Too old. No room. No way to protect from deer when they figure out I'm growing them again.
I'm not convinced origins where they are hybridized will make that much difference in many cases. Some where the lineage goes way back where the ancestors all originate in the same place - maybe. Or maybe on others where an ancestral species is heavily involved and it came from similar climate. At this point in a cultivated daylily, I'd think the gene pool has been thoroughly mixed up, so even siblings from a cross might react differently in a climate. When you look at the favorites in a region, there are some that cut a pretty wide swath across several zones and variable growing conditions. I'd think it more likely to be what genes any specific plant ended up inheriting rather than where the hybridizing takes place. Obviously, growing things in a location may be weeding out things that don't perform. I'd think that might be very local, though, and probably dependent on weather patterns which can be a long term proposition sometimes. I'm not sure a seedling selected during a long period of drought in zone 7 would like and perform the same when the weather pattern switched to something else for a few years in the same location. It might be more applicable to diploids than tetraploids. Tets are just by their very nature going to have an extremely varied and mixed up set of genetics at play. That's just my thinking on it.
