Sneezeweed 'Moerheim Beauty'

Sun

Full sun; flowering is weaker and stems are more likely to lean in shade.

Water

Keep evenly moist, especially during establishment and flowering. Water deeply during dry spells; this is not a drought-tolerant border plant.

Soil

Fertile, moisture-retentive soil with good drainage. Loam and improved clay suit it well; avoid dry sand and soil that stays waterlogged in winter.

Height

3-4 ft (0.9-1.2 m)

Spread

1.5-2 ft (0.45-0.6 m)

Flowers

Early summer to early autumn, depending on climate; copper-red to reddish-brown petals often develop orange or yellow tones as they age, around prominent dark brown centres.

Foliage

Green, lance-shaped leaves on upright, branching stems; the above-ground growth dies back for winter.

Growth

Moderate to fast; forms a substantial flowering clump within two or three growing seasons.

Growth rate

Fast

• Water at soil level during dry weather, before the root zone dries out completely.
• Apply compost in spring; avoid heavy nitrogen feeding, which encourages floppy growth.
• Mulch with compost or leaf mould to conserve moisture, keeping it clear of the crowns.
• Install discreet supports in spring in exposed sites or rich soil.
• Divide congested clumps every two to three years in spring, replanting vigorous outer sections.

Pruning. Remove faded flower heads down to a leafy side shoot to encourage further flowering. Cut dead stems close to ground level in late winter or early spring before new shoots extend.

Early spring

Cut down remaining dead stems and check emerging shoots for slug damage.

Spring

Plant or divide clumps, water thoroughly and apply a moisture-conserving mulch.

Late spring

Fit supports before stems become tall and difficult to gather.

Summer

Water deeply in dry spells and remove faded flower heads regularly.

Early autumn

Continue deadheading while flowers are forming, or leave the final heads for seed and structure.

Late autumn

Leave sound stems standing if wanted for winter habitat; remove diseased material.

• Plant in small groups through the middle of a sunny mixed border for repeated copper-red colour.
• Combine with ornamental grasses for a loose, late-season planting with contrasting flower and leaf shapes.
• Use in a hot-coloured border with yellow, orange and purple flowers.
• Include in a cutting garden with reliable irrigation and access for picking.

Garden styles it suits: Cottage garden, English country, New perennial (prairie), Hot border, Pollinator garden and Arts and Crafts.

Plant it with: Black-eyed Susan, Garden phlox, Bee balm, Purple coneflower, Switchgrass and Feather reed grass.

Wildlife: The open flower heads provide pollen and nectar for bees, hoverflies and butterflies. Standing stems offer shelter for small invertebrates over winter.

• Slugs and snails can eat emerging shoots: inspect in damp weather, remove hiding places and use wildlife-conscious controls where needed.
• Powdery mildew may coat leaves in dry or crowded conditions: maintain root moisture, improve spacing and remove badly affected foliage.
• Dry soil causes wilting, scorched leaves and a shortened flowering season: water deeply and mulch the root zone.
• Stems may flop in shade, exposed positions or overly rich soil: grow in full sun, avoid excess feeding and provide early support.

Treat all parts, especially flowers and seeds, as toxic if eaten by people, cats, dogs or horses. Ingestion can cause digestive upset; substantial consumption can cause serious poisoning, particularly in livestock. Sap or plant contact may irritate sensitive skin, so wear gloves when handling.

• Black-eyed Susan (Rudbeckia fulgida)

  Usually has golden-yellow petals rather than copper-red ones. Sneezeweed has a more rounded central dome and petals with conspicuously notched tips.

• Purple coneflower (Echinacea purpurea)

  Has a stiff, prickly central cone and typically pink-purple, narrow, drooping petals. Sneezeweed has shorter, broader, notched petals and a rounded button-like centre.

The common name sneezeweed comes from the historical use of dried, powdered leaves as snuff to provoke sneezing, not from a particular tendency to cause hay fever.

Propagation. Divide in spring or take basal shoot cuttings in spring. Seedlings do not reliably retain the characteristics of 'Moerheim Beauty'.
