Pets
- No toxic listing found for dogs and cats in the sources we check.
Lists differ and none is complete. If a pet eats a plant and seems unwell, call a veterinarian or a pet poison helpline.
No toxicity note is on file for Globe Amaranth. That is not a clearance: check its safety for people and pets before planting.
What was checked
Nine facts were checked against named botanical sources, each recorded beside the sources that carried it: mature height and spread, hardiness zones, sun, water, bloom months and color, the trait tags, and years to mature size, which rests on a recorded house rule where no publisher states one and is marked so. Soil, diseases, pests, toxicity and the plant's own names have not yet been read for this plant, and its trait tags are the ones a feature uses rather than every word a page prints. Each fact above carries its own mark. 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, water, bloom color and trait tags were checked against 12 published sources on October 29, 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
Edible flowers
The flowers are documented as an edible tea and a natural food colorant. per 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.
Cleveland Sage
Shares full sun and low water; blooms in mid spring, before this one opens; both offer pollinator forage, in different months; evergreen, so the bed keeps its shape through winter.
