The Amaranth Family has a formal name which is Amaranthaceae. Let chat about some of the members:
Veggies:Â Â Swiss chard, beets, spinach, purslane
Grain:Â Quinoa
Herbs:Â Epazote
Flowers & Blooms:Â Amaranth, Globe Amaranth, Cockscomb/Celosia, Portulaca
Similarities:  Purslane and portulaca are both succulents. The leaves for all the veggies listed above can be eaten. While I put Amaranth in the flower category, it produces a grain like quinoa.
Differences:Â Â As for the veggies, beets are primarily root veggies and the rest are greens.
The last plant family that we reviewed was the Grass Plant Family.
