Lilium 'Redmax' (Lily) — Upright unbranched stems from a scaly bulb

Overview

Lilium 'Redmax' is a upright unbranched stems from a scaly bulb bulb in the genus Lilium, part of the Liliaceae family, with deciduous; narrow lance-shaped leaves, scattered or in whorls up the stem foliage. Lilium 'Redmax' grows best in full sun with the roots in shade; some species prefer dappled light, and tolerates deep humus-rich loam and or loam-based compost in pots soils and neutral to acid and though madonna and trumpet lilies tolerate lime pH. Its UK hardiness is rated H4-H6.

About

Lilium 'Redmax' is a bulbous lily producing upright, unbranched stems from a scaly bulb and terminal large flowers. Leaves are deciduous, narrow and lance-shaped, arranged either scattered or in whorls along the stem. It flowers in the UK from June to August. Plants suit a sheltered, sunny spot where the bulb remains cool and free-draining.

About the genus

Lilium is a genus of herbaceous flowering plants growing from bulbs, all with large and often prominent flowers. Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the Northern Hemisphere and their range is temperate climates and extends into the subtropics.

In the garden

Lilium 'Redmax' belongs to the genus Lilium, a group of herbaceous bulbs native mainly to the Northern Hemisphere and temperate regions. As with other true lilies it arises from a scaly, tunicless bulb and carries narrow lance-shaped leaves either scattered or in whorls up the stem before producing terminal blooms in summer (June to August). Plant in a sunny position with the bulb’s roots kept shaded — a mulch or companion planting of lower-growing perennials will help protect the root zone. A deep, humus-rich loam is ideal; in containers use a loam-based compost. Aim for neutral to slightly acid conditions where possible, noting that a few groups such as Madonna and trumpet types will tolerate lime. Soil must be moist but sharply drained, because bulbs will rot if left in stagnant water. Choose a south-, west- or east-facing, sheltered site to avoid wind damage to the tall, unbranched stems. Lilium 'Redmax' suits the middle or back of a summer border or can be grown in large pots provided the root run remains cool and free-draining. As with all true lilies, keep plants away from cats as they are highly toxic to felines.

Care notes

Pruning and caring for Lilium 'Redmax'

Cultivation: Plant bulbs deeply, at roughly three times their own depth, on a layer of grit so water drains away from the scales; the exception is Lilium candidum, which sits just below the surface. Feed while in growth and let the stem die down naturally afterwards so the bulb can rebuild. Container growing gives the sharp drainage most lilies want and makes lily beetle far easier to police.
Pruning: Remove faded flowers to stop seed forming, but leave the stem and foliage until it has yellowed completely, then cut to the base.
Propagation: Detach offset bulbs or individual scales when dormant and grow them on in a cold frame. Species can be raised from seed, though flowering may take three to five years.
Pest resistance: Scarlet lily beetle is the serious pest and will strip a plant if unchecked - adults and larvae both need removing on sight. Slugs damage emerging shoots.
Disease resistance: Botrytis marks the foliage in wet summers. Virus, spread by aphids, causes streaked and distorted growth and cannot be cured.
