Plant of the Week
Homestead Purple Verbena
Latin: Verbena canadensis 'Homestead'
 Perennials have captured the hearts of gardeners throughout the nation.
Hundreds of new plants have appeared in our gardens in the last decade,
including Homestead Purple verbena. It’s such an outstanding plant that it was
selected as an Arkansas Select plant for 2001.
Since its introduction in the early 1990s, Homestead Purple has sparked
widespread interest in all things verbena and has spurred the introduction of
over 40 new hardy types.
This rampant perennial grows to 3-feet wide and a foot tall and is topped
with a mass of bright purple blooms that start in the spring and continue until
frost. Its leaves are deep green, scalloped, coarse-textured and up to 4 inches
long.
The plant’s stem trails across the ground and turns up at the tips. Flowers
are borne in finger-like spikes that are held above the foliage. The flowers
grow to 3 inches long and are crowded with individual five-petaled,
trumpet-shaped florets.
Homestead Purple is listed as a cultivar of Verbena canadensis, which
grows wild throughout the southeast, including all of Arkansas, and ranges as
far north as Zone 5 in Iowa. The species is a perennial, but a temperamental one
that is very particular about its exposure and drainage, especially during the
winter.
In all probability, Homestead Purple is a chance hybrid with another verbena
species because its identifying characteristics and vigor are not characteristic
of the straight species.
The discovery of the plant is due to the keen eyes of two University of
Georgia horticulture professors, Alan Armitage and Mike Dirr. Armitage is one of
the nation’s foremost authorities on perennial plants, while Dirr is the
undisputed woody plant guru.
The two were returning to Athens, Ga., when they drove past a purple mass of
flowers neither recognized. They did a U-turn and asked the lady who lived on
the homestead about the plant. She didn’t know much about it – apparently it had
been growing there for years. They collected cuttings and the plant went on to
fame and glory.
Since 1998, the University of Arkansas and the greenhouse and nursery
industry, now combined into the Arkansas Green Industries Association, have met
and selected plants to designate as Arkansas Select plants. The criteria for
selection are that the plant be relatively new, that it be adapted throughout
the state, and that it be easy to grow. Homestead Purple meets these criteria
admirably.
Purple is a color that may scare some gardeners, but the vivid rich purple of
Homestead Purple combines well with most other colors. It’s an especially good
foil for pastel-colored flowers when it’s used at the front of the border or in
a rock garden.
Homestead Purple should be placed in full sun in a well drained soil. Like
most fast growing perennials, it responds well to good soil preparation and
occasional fertilization.
This past winter, gardeners in the northern part of the state did lose the
plant, probably as much due to wet soil during the winter as the cold. But it
should overwinter successfully nine out of 10 Arkansas winters.
Homestead Purple is such a rampant grower that it will quickly fill in any
open space. Occasionally it will have a small amount of insect damage on its
leaves, but its impressive growth rate and abundant flower production quickly
hides any signs of injury.
