How to Start It
★ Recommended for beginners
Lift a clump in spring or autumn, pull or cut it into fans each with roots, and replant — fast, free, and almost foolproof.
One of the toughest, most forgiving perennials going — it shrugs off heat, drought, poor soil, sun or part shade, and pests. Each flower lasts just a single DAY (hence the name), but a healthy clump throws so many buds it blooms for weeks. Clumps bulk up fast and are easily split to make more or share. (Some daylilies are edible, but enjoy them here as a no-fuss flower.)

Growing Tips
- 1Plant in full sun (they tolerate part shade but flower less) in almost any soil, water while establishing, then largely forget them — they're a brilliant low-maintenance filler for tough spots and slopes.
- 2Deadheading and removing seed pods keeps them looking neat and pushes more buds.
- 3Choose reblooming varieties for the longest show, and divide congested clumps to multiply your stock.

Harvesting
When to Pick
Each bloom lasts a day, but a clump flowers for weeks through summer
How to Harvest
- 1Daylilies need very little: snap off the spent daily flowers and the bare seed pods to keep them tidy and blooming, and cut the whole flower stalk (scape) at the base once it's finished.
- 2Tidy away dead foliage in late autumn.
- 3Divide every few years to keep them vigorous and floriferous.
- 4That's genuinely all.
