It does depend on what you grow. I've had the species Hemerocallis minor in flower since some time in May. There's a yellow daylily in gardens locally that I think is Hemerocallis lilioasphodelus, and it's in flower. 'Flavina' has flowers open, so does a NOID that may be 'Gold Dust'. There are scapes on 'Pawprints on my Heart' (my avatar), 'Siloam June Bug', 'Bee's Bettie Sue', Hollywood Daily' and at least a couple of others that I'd need to check their ID on a map. It's raining out and tons of mosquitoes so I haven't been out to look today.
