Gomphrena plants need full sun to partial shade they are not fussy about soil type and will even grow in very poor soils. They can glow in beds, borders, containers, pots, etc. Even though they are very drought tolerant plants, they do best with regular watering and fertilizer application. Do not use a high nitrogen fertilizer as this will just lead to excessive foliage.
Plant Gomphrena seeds either indoors, several weeks before the last frost is expected, or directly outdoors when the temperatures have warmed. If sowing Gomphrena seeds indoors, transplant the seedlings to the sunny garden spot when they are several inches tall.
Many gardeners recommend soaking Globe Amaranth seeds 24 - 48 hours before sowing as the water helps to prime the seed for germination. If growing Globe Amaranth from flower seeds specifically for cutting, space the plants closer together to force the growth of longer stems.
