84 AMARANTHUS CAUDATUS
Propagation
Amaranthus caudatus
var. atropurpureus
Seed: In the greenhouse, lightly cover seed in a peat/perlite medium and place
under mist at 70–75F (21–24C). Germination occurs in 7–10 days. Approximately
0.03 oz (0.9 g) of seed yields 1000 plants (Nau 1999). Most amaranth
seed is direct sown. Seed may be direct sown in the field after potential for frost
has passed. Rates of 0.13 oz per 100' (12 g per 100 m) are common; Ralph
Cramer in Elizabethtown, Pa., uses a higher rate, up to 0.4 oz per 100' (38 g per
100 m). Higher rates yield smaller flower heads, which may be more useful for
certain purposes.
