Pink Mulla Mulla

Ptilotus exaltatus

The Story

Plant Bio

Ptilotus exaltatus is an upright, short-lived herbaceous perennial native to the arid interior of Australia, characterized by a basal rosette of fleshy, blue-green foliage. In summer, it produces dense, conical flower spikes up to six inches long, covered in feathery, silver-pink bracts with prominent magenta tips.

The species is highly adapted to low-nutrient, sandy soils and extreme heat, making it an exceptional choice for dry containers or gravel gardens. Its succulent-like leaves store moisture, allowing the plant to withstand prolonged dry spells once its root system is established.

Uses & Benefits:

Ornamental UsesProduces striking, long-lasting feathery pink flower spikes that contrast with glaucous, blue-green foliage.
Practical UsesHighly drought-tolerant and well-suited for low-water landscaping, containers, and cut flower arrangements.
Ecological BenefitsAttracts generalist insect pollinators and bees to its nectar-bearing flowers during the heat of summer.

Planting

How to Grow

  1. Select a planting site that receives at least six to eight hours of direct sunlight daily.
  2. Amend the planting area with coarse sand, fine gravel, or perlite to guarantee rapid drainage.
  3. Settle the plant into the soil, keeping the crown slightly elevated above the surrounding soil level to prevent moisture accumulation.
  4. Water thoroughly immediately after planting, then withhold water until the top two inches of soil are completely dry.

Pro Tip

Treat this species like a desert succulent: plant in a lean, gritty mineral mix, maximize air circulation, and allow the potting medium to dry out completely between waterings to prevent root rot.

Care Guide

Do

  • Grow in unglazed terracotta pots to facilitate soil drying through evaporation.
  • Deadhead spent flower spikes cleanly at the base to stimulate subsequent blooms.
  • Provide wide spacing between plants to maximize air movement and reduce humidity levels.

Don't

  • Do not use organic-rich composts or heavy clay soils that retain moisture.
  • Never water overhead; wet foliage in stagnant air quickly triggers fungal diseases.
  • Do not cut back into old, leafless woody stems, as they will not regenerate.
