Buy Verbena bonariensis verbena: Sought after for its graceful habit

This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

  • Position: full sun
  • Soil: moderately fertile, moist, well-drained soil
  • Rate of growth: average to fast-growing
  • Flowering period: June to September
  • Hardiness: borderline hardy (may need winter protection)

    Tightly packed clusters of lilac-purple flowers top the tall branching stems from June to September. This stylish perennial has been enjoying a resurgence of interest in recent years. It is perfect for a sheltered, sunny spot with well-drained soil and its open, transparent shape means that it can easily be used at the front, middle or back of the border.

  • Garden care: In cold conditions Verbena bonariensis can suffer dieback if cut back in autumn, so it's best to leave the plant until spring and cut back the old growth when you see the new shoots emerging at the base. Also it's a good idea to mulch around the base of the plant with a deep, dry mulch in winter to help protect the plant. Where the plant is grown in partial shade the stems may need to be supported - if this is necessary use natural materials such as brushwood or twiggy pea-sticks.

Notes on Verbena bonariensis

"Rigid tall stems of indestructible, everlasting purple flowers to peek through on this must-have butterfly plant that needs massing together at the front of a border - like a curtain - supports dahlias as effectively as bamboo canes"

Not sure what happened


I planted this in one of my borders and it grew to massive height so we really enjoyed it, but unfortunately there was not sign of it this year so not entirely sure what happened, it went from being rudely healthy to totally disappearing.

Great for bees


A great addition to my front garden, planted amongst a mix of shrubs and bulbs and bushes, tall with a pleasing purple flower and very bee-friendly




i would buy again






good value


Healthy, vigorous plants that reached full height in first season. Delightfully ethereal in appearance, best not to plant in windy exposed area unless supported by more robust bedfellows.




Must for the garden


Plant this for the first time WHY haven't i planted it before i planted it with some cow parsley in a bed out side patio doors was lovely watching the butterflies and the whole movement of it .definitely a must for any garden.




I would definitely buy this plant again


These plants give height, structure and interest to my small garden and are one of my favourite plants


South London


Super plants


Easy to place at back of patio plants




I would buy from crocus again


Good height and colour for back of borders.




lovely graceful plant


lovely height in the garden that does not block plants behind

Impressive - eventually


They took longer then expected to grow to their expected height. Too late for the wedding when I needed a smart looking garden. Eventually, they formed an impressive backdrop. As it's now winter, they are I hope dormant and will return in the spring? Or summer? More info would be appreciated.

Verbena bonariensis

4.7 112


I have just ordered some Verbena bonariensis from you. Sept 11th. Should I plant them now or over winter in the greenhouse please


These plants are not quite fully hardy, so it really depends on where you live and how cold it gets. It will be safer to overwinter them in a cool greenhouse, but having said that, mine have been snowed on and they have been unaffected - but I do have very freely draining soil. That is crucial as it is usually the combination of cold and wet that will kill off a less-hardy plant in winter.


Hello, I am a newbie gardener, and was hoping to grow some Verbena bonariensis, in a corner of the garden (south facing) - both too help both attract butterflies, but also to act as a 'filler' in front of an unsightly scrubbery (not mine). The area I have to plant them is about 3ft * 2ft. How many plants would I need to plant so they would grow into a 'dense'-ish group ? Many thanks for any help ....


Hello, I have never seen these plants look dense, but you could plant them at 30cm intervals if you want a cluster.


I bought these last year and had a fabulous display all summer. They got unruly so I cut them down, I now realise that was a mistake because they haven't come back this spring. I would love to plant them again but am worried that they are borderline hardy. I live in a rural part of Nottinghamshire and it can get cold and windy. If I did buy these again if I left them alone - didn't cut them back - do you think they could survive a cold winter? How would I protect them against a harsh frost/snow given their height?


Hello, These are only borderline hardy, but they tend to survive the cold better if the soil is very freely draining, as the combination of cold and wet tends to be the killer. Keeping the top growth intact will also help however as it does provide the crown with a little extra protection. Alternatively, you could apply a generous layer of dry mulch around the crown of the plant in autumn.


Will this plant grow well in a pot?


Hello, I have seen this growing happily in a large pot, however I suspect it would be even happier if planted in the ground.


If I buy these plants now will they be OK in the pots outside until spring and do they go well with lavender plants?


Hello there These plants combine well with lavenders but they are classed as borderline hardy so will need protection through the winter. Ideally I would keep them in a frost free greenhouse, or else you could keep them outside in a sheltered spot where they won't catch a frost or get waterlogged, and protect them with frost fleece. Hope this helps

Hello! I have a question about your phrase ' Plant it among the warm-red Dahlia 'Bishop of Llandaff' and it will act as supports, negating the need for staking, whilst providing a dazzling display.' Can you confirm which plant will be supporting which? And if I want to do this how close should I plant them together? Should I alternate one plant for the other or should I plant a row of one in front of a row of the other? Thanks for your help!


Hello, The verbena has quite rigidly upright stems, which can help prop up other plants around it - like for example a tall dahlia. As for how to plant them, that depends on the effect you are trying to achieve, so you can create rows or randomly intermingle them, at around 30 - 45cm intervals.


Hi, I know virtually nothing about gardening, but am wanting to learn. I love this plant, can I buy a couple now and plant them in a very sunny spot? Will they be ok and how can I look after them best? Thanks Louise


Hello there This plant is a borderline hardy perennial. It loves a sheltered sunny spot, with well-drained soil and will die back in the autumn. If you have a really protected warm garden then you might be able to plant it now and it will come back in the spring, otherwise you can overwinter in a greenhouse, or plant out next spring after the last frosts. Hope this helps.

when can I plant these?


Hello, The best time for planting is spring, but they can also be planted in summer providing you make sure they are kept well watered during the warmer weather. If you have a very sheltered garden (they are not fully hardy) with soil that drains freely in winter, then they can also be planted in autumn.


If I buy the 9cm pots, how should I then care for them? Should they be kept indoors until frosts have ended? Will they suffer if kept in a warm house?


Hello there I would keep them outside in the garden, in a sheltered area where they won't be caught by a frost, or in a frost free greenhouse until you can plant them into the garden. You can also protect the plants with a frost fleece. I have attached a link below to the fleece. Hope this helps.

Hi, I bought Verbena bonariensis from Crocus in March 2012, they grew brilliantly through last season. However, it is now 12 May 2013 and they show absolutely no sign of any new growth from the base. Does this mean they haven't survived the winter? Or, should I give them a bit longer to see if they start growing before I remove them? I haven't cut back last year's growth yet as per instructions. Your help is most appreciated, thank you.


Morning I'm afraid they may have been caught this last winter. They are borderline hardy, so do need protection during the winter in colder areas. However many plants are late emerging this year as it was a long cold winter, so I would give them another couple of weeks to see if any new growth starts to come through, if not, then sounds like they have died.



Indulge a passion for ornamental grasses by creating a prairie- or meadow-style garden. They can be richly planted with native wildflowers or a selection of complementary perennials and self-seeding annuals to create a naturalistic planting effect.

These lovely plants produce a succession of lily-like flowers each of which lasts for just one day. At first, this seems rather disappointing, but they are such bright, exotic flowers and produced in such profusion that this isn't actually a drawback. In

Plants with seedheads for the winter garden

Some plants have intricate seed heads which provide a profile and refuge to insects in a winter garden, and seed heads can be beguiling. However care must be taken not to allow seed heads that deliver hundreds of seed a free reign.
