Hi wisdomous hive of mumsnet gardeners!

Can anyone please identify this plant for me? We're currently landscaping our new garden and I spotted these at a cottage we visited over the weekend, would love to plant some in ours but not sure what to search for! (and picture of a butterfly as that's my motivation for planting them!)

Thanks in advance 😊

Verbena

Here’s what my plant is app thinks it is. Beautiful!

Thanks both! I told DH that someone here would know straight away rather than us typing in "purple flower" into Google to narrow it down 😂

Verbena Bonariasis , it’s one of my favourite plants!

I think is a verbena bonaviensis

It's Verbeba Boneriensis. One of my favourites, it grows anywhere and flowers for months. Although tall it seldom gets wind damage. Once you have some it seeds everywhere. I have 10000000s of them.

At the risk of sounding like an Amazon algorithm, if you like Verbena you might also like knautia and astrantia
