What was checked
Mature height and spread, hardiness zones, sun and the trait tags were checked against named botanical sources for this plant. The bloom months and water need on this page were not, and each fact above says which. The planting, spacing and size sections are derived from these checked facts by a fixed rule, not checked separately, and the plant type is the library's own classification.
When to plant Globe Amaranth
Wait until all danger of frost has passed, then plant out Globe Amaranth into warm soil; in most zones that means late spring. Planted then, it flowers from June to October.
Month-by-month timing for your zone is on the planting calendar; if you garden near zone 9, the middle of this plant's hardy range, start with zone 9 in February. Derived from the plant's category, zones and bloom months plus typical zone frost dates, not checked separately.

How far apart to plant Globe Amaranth
Derived from the mature spread above by a fixed rule, not checked separately: spacing is the spread, center to center.
Space Globe Amaranth about 12 in apart, center to center, so each plant has room to reach its full width.
Add Globe Amaranth to a garden plan and the planner draws it at its full width, so you see the spacing before you buy.
Where these facts come from
Globe Amaranth's height, spread, hardiness zones, sun and trait tags were checked against 8 published sources on July 30, 2026. Each one is linked below with every fact it carried, which can include a fact this page still marks as not yet checked, because a source carrying a value is not the same as the value being held to the standard. Facts not in that list, and the planting, spacing and size sections, are not covered by these sources.

Good to know about Globe Amaranth
Curated from university extensions, botanic gardens and other primary sources, with the source named on every note. A note reports what its source says; where that differs from a fact above, the fact above is this entry's stored value, and its mark says whether it has been checked.
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
What pairs well with Globe Amaranth
Good companions share its growing conditions and add something it lacks: an earlier or later bloom, a lower carpet in front, or structure through winter.
Rock Cress
Shares full sun and low water; blooms in mid spring, before this one opens; evergreen, so the bed keeps its shape through winter; lower at 4 in, for the front of the border.
Sea Thrift
Shares full sun and low water; opens in mid spring and overlaps into this one's season; evergreen, so the bed keeps its shape through winter; lower at 8 in, for the front of the border.
Rosemary
Shares full sun and low water; blooms in early spring, before this one opens; both offer pollinator forage, in different months; evergreen, so the bed keeps its shape through winter.
False Indigo
Shares full sun and low water; opens in late spring and overlaps into this one's season; its seed heads stand through winter, for structure and the birds; both offer pollinator forage.
Flowering Crabapple
Shares full sun and low to moderate water; blooms in mid spring, before this one opens; both offer pollinator forage, in different months; echoes the pink.
Viburnum
Shares full sun and low to moderate water; blooms in mid spring, before this one opens; taller at 6.5 ft, for the layer behind it; both offer pollinator forage, in different months.
Lavender
Shares full sun and low water; evergreen, so the bed keeps its shape through winter; both offer pollinator forage.
Little Bluestem
Shares full sun and low water; its seed heads stand through winter, for structure and the birds; taller at 3.5 ft, for the layer behind it.
