Hemerocallis 'Cartwheels' (daylily 'Cartwheels') — Clump-forming, arching foliage with upright scapes

Overview

Hemerocallis 'Cartwheels' is a clump-forming, arching foliage with upright scapes perennial in the genus Hemerocallis, part of the Asphodelaceae family, with deciduous or semi-evergreen; arching, strap-shaped, fresh green foliage. Hemerocallis 'Cartwheels' grows best in full sun to partial shade; darker colours hold better out of hot sun, and tolerates almost any reasonable soil and from loam to clay soils and acid and neutral or alkaline pH. Its UK hardiness is rated H6-H7. Suggested uses include borders, mass planting, cottage gardens and cut flowers.

About

Hemerocallis 'Cartwheels' is a clump-forming perennial daylily with arching, strap-shaped foliage and upright flower scapes. It flowers in summer, from June to August. The leaves are deciduous or semi-evergreen and a fresh green, produced in fountain-like clumps. Plant it in full sun to partial shade; darker colours hold better out of hot sun.

About the genus

A daylily, day lily or ditch-lily is a flowering plant in the genus Hemerocallis, a member of the family Asphodelaceae, subfamily Hemerocallidoideae, native to Asia. Despite the common name, it is not taxonomically classified in the lily genus. Gardening enthusiasts and horticulturists have long bred Hemerocallis species for their attractive flowers; a select few species of the genus have edible petals, while some are extremely toxic.

In the garden

Hemerocallis 'Cartwheels' is a clump-forming perennial in the Asphodelaceae family, grown for its summer display on upright scapes. Flowering runs from June to August, and the plant sets a neat mound of arching, strap-shaped leaves that are deciduous or semi-evergreen. Give it full sun to partial shade; blooms with darker tones benefit from some respite from hot sun. It will grow in almost any reasonable soil—from loam to heavy clay—and tolerates acid, neutral or alkaline pH. Aim for a moist but well drained site; once established the clumps will tolerate both damp and periods of dryness. Aspect is flexible (any), and plants handle exposed or sheltered positions. Hardiness ratings H6–H7 mean it performs in very hardy to fully hardy UK conditions. Use Hemerocallis 'Cartwheels' in mixed borders, for bold drifts in mass planting, within cottage-style beds or to supply stems for summer bouquets. Note that it is toxic to pets (cats) — consult the HTA guide to potentially harmful plants for further information and contact numbers.

Care notes

Pruning and caring for Hemerocallis 'Cartwheels'

Cultivation: Among the most forgiving of perennials, and effectively unkillable once settled. They flower most freely in an open position with reasonable moisture while the buds are forming, and benefit from division every four or five years, since a congested clump produces plenty of leaf and progressively fewer scapes.
Pruning: Snap off spent blooms to keep the display clean, and cut scapes to the base once all buds have finished. Remove dead foliage in late autumn or early spring.
Propagation: Divide in early spring or immediately after flowering, splitting the crown into fans each with roots attached. Proliferations that form on the scapes of some cultivars can be rooted as cuttings.
Pest resistance: Slugs and snails graze new spring growth, and hemerocallis gall midge distorts buds in early summer - affected buds are best picked off and destroyed.
Disease resistance: Robust. Daylily rust is the main disease of note but remains uncommon in the UK.
