Care at a glance

Light

Most houseplants will scorch where gomphrena globosa 'qis pink' thrives. Give it the windowsill you'd otherwise leave empty because everything else burned there. Full sun, 6-8 hours daily, is essential for compact growth, dense flowering and strong stems. In shade it stretches, blooms sparsely and becomes prone to disease; it tolerates the hottest, sunniest spots in the garden. A plant moved abruptly from low light to direct sun bleaches in 48 hours — always acclimatise over a week.

Watering

Aim for water deeply once a week; let soil dry between waterings for gomphrena globosa 'qis pink', but treat that as a starting point rather than a rule. A south-facing summer windowsill will dry the pot twice as fast as a north-facing winter room. Lift the pot; if it feels noticeably lighter than it did wet, water it. Highly drought-tolerant once established. Allow the top 3-5 cm to dry out, then water thoroughly. It dislikes constantly wet roots, so err toward underwatering; overwatering causes rot and limp growth.

Soil and pot

Gomphrena globosa 'QIS Pink' grows best in average, well-drained soil; tolerates poor and sandy ground. Thrives in light, free-draining soil of pH 6.0-7.0 and copes with lean, dry, sandy conditions. Rich, heavy or wet soil reduces flowering and invites rot; drainage matters far more than fertility. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Gomphrena globosa 'QIS Pink' sits happiest at around 30-50% humidity and 20-30°C (68-86°F). Prefers warm, moderately dry air with good airflow. It handles humidity better than many annuals but crowded, damp plantings can develop powdery mildew or leaf spot; space for ventilation. If you keep the room above 20 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed gomphrena globosa 'qis pink' sparingly. A light feeder. Work a little compost in at planting and apply a balanced liquid feed monthly at most. Over-fertilising, especially with nitrogen, produces floppy growth and fewer flowers; lean conditions give the best, longest-lasting blooms. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on gomphrena globosa 'qis pink' in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Powdery mildewCrowding and poor airflow bring a white coating on leaves; space plants in full sun and avoid wetting foliage.
  • Root rot from overwateringWet, heavy soil rots the roots of this drought-lover; plant in free-draining ground and let it dry between waterings.
  • Leggy, sparse blooms in shadeInsufficient sun stretches stems and cuts flower count; site in the brightest spot available.
  • Frost damageEven light frost kills this tender annual; sow or plant out only after the last frost and well into warm weather.

Propagation

Grown from seed sown indoors 6-8 weeks before the last frost or direct-sown into warm soil. Soaking seed overnight speeds germination, which takes 1-2 weeks at 21-24°C. Started annually from seed each season. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Gomphrena globosa 'QIS Pink' is pet-safe. ASPCA lists Globe Amaranth (Gomphrena globosa) as non-toxic to cats and dogs. It is a safe choice for pet households; as with any plant, eating a large amount could cause mild, short-lived digestive upset, but it poses no poisoning risk. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
