Growth Stages

1

Seedling

2-3 weeks

Tiny plants with first pair of true leaves emerging; seedlings are delicate and burgundy-tinged. Height 1-3 inches.

Keep soil moist but not waterlogged. Thin seedlings to 12 inches apart when 2-3 inches tall. Protect from slugs and excessive wind.

2

Vegetative/Leaf Growth

3-4 weeks

Rapid stem and leaf expansion; burgundy coloration intensifies. Plant reaches 1-2 feet tall with multiple branches. Leaves are large, deeply colored, and edible.

Water regularly and provide light fertilizer every 3-4 weeks. Pinch off top tips to encourage bushier growth if desired. Monitor for pests.

3

Flowering/Inflorescence Development

2-3 weeks

Terminal panicle emerges at top of plant; dramatic drooping flower spikes develop in deep burgundy-red. Plant reaches mature height of 3-5 feet.

Continue watering and fertilizing. Allow flower heads to fully develop. No deadheading needed if harvesting for grain.

4

Grain Maturation

3-4 weeks

Flowers fade; inflorescence hardens and seeds develop within bracts. Seed heads become heavier and droop further. Plant begins to brown and dry.

Reduce watering slightly. Monitor for birds and rodents interested in seeds. Ensure adequate air circulation.

5

Harvest/Senescence

1-2 weeks

Seeds are plump, hard, and easily shaken from bracts. Foliage begins to yellow and dry. Seeds rattle when head is shaken.

Harvest when seed heads dry to brown; do not wait for complete plant death as seeds may shatter. Cut entire heads and hang to finish drying indoors.

Harvest Tips

For leaves: Harvest from 30-50 days, pinching off tender top leaves and stems when plant is 6-12 inches tall; continue harvesting as plant grows. For grain: Wait until seed heads are completely dry and brown (typically 90-100 days), then cut entire panicles and hang upside down in a dry, protected area for 1-2 weeks. Shake heads over a cloth to collect seeds. Remove chaff by winnowing in slight breeze or using a fine strainer. Store dry seeds in airtight container.

Fun Facts

  • 🌱 Amaranth was a staple crop of the Aztecs and was called 'the grain of the gods'; it was nearly lost after Spanish conquest but is experiencing a global revival as a superfood.
  • 🌱 Unlike most grains, amaranth seeds are rich in the amino acid lysine, making them a complete protein when combined with other grains—a quality that made them nutritionally important in ancient civilizations.
  • 🌱 The genus name Amaranthus comes from Greek, meaning 'unfading flower,' referring to the long-lasting dried flower heads that retain their color and structure for months or even years.
