Care at a glance

Light

Aim for at least 4-6 hours of direct sun on the leaves. Requires full sun (at least 6 hours direct sunlight daily). In partial shade the mats become loose and floriferous performance declines sharply. South- or west-facing aspects in alpine gardens are ideal. If your only bright window faces south, that's perfect for mountain everlasting — same window any aroid would fry on.

Watering

Watering mountain everlasting: every 2–3 weeks during growing season; minimal in winter. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Extremely drought-tolerant once established. Water only when the top 5 cm of soil is completely dry. Overwatering or waterlogged conditions in winter cause crown rot — the primary killer. Ensure pots have drainage holes; never allow saucers to hold water.

Soil and pot

Mountain Everlasting grows best in sharply draining alpine grit mix. Use a lean mix of 50% horticultural grit or pea gravel plus 50% loam-based compost (John Innes No. 1 or equivalent). Avoid rich, moisture-retentive potting mixes. Soil pH 6.0–7.5 (neutral to slightly alkaline suits it well). 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

Mountain Everlasting sits happiest at around 20–50% humidity and -25°C to 20°C (-13°F to 68°F). Prefers low ambient humidity, mirroring its native alpine meadow habitat. Avoid humid, stagnant air — good air circulation prevents fungal disease on the woolly foliage. Not suited to humid indoor environments. If you keep the room above 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 mountain everlasting sparingly. Fertilise sparingly or not at all. At most apply a single light top-dressing of slow-release, low-nitrogen granules in early spring. Rich feeding produces lax, disease-prone growth contrary to its natural habit. 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 mountain everlasting in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Crown rotThe leading cause of death. Caused by overwatering or poorly drained soil, especially in winter. Ensure gritty, free-draining substrate and reduce watering to almost nothing when dormant.
  • Aphid infestationWoolly stems attract woolly aphids and root aphids in warm, humid summers. Inspect the undersides of leaves and crown regularly; treat with insecticidal soap or neem oil at first sign.
  • Loss of mat density in shadeIn less than 5–6 hours direct sun, plants become leggy and rosettes spread apart, losing the tight mat form. Relocate to a sunnier position or use as a companion on south-facing slopes.

Propagation

Divide established mats in early spring or after flowering in summer — pull apart rooted rosette clusters and replant immediately in prepared gritty soil. Alternatively, sow fresh seed on the surface of gritty compost in autumn and cold-stratify over winter for spring germination. 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

Mountain Everlasting is pet-safe. Antennaria dioica is not individually listed by ASPCA. It belongs to Asteraceae and has no documented toxic principles; it is traditionally used in European herbal medicine, suggesting low toxicity risk for pets. 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.

Mountain Everlasting care — frequently asked questions

What is the common name for Antennaria dioica?

Antennaria dioica is most commonly called Mountain Everlasting, but it is also known as Mountain Everlasting, Cat's Foot, Catsfoot. The names refer to the same species, so care instructions for Mountain Everlasting apply identically to anything sold as Cat's Foot.

How much light does mountain everlasting need?

Mountain Everlasting grows best in direct sun (at least 4-6 hours). Requires full sun (at least 6 hours direct sunlight daily). In partial shade the mats become loose and floriferous performance declines sharply. South- or west-facing aspects in alpine gardens are ideal.

How often should I water mountain everlasting?

Water mountain everlasting every 2–3 weeks during growing season; minimal in winter. Extremely drought-tolerant once established. Water only when the top 5 cm of soil is completely dry. Overwatering or waterlogged conditions in winter cause crown rot — the primary killer. Ensure pots have drainage holes; never allow saucers to hold water. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is mountain everlasting toxic to cats and dogs?

Mountain Everlasting is pet-safe. Antennaria dioica is not individually listed by ASPCA. It belongs to Asteraceae and has no documented toxic principles; it is traditionally used in European herbal medicine, suggesting low toxicity risk for pets.

What USDA hardiness zone does mountain everlasting grow in?

Mountain Everlasting is rated for USDA zone 3-8 and RHS hardiness H7. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
