robinjoy said:I have been thinking that with your interest in white gardens you might start wondering about white daylilies. Daylilies do not approach the whiteness of many other species; most are actually a very pale yellow or have a faint peach cast. A group of us have been working on cataloguing the whiteness into five groups, with none making it into group 1, pure white. Since you are likely not a member of ADS, I don't think you have access to the recently published study (author is Stuart Kendig). If you are on Facebook there is a private group that discusses white daylilies that Stuart admins, and I am sure he would let you join if you sent a request.
The benchmark group 2 ("bright white") daylilies are Gentle Shepherd and Sagarmatha. There are some recently introduced ones that are falling into this group, but they are generally hard to find or quite expensive still.
Group 3 ("comparably white") includes favorites like Joan Senior.
Group 4 ("near white") includes Early Snow, which I see on your plant list, Margo Reed Indeed, and Ice Carnival, a nice historic one which is registered as very fragrant.
Group 5 ("white blend") includes lots of daylilies, such as Peggy Jeffcoat which you may have seen discussed on another thread recently.
Does anyone know if "white" daylilies are a little more fragile (as some white flowering plants are) and more prone to rust????

Here it is with some Shasta Daisies in the background, so you get an idea how far away from white those Group 4 near white daylilies can be.
