Nice thing about LA is time can be taken to check out lineage to see if there is rust resistance or not.
In seeds, rust resistance may or may not come through, but I'm buying ones with rust resistant backgrounds.
I'm tagging seedlings with rust resistance ratings and those that aren't won't be included in my crosses.
With 77,000+ registered daylilies, hybridizing options shouldn't be limited.
I hate spraying too.
