Verbena
Verbena
Verbena blooms from May through October.
Months here are Northern Hemisphere months; in the Southern Hemisphere, shift them by six months.
Growing Verbena
Plant it in full sun. It prefers moderate water. It is hardy in USDA zones 9–11. Expect it to reach about 10 in tall and 20 in wide at maturity, in roughly 1 year (not yet checked).
Pets
- Not yet checked for pets.
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 Verbena. That is not a clearance: check its safety for people and pets before planting.
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 Verbena
Wait until all danger of frost has passed, then plant out Verbena into warm soil; in most zones that means late spring. Planted then, it flowers from May 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 big does Verbena get?

How far apart to plant Verbena
Derived from the mature spread above by a fixed rule, not checked separately: spacing is the spread, center to center.
Space Verbena about 20 in apart, center to center, so each plant has room to reach its full width.
Add Verbena 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
Verbena's height, spread, hardiness zones, sun and trait tags were checked against 12 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 Verbena
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
Its worst disease, powdery mildew, hates the very spot the plant loves: full sun with generous spacing for air flow gives the most bloom and the least mildew at once. per Clemson and NC State
Heat tolerance depends on type
In hot, humid regions, seed-grown bedding verbenas often stall once summer heat rises, while vegetatively propagated types keep going. Pick a vegetative series, not a seed mix. per Clemson
Shear it to rebloom
When bloom stalls in mid-summer, cut the whole plant back by about one quarter, then water and lightly feed. It returns to bloom in 2 to 3 weeks. per Clemson
Deer rarely browse it
Two extension services report deer usually leave garden verbena alone, though it is deer-resistant, not deer-proof, and hungry deer under pressure may still sample it. per NC State and UGA
Feeds butterflies and hummingbirds
Its long summer-to-frost bloom is a steady nectar source for butterflies, bumblebees, and hummingbirds, though as a non-native it is a moderate rather than top-tier pollinator plant. per Clemson
What pairs well with Verbena
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.
Chinese Fringe Flower
Takes full sun to part sun and moderate water; blooms in early spring, before this one opens; stands well above at 8 ft, a canopy to plant beneath; both offer pollinator forage, in different months.
Castle Rouge Blue Holly
Shares full sun and moderate water; opens in mid spring and overlaps into this one's season; stands well above at 6.5 ft, a canopy to plant beneath; evergreen, so the bed keeps its shape through winter.
Indian Hawthorn
Shares full sun and moderate water; opens in mid spring and overlaps into this one's season; taller at 5 ft, for the layer behind it; evergreen, so the bed keeps its shape through winter.
Swamp Sunflower
Shares full sun and moderate water; overlaps, then carries the display into late fall; stands well above at 6 ft, a canopy to plant beneath; its seed heads stand through winter, for structure and the birds.
Ironweed
Shares full sun and moderate water; taller at 5 ft, for the layer behind it; its seed heads stand through winter, for structure and the birds; both offer pollinator forage.
Prairie Blazing Star
Shares full sun and moderate water; taller at 3.5 ft, for the layer behind it; its seed heads stand through winter, for structure and the birds; both offer pollinator forage.
Rosemary
Shares full sun and low to moderate water; opens in early spring and overlaps into this one's season; taller at 3.5 ft, for the layer behind it; evergreen, so the bed keeps its shape through winter.
Feather Reed Grass
Shares full sun and moderate water; taller at 5 ft, for the layer behind it; its seed heads stand through winter, for structure and the birds; both offer pollinator forage.
