Light and position
Morning sun with afternoon shade is best.
Size and pot
NC State lists 3 to 4 feet; it warns the rhizomes can grow big enough to split a container. Our pot band: large pot (more than 15 litres).
Watering
NC State says a container plant needs a lot of water.
Potting mix and feeding
Moist, well-drained mix.
Growing through the year
Divide rhizomes to plant. NC State notes that in India it goes dormant after the monsoon; harvest when the leaves begin to wilt and dry.
Winter outdoors
Cold limit: not given by our source. NC State lists USDA zones 8 to 11, which describe dormant rhizomes in the ground, and suggests lifting the rhizomes in autumn and storing them in a cool, dry place where it is not winter hardy. That figure does not apply to a pot, so we give no outdoor winter limit: protect it from cold, or lift and store the rhizomes.
| Your coldest winter nights | What to do |
|---|---|
| Coldest nights 15 °C or warmer | Cold limit not given by our source: protect from cold |
| Coldest nights 10 to 15 °C | Cold limit not given by our source: protect from cold |
| Coldest nights 5 to 10 °C | Cold limit not given by our source: protect from cold |
| Coldest nights 0 to 5 °C | Cold limit not given by our source: protect from cold |
| Light frost: nights down to about −5 °C | Cold limit not given by our source: protect from cold |
| Hard frost: nights below −5 °C | Cold limit not given by our source: protect from cold |
A plant can stay out only when its limit is below the coldest night in your band; a limit equal to that night counts as needing shelter. A rare cold snap, wind or a wet pot can still damage plants. We convert °F to °C with NIST’s formula.
Watch for
Red spider mites on older plants or dry soil; slugs and snails on young leaves. The yellow dye stains and can irritate skin.
Pets and people
We did not find an ASPCA entry, and NC State gives no pet rating, so pet safety is not confirmed.
General gardening information, not professional advice. Plant toxicity details are a starting point, not veterinary or medical advice: if a pet or child may have eaten a plant, contact a veterinarian or doctor promptly.
Care level: NC State’s maintenance rating (Medium). Pot band and summary wording are ours, based on the sources below.
