Plants of Amaranthus caudatus, A. cruentus and A. hypochondriacus may cross-pollinate with each other and with weedy amaranth plants; Amaranthus tricolour will not cross-pollinate with other species. Pollen is very fine and isolation cages and paper bagging are not effective methods of isolating plants.

What is Seed Saving?

Seed saving is the practice of collecting and storing mature seeds from open-pollinated plants. By allowing plants to reach full maturity and harvesting the seeds, they can be cleaned, dried, and stored for future use.
