Next is a true white daylily, 'Gentle Shepherd.' I think this may be the whitest daylily available. 'Ice Carnival' and 'White Formal' both have an underlying yellow tint. 'Gentle Shepherd' can be variable with its flower form, but it remains my favorite white (until you ask me next time.)
'Sunday Gloves' is another nice white daylily, although not quite as pure as 'Gentle Shepherd' it probably has a more consistent form.
'Holiday Delight' makes a bright and bold statement in the garden.
And I will end with 'South Seas' which has an unusual bright coral/tangerine coloration.
