Hemerocallis Stella d'Oro

Hemerocallis is the botanical name for daylilies, long-lived herbaceous perennials with strap-like foliage and large summer flowers. They are not true lilies, despite their common name, and are easy to grow in borders or large containers.

Each individual daylily flower usually lasts for just one day, which is where the name comes from. However, each plant produces several flower stems with many buds, so fresh flowers open in succession for weeks.

Hemerocallis grows best in full sun, in fertile soil that is moist but well-drained. It will tolerate partial shade, but plants in sunnier positions usually produce more flowers.

The most common causes are too much shade, dry soil during growth or an overcrowded clump. Move or divide congested plants in spring or autumn, water during dry spells and give them a sunnier position for the best display.

Yes. Daylilies are hardy perennials that die back in winter and return each spring. Cut back the spent flower stems once flowering has finished, and divide established clumps every few years if they begin to flower less well.
