Cardamom
Amomum
Overview
Known as the queen of spices, cardamom is a tropical plant in the ginger family that produces intensely aromatic seed pods. It is the third most expensive spice in the world after saffron and vanilla, treasured for its complex warm-cool flavor profile. In its native habitat of India's Western Ghats, cardamom grows in the shaded understory of tropical forests.
Growing Conditions
How to Grow Cardamom
Cardamom (Amomum) is a forb/herb that grows to about 5 feet tall and 5 feet wide.
To grow cardamom, give it partial sun to partial shade. It is hardy across USDA hardiness zones 8–12. Plant it in rich, moist, well-drained forest soil or humus, at a slightly acidic pH of 5.5–6.5. It does best with even, moderate watering.
In practice, plant out cardamom April to May in warm zones and March to April in hot zones. Harvest comes October to December in warm zones and September to December in hot zones. Old knowledge lives in this one; grow it, and you keep a little of that alive.
Companion Planting & Soil
Cardamom grows well alongside ginger, turmeric, banana, and coffee.
