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 Flowering Tobacco
Wait until all danger of frost has passed, then plant out Flowering Tobacco into warm soil; in most zones that means late spring. Planted then, it flowers from June to September.
Month-by-month timing for your zone is on the planting calendar; if you garden near zone 10, the middle of this plant's hardy range, start with zone 10 in January. Derived from the plant's category, zones and bloom months plus typical zone frost dates, not checked separately.

How far apart to plant Flowering Tobacco
Derived from the mature spread above by a fixed rule, not checked separately: spacing is the spread, center to center.
Space Flowering Tobacco about 12 in apart, center to center, so each plant has room to reach its full width.
Add Flowering Tobacco 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
Flowering Tobacco's height, spread, hardiness zones, sun, water, bloom months and color and trait tags were checked against 14 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 Flowering Tobacco
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.
Safety
Poisonous: every part holds nicotine, a neurotoxin. Toxic to dogs, cats, horses; keep it away from children, pets, and grazing animals. NC State rates the poison severity High. per ASPCA and NC State
Worth knowing
The same hawkmoth is both hero and villain: it pollinates the night-open flowers in flight like a hummingbird, and its caterpillar is the tobacco hornworm that chews the leaves. per Wisconsin and PubMed Central
Fragrance depends on type
Species and heirloom types (N. alata, N. sylvestris) perfume the evening; many compact bedding hybrids were bred for daytime color and give up the night scent. per NC State and Missouri Botanical
Keep from the tomato family
Do not plant it near tomatoes, peppers, potatoes, or eggplant: these nightshade relatives can share and spread tobacco mosaic virus. Watch for aphids and the hand-pickable tobacco hornworm. per NC State
A night pollinator plant
Its long, fragrant, night-open tubes are built for nocturnal hawkmoths that hover and feed in flight like hummingbirds. It is a night specialist, not a daytime bee magnet. per Wisconsin
Self-seeds, but manageable
It self-seeds readily from many tiny seeds, but volunteers are easy to spot and pull. Deadheading the spent flower clusters cuts down on self-sowing. per Wisconsin
Site fragrant types by paths
The evening scent only pays off up close, so plant the fragrant species types beside a patio, doorway, or path you use after dark. Scentless dwarf hybrids can go anywhere. per NC State
What pairs well with Flowering Tobacco
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.
