Crossandra infundibuliformis 'Mango' (Mango firecracker flower) care

Light

Bright but filtered. Crossandra infundibuliformis 'Mango' burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Bright, filtered light or partial sun. It blooms best with several hours of gentle sun but dislikes harsh, hot midday rays, which can scorch leaves and shorten flower life. If you only have a south window, set the plant back 1.5 m or hang a sheer curtain — both knock the intensity down into the right range.

Watering

Watering crossandra infundibuliformis 'mango': when the top 2 cm of soil is dry, roughly every 3-5 days in warmth. 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. Keep soil evenly moist while in flower; it resents both drying out, which drops buds, and soggy soil, which rots roots. Use tepid water and reduce frequency in cooler conditions.

Soil and pot

Crossandra infundibuliformis 'Mango' grows best in rich, well-drained potting mix. Fertile, organic, free-draining soil suits it best. In containers use a peat-free mix with compost and perlite; slightly acidic to neutral pH gives healthy, deep-green foliage. 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

Crossandra infundibuliformis 'Mango' sits happiest at around 50-70% humidity and 18-29°C (64-84°F). Prefers moderate to high humidity; dry indoor air causes leaf-tip browning and bud drop. A humidity tray, grouping, or a humid conservatory keeps it flowering freely. If you keep the room above 18 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 crossandra infundibuliformis 'mango' sparingly. Feed every 2 weeks through the growing season with a balanced or bloom-promoting liquid fertiliser to sustain continuous flowering. Dilute to half strength for potted plants and reduce in winter. 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 crossandra infundibuliformis 'mango' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Bud and flower drop — Triggered by drying out, cold draughts, or sudden moves. Keep moisture and temperature steady and avoid relocating it while budding.
• Yellowing lower leaves — Often overwatering or cold roots. Let the surface dry slightly, use tepid water, and keep it warm above 15°C.
• Spider mites in dry air — Low humidity invites mites that stipple and bronze leaves. Raise humidity, rinse foliage, and treat with insecticidal soap if they persist.
• Leggy, bloom-poor growth — Too little light or feed stretches the plant. Move to brighter filtered light and feed regularly to restore compact flowering.

Propagation

Propagate from softwood stem cuttings in spring or summer, rooted in warm, humid conditions; the cultivar must be grown from cuttings to stay true. Species plants can also be raised from seed. 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

Crossandra infundibuliformis 'Mango' is mildly toxic to pets. Crossandra infundibuliformis is not individually listed on the ASPCA's toxic or non-toxic plant database, and the genus Crossandra is unlisted. Without authoritative ASPCA non-toxic confirmation, treat it as uncertain and potentially mildly toxic; keep it away from pets and consult a vet if any is chewed or swallowed. 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.
