Yellow day lily blooms in June – early July with delicate lemon-yellow and citrus-scented lily-like flowers which form a cymose inflorescence at the top of the thin flower stem. A single flower fades fast according to its name but the new ones keep appearing next to it. The long flower stems rise above the thick clump of leaves.
Yellow day lily is an easy perennial and its clumps are showy even without flowers. It can be grown in a partial shade and in Mustila it can be found from the Pähkinärinne (Hazelnut slope). In China its flower buds are eaten deep-fried and in soups.
