Amaranthus Tricolor is best grown outside but can be grown indoors and beginning their sowing 4-6 weeks before the last frost. When replanting the seeds outside, make sure there will be no more frost, these flowers do not survive in cold weather. When growing outside, make sure the soil is warm and that will allow the germination to arise quickly. The flower should be placed in full sun for the best lively colors. Well-drained soil is fine and this variety of Amaranthus is quite drought-tolerant. Do not use rich soil because this will cause the leaves to lose their vibrant color. As the plants continue to grow, they usually need some staking to hold them upright.
