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 1.6 ft wide at maturity, in roughly 1 year.

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: for the middle of its range, start with zone 9 in February.

Comes in 11 varieties across 5 colors

Good to know about Verbena

Curated from university extensions, botanic gardens and other primary sources, with the source named on every note.

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.

    Feather Reed Grass

    Shares full sun and moderate water; taller at 4.9 ft, for the layer behind it; its seed heads stand through winter, for structure and the birds; orange against purple, for contrast.
