Bees and butterflies love Verbena bonariensis, and so do I! It’s also known as ‘purple top’, 'South American vervain', 'tall verbena' or ‘Argentinian vervain’.
I actually find it to be very versatile in a garden, including small ones like mine (as I will explain) and it provides food for bees and butterflies from summer through to the autumn.
Bees and butterflies don’t mind sharing the dainty, tubular, nectar-filled clumps of flower heads, and it’s not unusual to see many butterflies and bees on a flower cluster at once.
Apart from attracting bees and butterflies, another great thing about Verbena bonariensis is that it’s easy to grow, and relatively free of diseases.
I first experimented with Verbena bonariensis several years ago. I sowed seeds into pots and kept them under cover in a temporary polythene ‘greenhouse’.
Back then, we didn’t have a greenhouse made from glass, but my method worked a treat, and I soon had young plants to transfer to the front garden.
Our garden is small, but the few tall, very slender stems don’t look out of place.
In fact, the Verbena adds an appealing ‘softness’ to the border.
The flowers attract bumble bees, honey bees, and a variety of butterflies: peacock, small tortoiseshell, comma, white, and red admiral.
If you’d like to attract bees and butterflies to your garden, you can follow my method, by simply sowing a few seeds in compost in the autumn. Place them in a greenhouse or propagator. Plant them out the following year into a sunny position.
Verbena bonariensis can look straggly. The stems can be cut back in the early spring.
An especially harsh snowfall can also damage plants (as I found out - that same year, a fabulous lavender was also ruined), so you may need to cultivate new plants - unless they self-seed. Fortunately, this was my experience, so I had a few new plant to compensate for the ones I lost.
Here are more images of beautiful butterflies feeding on purple top in my garden - you may attract some, all or even more species:
bonariensis looks wonderful in a flower border, especially among other cottage
garden flowers. You can grow it toward
the back, or plant it in a large swathe at the front of the border.
Verbena bonariensis would also look great in a wild, informal garden, and yet it could also make a design statement if incorporated within a more structured, formal layout.
I saw a wonderful border full of grasses that had been designed with butterflies in mind. Verbena bonariensis had been added, and of course, bees were attracted too. The splashes of purple were welcome among the greens and browns, and didn’t look out of place.
If you have a wall or wish to add softness or feeling of ‘airiness’ to the flower border, again, this is a great plant to consider. It can also provide beautiful contrast against bulky or heavy structures.
Add in the butterflies and bees, and you’re sure to have an attractive display in your garden!
