Overview

Hemerocallis 'Marion Vaughn' 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 'Marion Vaughn' 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.

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 'Marion Vaughn' sits in the Asphodelaceae as a clump-forming perennial with arching, strap-like leaves and flowering scapes. Its blooms are scented and appear in the summer months between June and August. Foliage can be deciduous or semi‑evergreen depending on location. Grow it in full sun to partial shade; darker flower colours hold up better when given some relief from hot, direct sun. It tolerates almost any reasonable soil from loam to clay and accepts acid, neutral or alkaline pH. Aim for a moist but well-drained site — the plant will cope with both damp and drier situations once established. Aspect is not critical and the daylily will tolerate exposed or sheltered positions. Rated H6–H7 (very to fully hardy) for UK conditions. Use Hemerocallis 'Marion Vaughn' in mixed borders, for mass planting, in large containers or as a source of cut flowers. The arching, fountain-like leaves provide a clear structural base beneath the upright scapes, so grouping plants emphasises that architectural contrast and gives the clump presence through the summer months.

Care notes

Pruning and caring for Hemerocallis 'Marion Vaughn'

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.
