Kidfishing - don't get TOO excited. The reality is that over 90% of hosta seedlings will be unexciting green plants. BUT, you can get surprises. And if you like a seedling, keep it and assess it for at least 5 years. I have a few that I wavered back and forth on whether to keep for several years. If you grow enough, the chances of getting plants you want to keep increases too.
These are some of the seedlings I've kept and/or am watching. All are OP.
'Amy's Choice' - a 2007 seedling of 'Korean Snow'. It actually looks like several later seedlings I've had from KS, but this one was the first and initially it seemed a bit misty. It's nothing really special though. Named after one of my granddaughters.
'Dancing With Leila' - a 2008 seedling of 'Last Dance' that is a rare variegated seedling from a non-streaked plant. It is reverse variegation from its parent and looks nearly identical to 'Dance With Me', hence its name in honour of one of my granddaughters.
'Lovely Leila' - a 2006 seedling of unknown origin - the squirrels moved its marker the first winter. It emerges quite light in the leaf centre and gradually gets a dark misty colour. Named after one of my granddaughters.
A 2006 seedling of 'September Sun'. It's obviously not going to be a large plant, but it keeps its yellow colour well. I think I'm going to call it 'Golden Nolan' in honour of my grandson.
A very tiny 2012 seedling from 'Lemon Frost' that I rather like.
A 2013 seedling from 'Fire Island'
A 2013 seedling from 'Neat Splash'. A friend shared the seeds with me. I think there are several degrees of streakiness going on here and I think I will dig the plant and separate the various eyes so that I can watch them better. So far, it's interesting and I may name one of them after my other granddaughter Heidi - maybe something like 'Happy Heidi' (unless someone has a better idea). BTW, best not to name a seedling after a family member until you are sure you like the seedling.
A 2013 seedling from 'Spilt Milk' which has a narrow margin. This could eventually be a fairly large plant, I think.
A 2013 seedling from 'Touch of Class' that has nice red legs.
A nice blue seedling - 2010 from 'Déjà Blu'.
