Planting: Sow 1/2 inch deep 12-24 inches apart.
Care: Generally easy to grow and tolerant of most garden soils.They do well with heat and drought once established, but may need stakes to help support them as they grow tall.
Harvesting: Harvest seeds when they have a pronounced grey stripe. The petals will be all dried up and the back of the flower heads should turn yellow. Cut the heads from the stalks and hang upside down in a warm, dry place. Once completely dried, the seeds should come out of the head easily with a little rubbing. Let them continue to dry out until the shells are brittle. Eat raw, or roast in your oven with a little salt.
Germination: 10-14 days
Days to Maturity: 80-100
Preferences: Plenty of water, full sun, well-draining soil
Special Instructions/Tips: These plants make a great wind break because of their height but, be careful not to plant them in a way that will put unwanted shade on your garden.
