Hemerocallis 'LONGFIELDS MODEL' daylily

Longfields Model is an attractive tetraploid daylily from the Dutch Longfields series, introduced in 2021, with large flowers approximately 18 cm across. The base colour is a deep purplish wine, complemented by a lighter slate‑pink watermark above a green throat. The petals are firm, broad, with smooth margins and a velvety surface that enhances the richness of the colour. It flowers in the midseason and is a reblooming type, capable of producing a second flush later in summer. Scapes reach around 80 cm and carry many buds, ensuring an even and extended flowering period. The foliage is grass‑like, deciduous to semi‑evergreen.

The Longfields series originates from the Dutch nursery Heemskerk, which has been working with daylilies since 1965. It is one of the traditional European producers focused on large‑flowered, strongly coloured and garden‑reliable cultivars. Their work is characterised by robust plant habit, saturated colours and cultivars suitable both for mass plantings and for home gardens. The American Daylily Society, which maintains the official cultivar registry, lists an impressive 43 cultivars from this series by 2026, including both diploid and tetraploid introductions.

Daylilies thrive in full sun or light partial shade and grow best in deeper, fertile, well‑drained yet consistently slightly moist soils. Thanks to their fleshy roots (rhizomes) they tolerate even prolonged dry periods without damage. They flower most abundantly in sunny positions and when clumps are divided every four to six years, which maintains vigour and prevents congestion in the centre. After flowering, the foliage of some cultivars may look tired, so it is advisable to remove the entire spent scapes and, when needed, the oldest or damaged leaves to maintain a clean appearance and encourage further blooming. Young shoots can be attractive to small shelled slugs, which slightly damage them visually, particularly in moist spring weather. The roots are very hardy in the ground and overwinter reliably even in severe winters; most cultivars tolerate temperatures down to around –40 °C (USDA zone 3). In containers they perform well only in sufficiently large pots with quality substrate, regular watering, feeding and protection from summer overheating, otherwise they dry out quickly and reduce flowering. They are long‑lived, reliable, undemanding and generally free from serious pests and diseases.
