Seed is most commonly collected by hand. Fruiting heads can be cut from stems using shears or a hand scythe. Seed is hard and brown when ripe.

Seed is air dried in paper sacks for several weeks prior to processing. Seed is removed from stem using a hammer mill with a 0.6 cm (0.25 in) screen. Seed is cleaned using an airscreen cleaner with a 1.55 mm screen and light air. Purities of over 95% are typical. There are approximately 1.2 million seeds/lb. Viability depends on seed fill. A kerosene heater "pop test" is used for quick estimates of seed fill (Tilley et al 2010). Lots with poor viability are re-cleaned with increased air.

Seed is stored in cool-dry conditions with temperatures of approximately 10ø C (50ø F) and relative humidity of 20 to 30%. Seed is not stratified prior to planting.


Soil is a 1:1:1 mix of coconut fiber, compost and perlite. No fertilizer is added to the soil mix. Fiveto 25 seeds are placed on the soil surface and pressed for good seed-to-soil contact. Seed is not covered with any soil or sand, but kept moist with an overhead mist irrigation schedule of 2 minutes/hr from 9:00 am to 5:00 pm for the first 30 days. Day time greenhouse temperatures range from 32 to 43ø C (90 to 110ø F). Night time temperatures average around 30ø C (85ø F). Grow lights are kept on during nighttime hours.

First emergence occurs around 3 to 5 days after planting under temperatures and moisture conditions specified. Full stands (90-100%) are reached in 12 days.

After full establishment, plants are fertilized once per week with Miracle Grow All Purpose Plant Food (15-30-15). After 30 days the irrigation amount is increased to 3 minutes/hr from 9:00 am to 5:00 pm and grow lights are turned off. Greenhouse day time temperatures are reduced to 30 to 32øC (85 to 90ø F).

Three months.

Heat is turned off and temperatures reduced to ambient conditions. Watering is discontinued approximately 3 days prior to delivery.
