Gomphrena plants are half hardy annuals that reach between 25 and 45 cm in height.
Gomphrena species bloom from summer through to early autumn and carry globe shaped flowers of violet, red or white.
An example of a commonly grown garden member of this genus is the Globe Amaranth.

If growing globe amaranth from seed outdoors then sow the seeds following the last frost of spring; lightly cover the globe amaranth seeds once sown. Ideally amaranths should be spaced at about 20 to 30 cm apart and grown in a sunny part of the garden, For best result grow Gomphrena species in a soil of pH 6 to 7.
If starting off Globe amaranth indoors then first soak the seeds for a day, then sow into pots. Germinate Gomphrena seeds at a temperature of 21 to 25 degrees centigrade in the dark. Transplant the globe amaranth seedlings into the garden following the last frost.
