Overview

Despite the name, daylilies are not true lilies but incredibly resilient perennials whose individual flowers each last just one day — but a single plant can produce dozens of buds for weeks of continuous bloom. Nearly all parts are edible and have been eaten in Chinese cuisine for thousands of years. Be sure to eat only Hemerocallis species, as true lilies (Lilium) can be toxic.

Safety Notes

Large quantities of the leaves are said to be hallucinogenic. Blanching the leaves removes this hallucinatory component[205]. (This report does not make clear what it means by blanching, it could be excluding light from the growing shoots or immersing in boiling water[K].)
