ASPCA advises it is very Toxic to Cats. Does not appear to be so with dogs-horses.

Planted this plant 17 years ago between 2 Colorado Blue spuce. Trees engulfed it completely thought it was gone, then saw a little bit of daylily leaves spring '06; dug it up, divided it and replanted. Had a very low bud count spring '07. The 3 small divisions became a stately clump in a year. Worth having for the foliage, and red flower buds/stems. Foliage makes nice mounded shape and turns a nice yellow for short time in fall, after most daylilies leaves are brown and withered.

I 've saved this daylilly from refuse dump...someone had just thrown her away.. she looked really bad and I could hardly recognize her as a daylilly. I 've taken her home and planted her in my garden. After two years she rewarded me with only one bloom...but so lovely and with such a pretty scent. Since than, every mid spring, it flowers lovely and abundant ...looking good and healthy. I have'nt seen a garden where it is I 'm still wondering from which garden she came from..Well...she sure is special for me... H. dumortieri comes original from Japan, Korea, Manchuria en East-Siberia. In 1830 it is introduced in Netherlands by Von Siebold.
