Good to know about Globe Amaranth
Curated from university extensions, botanic gardens and other primary sources, with the source named on every note.
Worth knowing
What looks like the flower is a cluster of stiff, papery bracts, not petals. That is why the color holds for months when dried, a classic everlasting. per NC State
Size varies by cultivar
Dwarf bedding types stay about 0.15 to 0.2 m for edging; the species and tall cutting types reach 0.3 to 0.6 m. Check the variety before you buy. per Illinois and Clemson
Thrives in heat and drought
A standout for tough spots: it holds color through extreme heat, humidity, and drought when many annuals stall in the hottest months. per Clemson
Deer and rabbit resistant
Deer and rabbits seldom bother it, so it is a good pick where browsing pressure is high. Resistant is not the same as proof. per Wisconsin
Long, steady pollinator draw
The nonstop June-to-frost bloom draws butterflies and bees, a steady whole-season nectar source rather than a brief peak. per NC State
Non-toxic and even edible
Regarded as non-toxic: it is not on the ASPCA toxic-plant list, and the flowers are documented as an edible tea and a natural food colorant. per ASPCA and PubMed Central
