it is a regular leaf, but has thinner leaves than my other regular leaf dwarfs. LGS is still rugose, but has more wispy, serrated leaves than the others. Grub's Mystery Green has huge potato leaves compared to other potato leaf seedlings. Gardener's Delight is more compact than my other cherries, which are tall, leggy, and fast growing. Gardener's delight grows fast, but seems to stay shorter right now. Adorable!
They grow up so fast...
