In my garden I grow a double orange variety passed along to me by my aunt, and a green-throated red variety, 'Pardon Me,' that I bought at a discount store. A frilly unnamed variety grows next to the common orange daylily out front by our sentry light.
Daylilies bloom as they are named: each blossom opens in the morning and closes the same night, then it is finished. Plentiful new blooms show daily for a few weeks--a nice, steady show. Grassy green foliage provides a lush filler for the flower bed for the remainder of the season.
Any plant that can do all that--with no care whatsoever on my part--gets a thumbs up from me. Daylily photo by JulenaJo.
