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).

Verification
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?

See Verbena in a garden plan: the planner shows it in 3D beside everything else you add, growing toward this size over the years.

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.

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.

How the checking works, and what each standard covers, is on the verified plants page.

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

Non-toxic, but check the name

Garden verbena is not on ASPCA's toxic list. But lemon verbena, a same-family cousin, is listed toxic to dogs, cats and horses, so confirm the botanical name. per ASPCA

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.
