OK I chose rosettes at twenty paces for our duel Tim!
When I crossed Emerald Spring with the allionii 'Yellow-green form" I figured that was mixing up the genetics quite a bit as Emerald Spring has two different subspecies in it so these seedlings had three of the 4 subspecies. That group gave me the greatest variety of roller types of any cross I had done but they were all still rollers. I did pick out one with a bit of blue, one with leaf shape of hirtum and rosette form of allionii, one with strong purple tips, one with oddly formed leaves and one with the tiniest pointed leaves. However, because these are all smallish you have to get on your knees to see these differences.
So it is possible to get changes but I'm not sure if they are different enough to get really excited about. Worse yet, I'll have to wait four years to get flowers on these to make the next cross.
I'm normally not a pessimistic hybridizer but I do feel this is going to be a tough nut to crack. This is in stark contrast to my other lines that net really nice things without near the effort.
Agree with everyone that rollers tend to look similar but there is nothing so lovely as a spot or pot fully overgrown with them! They seem to play well together and allow growth even when they're totally on top of one another and I like that about them!
Also the lack of blooming for using in gardens and arrangements is a nice thing (i know Kevin not for you hybridizers )
Tomorrow think I have to go see how my rollers are doing
It seems the pictures all look the same now but here are a couple @goldfinch4 (i think you were who mentioned rollers in pots, can't remember)
But I like how rollers totally fill the space in a pot or confined space!
Last photo is of my semp wall, only the roller and Arach types have lives and thrive ... I'll replant
After blasting the rollers I do have one I'm excited about. A pure dark purple. First one I've seen in that color. Of course we'll see how it matures but it was one I numbered in the seedling bed last year and remarked in my notebook as "really much darker than its siblings".
