Elettaria cardamomum

Cardamom from the forests of southwestern India

Elettaria cardamomum is native to southwestern India and produces the green cardamom spice. Carl Linnaeus first named it in 1753 under Amomum, and Francis Maton published the current Elettaria name in 1811. Centuries of cultivation carried its aromatic seed capsules far beyond their native range.

In the Western Ghats, cardamom grows in the sheltered lower layers of tropical forest. Leafy shoots rise from spreading underground rhizomes, with flowering stems developing close to the ground. Warm humid air, monsoon rain and light filtered through taller trees are followed by a drier season. Its broad leaves emerge from deep, organic forest soil.

Care for broad-leaved tropical growth

Height control and leaf care

Give the upright clump enough room to stand naturally. Cut a yellow or damaged pseudostem at the soil line after its leaves decline; new shoots arise from the rhizome, and shortening healthy stems does not make them branch.

Humidity and airflow

Ordinary room humidity can sustain the plant if root moisture is even, but moderate to high humidity improves the long leaf margins and unfolding shoots. Provide gentle circulation through a dense clump so the pseudostem bases do not remain still and damp.

Light

Place cardamom close to an east- or north-east-facing window, or a short distance from brighter south or west glass with hot sun filtered. Insufficient light produces thin leaning stems, wide spacing and little new growth from the rhizome.

Watering

Keep the root ball evenly moist during active leaf and shoot production. The shallow rhizome and dense fibrous roots lose leaves after prolonged dryness, yet stagnant saturated substrate deprives them of oxygen.

Fertilising

Feed a vigorously growing clump with balanced fertiliser at a modest dose occasionally while growth is active. Reduce when new growth slows.

Repotting

Repot when rhizomes press against the wall, roots densely fill the pot, watering becomes unusually frequent or the mix compacts. Lift the clump by its root ball, loosen only the crowded outside and return the rhizome to surface level.

Cardamom leaves indoors: common setbacks

• Leaf edges and tips turn brown: The underground stems and roots have probably dried unevenly or accumulated salts from feed or hard water. Keep the mix evenly moist but drained, flush it periodically and move the foliage away from hot dry airflow.
• Tall leaves roll inward and droop: Check the root zone immediately. A dry pot needs a thorough soak; if it is already waterlogged, inspect for damaged roots before watering again.
• One old leafy shoot yellows while new shoots stay green: Individual shoots age and can be cut at soil level once fully yellow. Multiple young shoots collapsing from a soft, sour-smelling base indicate rot in the underground stem instead.
• Fine pale speckles spread over the long blades: Spider mites can build quickly in warm, dry rooms. Inspect beneath the leaves for webbing, isolate the pot and use repeated treatment from our spider-mite guide
• The plant makes leaves but no cardamom pods: This is normal indoors. Flowering and fruiting require mature plants and sustained tropical conditions, so grow it primarily for its aromatic foliage; indoor flowering and seed production are uncommon.

Keep Elettaria cardamomum away from children and pets

• Keep this plant away from children, cats and dogs.
• Its effects after chewing or swallowing are unclear, and plant material can still cause an upset stomach.
• Contact a veterinarian or medical professional if symptoms develop or do not settle.

About the name Elettaria cardamomum

Elettaria preserves an old South Indian name used for cardamom. The epithet cardamomum is the botanical Latin form of an ancient Greek name for cardamom.

William George Maton established the genus Elettaria in 1811 in Transactions of the Linnean Society of London, volume 10, page 250.

Carl Linnaeus first described it as Amomum cardamomum in 1753 in Species Plantarum, page 1. William George Maton later placed it in Elettaria as Elettaria cardamomum in 1811 in Transactions of the Linnean Society of London, volume 10, page 254.
