Annual everlasting

Xeranthemum annuum

In other languages: Xeranthemum (Nederlands) · Xéranthème annuel (Français)

Annual everlasting is a paper-flowered annual from southern Europe and western Asia. It forms straight, branching stems of 50–70 cm with narrow, silver-grey, slightly woolly leaves. From July to September it bears daisy-like flowers in pink, purple and white, sometimes double. The papery ‘petals’ are in fact dry bracts, so the flowers already look dried on the plant. That makes it a classic for dried bouquets and a good choice for sunny, dry, poor soil.

Identify

Annual everlasting: how do you recognise it?

Habit
Upright, branching annual 50–70 cm tall and about 30 cm wide.
Leaves
Narrow, lance-shaped, silver-grey and slightly woolly.
Flower
Daisy-like flowers 2–4 cm across with papery bracts, from July to September.
Colour
Pink, purple and white; double forms exist too.
Roots
Taproot: it dislikes being moved, so sow in place or in separate pots.

Flowering: July–September · Sowing: March–May · Plants: May

In your garden

Why grow it?

  • Papery flowers from July to September that stay beautiful for years when dried.
  • The everlasting flower par excellence: pick, hang upside down and make bouquets.
  • Loves sun and poor, dry soil where many other summer flowers fail.
  • Bees visit the flowers.
  • Silver-grey foliage gives a soft, airy look in the border.

Annual everlasting: where does it grow best?

  • Full sun: the sunnier, the better the flowering.
  • Well-drained, poor sandy or loamy soil, neutral to chalky.
  • Dry: it tolerates drought very well, but not wet soil.
  • Allow 20–25 cm between plants; in windy spots support with twigs or netting.

Goes well with

  • Strawflower: Another everlasting in the same dry, sunny soil.
  • Baby’s breath: Clouds of small white flowers among the papery blooms.
  • Lavender: Scented leaves and blue spikes in full sun.
  • Globe thistle: Blue globes that dry well too.
  • Feather grass: Soft plumes that move in the wind.

Maintenance

Annual everlasting: when and how to plant it?

Plant in May.

  1. Sow indoors in March in separate pots, or in April–May where it is to grow, once the soil no longer freezes.
  2. Sow shallowly (about 0.5 cm) in loose, well-drained soil; it germinates in 1–2 weeks at about 18 °C.
  3. Plant young plants out in May, 20–25 cm apart, in a sunny, dry spot.
  4. Keep the rootball intact when removing it from the pot, as the taproot dislikes disturbance.
  5. Water in at once; after that only in long dry spells.
  6. If you sow in place, sow in rows and thin the seedlings later to 20–25 cm.

Care

Water
Little: only in the first weeks and in extreme drought. Too much water gives floppy plants and rot.
Feeding
Not needed. On rich soil it grows floppy and falls over easily.
Support
In windy spots, a few twigs or netting keep the stems upright.
Deadheading
Remove faded flowers or pick them for bouquets: new buds keep forming.
Harvesting for drying
Pick the flowers just as they open, tie them in bunches and hang them upside down in an airy, shady place.

Tip: Sow in April–May where it is to grow, in a sunny, dry spot. Pick the flowers just as they open and hang them upside down: they stay beautiful for years.

Annual everlasting: when to prune it?

When: It is not pruned. Pick or cut the flowers during flowering.

How:

  • Pick the flowers just as they open, with a long stem, for bouquets or for drying.
  • Cut off faded flowers for longer flowering.
  • After the first frost, pull up the whole plant.

Pruning calendar and basic rules

Propagation

Sowing indoors
In March in separate pots with seed compost; sow shallowly, germination in 1–2 weeks at about 18 °C. Plant out after mid-May.
Sowing in place
In April–May in a sunny, dry spot, shallowly and in rows; thin to 20–25 cm.

Annual everlasting: how does it get through the winter?

Hardy to −5 °C: protect in harsh winters.

  • An annual: after flowering or the first frost the plant dies.
  • Young plants tolerate light frost down to about −5 °C, but it does not survive hard winters.
  • Seed left on the ground in autumn may come up in spring; or collect seed and keep it dry.

Diseases and pests

  • Rot: Too much water or a wet summer rots the stem base. Sow in dry, well-drained soil.
  • Floppy growth: On rich soil or in partial shade it grows tall and floppy. Plant in full sun in poor soil.
  • Slugs: Young seedlings are eaten. Use iron phosphate pellets or sow slightly thicker.
  • Aphids: On young shoots. Rinse with water or let ladybirds do their work.
  • Powdery mildew: White powder in a humid, close summer. Leave space between plants and cut off affected parts.

Through the year

  • March: Sow indoors in separate pots.
  • April: Sow in place once the soil no longer freezes.
  • May: Plant young plants out. Sow in place.
  • June: Weed. Thin seedlings.
  • July: First flowers. Pick flowers for drying.
  • August: Full flower. Keep picking.
  • September: Last flowers. Collect seed.
  • October: Clear the plants after the first frost.

Use
