Hemerocallis are commonly known as daylilies as their individual flowers last only one day.

These exotic flowers are ideal for sunny borders and the foliage is often evergreen in milder locations. There are thousands to choose from in a range of colours, from white through yellow to deep red and burgundy. Hemerocallis are easy to grow, produce blooms for weeks on end, that make good cut flowers as well as being attractive to native insects, particularly hoverflies and ladybirds. And, if you’re willing to try, some hemerocallis varieties are considered to be an edible delicacy – fried or added to salads.
