Verbena bonariensis

Plant details

Tall, narrow, sparsely-leafed stems bear flattened heads of bright lavender-purple flowers that provide useful height in a herbaceous border. This is a short-lived perennial, and because it is borderline hardy, plants may be damaged by winter frosts. This may be avoided by leaving the dead stalks until spring, when new growth is evident, before cutting them back. A protective mulch should be added around them in the autumn with leaf mould or compost. They do, however, self-seed liberally and resulting seedlings are stronger and more drought-tolerant than those that are transplanted. This is a superb butterfly plant, rivalling even buddleja. The Royal Horticultural Society have given it the Award of Garden Merit.

Easy to grow from seed and simply stunning - especially mixed with grasses such as Stipa tenuissima. The bees and butterflies love it and I'm looking forward to seeing where new plants will spring up in the spring from self-set seed. I love it!


I love this plant and once you have it it will seed freely. I like to plant it in the middle of a border as you can see through it and it looks stunning (well I think so) planted with orange varities of Crocosmia. As MrsP says it is also a fav of the butterflies and bees. I love it too!!


I planted this in two places and it didn't thrive. I don't think either spot had enough sun, and one was damp. Disappointed!

I planted this in clay soil in full sun and it grew beautifully.Grown towards the back of a border it provides height,and is so light and airy you are able to see through it to other plants.Bees and butterflies just love it.


its a plant id like but with it being a tender perennial i didnt bother with it but reading mrsPs review and that it self seeds i will grow it for next year thanks


Without a doubt my favourite plant. Although it's a tender perennial and has taken some time to establish - the first year I thought I'd lost it - once it begins to seed itself it seems to go from strength to strength. This year it's popping up in gaps all over my front border. Being so tall it doesn't crowd anything else out. It looks fab against Sambucus nigra Black Lace, and Cotinus Coggygria. I have the form Grace, but it would also work with Royal Purple. It gets lots of sun and is in moist, but well drained soil. A must if you plant for pollinating insects


A very graceful plant and a great pollinator for insects.


Absolutely swear by it each year


Beautiful in the evening it seems to glow. Last year it was 6ft high and 4 ft wide.
This year bought some plugs from ebay and they are growing tall on single stems, so snipped off the top 3in to make them bushier plants, and pushed the trimmings into the edge of the pot and now have many more new young plants in only 2-3 weeks!

I love this plant ,it took a long time to get established in my garden,but now it self-seeds with
ease.Last year one evening at dusk I was watering & dead heading in my garden rapidly losing the light when one magical moment!! A moth fluttered down inches away & landed on the verbena bonariensis flowers,his/her proboscis was so clear to see drinking the nectar from these tiny flowers! Such a magical moment--It is SO important we grow these & other flowers with lots of nectar & pollen to help our little creatures in this wonderful world of ours.


Amazing plant - grew from a 30cm potted specimen to over 6ft in one season!
Great for filling in at the back of a border or raised bed, to give instant height - also nice that the flowers float on top of tall stems, letting lots of light through to the back.
I have mine in a mixed, raised bed, near a purple acer palmatum, with a white shrub rose growing alongside it and some pale pink anemones growing through the actual verbena - looks beautiful, if I do say so myself :-)

Just bought another one thank you. Will put it the sunnier border side and not the damp as I had hoped. All my plants are for the bees and butterflies. I have one thin, long bed full of meadow sweet, fennel and asters parallel to a lavender hedge. I have to be careful when I walk by as a cloud of bees rise up from the plants. I will not cut them back until spring, so insects can winter in the stems and birds can have any seeds.




Stunning plant hope it flowers this year it grew to nearly 6foot last year, but isnt overpowering as i have a small garden. I also had butterflys flapping around all summer, cant wait to see them again!


I just love this plant.Insects and butterfly adore this. Took stem cuttings and they all took.


It is in among our climbing roses - about 8' tall - TOTALLY sensational plant!


One of the most beautiful and useful plants. A gardeners dream.
