Gardeners' Notes:


On Jul 12, 2020, BensonGardens from Saint Paul, MN wrote:

So I used to think this plant was pretty but because the flowers were so small i wasn't excited about it. However my opinion has changed. It is quite tall and and has a very airy appearance. I have several plants of Verbena hastata punctuating a bed of tall golden trumpet lilies and the bright purple/blue blossoms really set off the gold lily flowers as they float gracefully over the garden bed. Sometimes less is more. Also these flowers are very popular with pollinators and have a slow sequence of bloom so they flower for quite an extended time.

This is a pretty native perennial that I see growing wild in meadows in se PA and remember in central WI. I see it growing as individual plants rather than in masses.It is sold by native plant nurseries for naturalistic landscapes. I don't know of this fine plant from conventional nurseries.

I have this wild all over my property, but have not been here for a dry year yet so cannot speak for it's performance then, and it has put on an impressive display all season, even in a recently graded area of deep clay-y sand along with false sunflowers and 2 other varieties of yellow flowers I cannot ID...nature designed this planting and it is stunning. I also use it in wildflower bouquets (harvesting very lightly) and it lasts over a week with the parts of the flower that open inside the house a lovely lighter shade of lavender for a lovely two-toned miniature bottle-brush effect.

I have a few plants in my garden - grows very well - in the wild they are very common, along with another species, produces the most purple flowers on roadsides in Eastern United States in mid Summer.

Once DH and I were walking along a trail high above a low-lying wetland that was awash in vivid, dark lavender-purple, and for a moment, it was as if I was inside a picture of a field of lavender in Provence, France in one of my gardening books. Such is the effect of a wide plain filled with blue vervain from a distance - beautiful and awesome. Up close, there must have been a couple dozen kinds of other plants down there with it, but all has now been trounced by the very invasive Polygonum cuspidatum (Japanese knotweed).

Begins to bloom late July in Cos County, NH alongside of damp rural roads.

Blooming in late summer/early fall here in west KY, Blue Vervain graces the roadsides and damp meadows with a long blooming period. The tall spikes have the appearance of a candleabra with tiny blue 'flames.

In ancient times, it was thought to cure all sorts of ailments and was highly regarded as 'big medicine'.

Found pretty much throughout the eastern half of the country, it seems to survive in a great variety of conditions, but prefers damp thickets, shorelines and roadsides.

This verbena grows into a large clump 4-5 feet tall. It has stiff erect stems, lance shapes foliage and a spiky candelabrum of flowers. The flowers may not be as large as the garden varieties of verbena but they are abundant and bloom for a very long time during the summer months. The tiny tubular shaped blossoms grow in whorls up the pencil shaped spikes and are a treat for bees and butterflies.
This is a medicinal species of verbena and has been used for centuries for its mild sedative affects as well as female ailments, stomach cramps, colds, fevers and other diseases. Its genus name is Latin for sacred plant. Early settlers believed it would ward off evil spirits. Its a wonderful native to add to the garden.
This plant loves wet soils and can reach a height of... read more
