Clint, I think your plants look nice and healthy and I'm sure they'll be actively growing in no time. I've received semps in the mail with huge root systems like I've never seen on any of my plants, and some with very small roots and after planting you'd never know the difference. You've done a good job potting them up and they're all showing beautiful colors already!
I did place an order with Arrowhead but asked for delivery in April, so I can't offer any information about them from personal experience. But I'll report back when I receive my order.
Such cute babies Greg!
Good luck with your tiny ones Kate.
