Pontederia cordata 'Pink Pons' (Pink Pickerelweed) care

Light

Pontederia cordata 'Pink Pons' needs sun on the leaves, not just bright ambient room light. Full sun gives the best pink colour and most spikes; tolerates a little shade with reduced flowering. Aim for six or more hours of direct light. A south or west-facing windowsill in the northern hemisphere is the default; anywhere else, expect the plant to stretch and pale out within a season.

Watering

Water pontederia cordata 'pink pons' keep in standing water year-round. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Grow with 5-20 cm of water over the crown at a pond margin or in saturated bog soil; this compact form suits shallower planting but must stay wet.

Soil and pot

Pontederia cordata 'Pink Pons' grows best in heavy, fertile aquatic loam or clay. Use dense aquatic compost or clay-loam in a basket and topdress with gravel; rich substrate keeps the pink spikes coming. 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

Pontederia cordata 'Pink Pons' sits happiest at around Ambient outdoor humidity and -23 to 32°C (-9 to 90°F). An outdoor marginal aquatic indifferent to air humidity; warm shallow water and fertile mud are what count. 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 pontederia cordata 'pink pons' sparingly. Feed container plants with an aquatic fertiliser tablet in spring and midsummer; avoid loose feed that clouds the water and promotes algae. 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 pontederia cordata 'pink pons' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Paler colour in shade — Insufficient sun mutes the pink and reduces flowering; site in full sun for the strongest colour.
• Reversion in seedlings — Self-sown seedlings may not keep the pink colour; remove off-type seedlings and propagate by division to maintain the cultivar.
• Leaf-chewing pests — Beetles and borer larvae graze the foliage; pick off heavy infestations and accept minor cosmetic damage.
• Wilting if dried out — Drying of the rootzone triggers rapid collapse; maintain standing water or saturated mud throughout the season.

Propagation

Divide the rhizomes in spring, replanting shooted pieces into wet aquatic soil; propagate by division rather than seed to keep the pink flower colour. 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

Pontederia cordata 'Pink Pons' is mildly toxic to pets. Pontederia cordata and its cultivars are not individually listed by the ASPCA. The species is recorded as historically human-edible when cooked, but that does not establish pet safety; treat with caution and verify with a vet before assuming it is safe for cats or dogs. 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.
