Elettaria cardamomum (cardamom) 9cm pot

Growth habit & appearance: Elettaria cardamomum forms dense clumps of smooth, upright, cane-like stems with broad, lanceolate leaves that release a warm, resinous aroma when brushed. Its layered foliage and tropical architecture make it an attractive specimen plant, while mature clumps produce flower spikes at the base that carry pale, intricately marked blossoms.

Growing conditions: This species is fully tender in Ireland and must be protected from cold nights and early frost. It thrives in part shade to full shade, mirroring its natural habitat in the understory of humid Asian forests. Grow in a warm conservatory, heated glasshouse, or moveable pot so it can be brought indoors for overwintering. Consistent moisture, high humidity, and a rich, compost-amended substrate are essential for strong growth in Ireland’s cooler climate.

Traditional & herbal uses: Traditionally associated with easing digestive discomfort including intestinal gas and symptoms linked to IBS. It has historical use for coughs and bronchitis, and is noted in some traditions for supporting oral hygiene.

Maintenance & harvesting: Keep the soil evenly moist, never allowing it to fully dry out. Mulch the surface annually with compost to maintain fertility and moisture retention. In container culture, divide established clumps to prevent overcrowding and encourage fresh, vigorous stem production. Bring plants indoors before temperatures fall below 10°C. Flower spikes, if produced, emerge low on the plant—avoid disturbing the base when weeding or repotting. Harvest any usable material sparingly to maintain plant strength.
