Out of all the summer-blooming perennials in our garden, one is consistently towards the top of my list of favorites: Verbena bonariensis, commonly know as tall verbena, purpletop verbena or purpletop vervain.
This South American native has lantana-liked flower heads on top of tall stems equipped with sparse narrow leaves.
This produces a fluid, airy effect and makes Verbena bonariensis perfect for mixed borders where it can weave in and out of plants next to it.
I have Verbena bonariensis planted inside and outside the 4-ft. fence that surrounds our front yard. It’s tall enough to peek over the fence without blocking our view.
Outside the fence, some stems have become intertwined with our Leucadendron ‘Safari Sunset’ so it looks like the flowers belong to the leucadendron.
I also love the way Verbena bonariensis contrasts with the inflorescences of our Karley Rose grass (Pennisetum orientale ‘Karley Rose’)
The flowers of Verbena bonariensis are irresistible to bees and butterflies.
Verbena bonariensis is hardy to zone 7. Some sources say it reseeds heavily but that’s not the case in our garden. I put two plants in the ground a number of years ago and I still only have two. I I wish it would reseed just a little bit because I’d love to have babies!
