Main use: Farmers mostly grow this crop for fresh and dried shoots for seasoning, herbal teas, medicinal extracts and essential oils..

Pollination: This crop is mainly pollinated by insect. Keeping flowers healthy and having insects like bees in the field helps improve fruit set and yields.

Where it grows: Mediterranean origin; suited to warm temperate to subtropical climates with good drainage. It is grouped under: Spices & Condiments.

Best climate: This crop does well in warm areas where the temperature is usually between 15 and 28 degrees Celsius. It prefers places that receive around 500 to 900 millimetres of rain in a year. It can grow from near sea level up to about 2300 metres above sea level.

Soil: The crop grows best in slightly acidic to near neutral soils, with a pH of about 6 to 7.5. It does well in well-drained sandy loam or loam; tolerates relatively poor soils if drainage is good.. Good drainage is important, so avoid waterlogged spots.

Plant spacing: Plant in rows about 70 centimetres apart, and leave about 50 centimetres between plants in the row. This gives each plant enough space for roots and canopy to spread.

Planting depth: Dig planting holes or furrows about 3 centimetres deep so the roots sit firmly in the soil but are not buried too deep.

Seed or planting material: Use good quality seed or healthy planting material. Follow local extension advice for the exact amount per hectare.

Nursery period: If you raise seedlings in a nursery, keep them there for about 35 days before transplanting to the main field, when they are strong and healthy.
