Amaranthus Germination Information

Amaranthus is the botanical name for Summer Poinsettia and Joseph's Coat
Amaranthus Seed Germination How to Sow Amaranthus:
  • For best results, sow indoors 3 to 4 weeks before planting outdoors
  • Leave the seeds uncovered, and maintain a temperature of 70-75° F
  • sow outdoors after danger of frost has past, leaving seed uncovered
  • Indoors or outdoors, germination takes 10-15 days
  • When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

How to Grow Amaranthus:
Spacing:  Space seedlings 12-24 inches apart in full sun

Temperature: Indoors, grow on at 65° F nights and 80-85° F days, in full light

Soil: Amaranthus grows in any soil, but prefers one that is rich and well-drained. Water sparingly –– once established, the plants will not tolerate wet soil

Appearance and Use:

Brightly colored plants, 2-6 feet tall and 1-2 feet wide, may require staking. Tiny, insignificant flowers may be erect or drooping in tassel-like spikes of red or purple, blooming from midsummer till frost.
