What Is It?

Chia is a flowering member of the mint family grown primarily for its edible seeds. Native to Mexico and Central America, it produces attractive spikes of blue, purple, or white flowers that attract bees and other pollinators.

Historical Uses

Chia was a staple crop of the Aztec and Maya civilizations. The seeds were consumed whole, ground into flour, added to beverages, and used as a valuable trade commodity. Warriors often carried chia as a portable source of energy during long journeys.

Where Should It Be Grown?

✓ Raised Beds

✓ Directly in Garden Soil

✓ Large Containers (minimum 5 gallons)

✓ Community Gardens

Chia grows best in locations with full sun and good drainage.

Wildlife Protection: Generally not required. Deer and rabbits rarely bother mature plants, though young seedlings may occasionally be nibbled and can benefit from temporary protection.

How to Grow

Direct sow after the last spring frost, or start indoors 4-6 weeks before transplanting. Lightly press seeds onto the soil surface and cover with a very thin layer of soil. Keep evenly moist until germination occurs.

Harvesting

Allow flower heads to mature and dry on the plant. Once the seed heads turn brown and papery, cut the stalks and hang them upside down in a dry location.

Gently rub the dried seed heads between your hands or inside a paper bag to release the seeds.

Seed Collection & Storage

Collection Method: Harvest only fully dry flower heads. Remove plant debris and separate seeds from chaff using a fine sieve or by gently winnowing.

Storage Method: Store seeds in a non-bleached paper envelope, amber glass jar, or airtight container in a cool, dark, dry location.

Seed Viability: Approximately 4-5 years when properly stored.
