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"

Great results

I bought several plants for a raised bed. When they grew, they really grew tall and they've been in flower all the way through the summer into mid November. Great for adding interest to bed.

I have never been able to successfully grow this plant, but I have a new garden now (still with heavy clay) so I thought I'd give it another go. I bought the 6 pack offer and although they looked a bit small and shrivelled initially, I planted them in a row and after a slow start, they really romped away. They still look good now and have managed to withstand the fierce cold east winds at the top of a hill in Lancashire. Now the test will be whether they survive our winter and return next year. I followed Monty's instructions for taking cuttings a couple of months ago as an insurance policy so let's see if I'm successful with these. Really impressive plant and you'd never guess there were only six plants when they are at their full height and growth. Another big plus is the amount of bees and butterflies they have supported over the Summer and Autumn.

The best plant I have ever bought, tough as old boots and flowers its socks off for a very long period. It will grow anywhere and self seeds, but easy to remove if in the wrong place.

This stands tall and unsupported at the back of a border. It is often described as "looking as though it floats". This is true. A hardy perennial which looks charming behind a variety of plants. Long lasting too.

There is a comment about Verbena being a natural support for Dahlias, well how true that is. We have had very heavy rain and wind this week and all my Dahlias are safe. They do have metal stakes as well but the Verbena seems to really help. Highly recommended.

Growing nicely with plenty of flower buds

I bought one of these plants for a tall planter, to go with other plants to attract butterflies and bees. It arrived safe and is healthy, and has grown well over the last months or so with plenty of flower buds appearing. Worth noting that it is quite tall (about 1M currently and likely to get taller) so is probably best planted behind shorter plants.

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 ....

newbie-rich

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

Helen

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?

Humbert

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.

Helen

Will this plant grow well in a pot?

NanaJ

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

Helen

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

Hilux

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. http://www.crocus.co.uk/product/_/fleece-cold-protection/classid.200879/ 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!

NewBee

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.

Helen

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

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?

christopher

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.

Helen

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?

Novicegardener

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. http://www.crocus.co.uk/product/_/fleece-cold-protection/classid.200879/ 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.

GardenerLassie1

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.

Powdery mildew on my plants Hi, I wonder if your plant doctor may be able to answer a query for me. I have bought a few Verbenas from yourselves and they all seem to have suffered the dreaded powder mildew problem. I have sprayed with a recommended product and discarded the affected leaves but don't know if I have sorted the problem or not sufficiently? I read that this often affects plants that are under stress, - I did keep all the plants potted up (although some in larger pots than at purchase) close to each other for some time. I wonder if that might be why this happened ? Any advice would be welcome. They are now all in the garden and hopefully will thrive. Sue

Sue Hulkes

Hello Sue, Powdery Mildew is caused by the plants being too dry and having poor air circulation, which are usually made worse when the plants are growing in pots. It sounds as of you have tackled it correctly, so they should improve.
