lamb's ears with pretty purple flowers???

I believe you have Rose Campion (Lychnis coronaria), whose leaves are similar to (but not as soft as) lambb's ears.

It's a great plant - keep deadheading and it will keep flowering. If you want seedlings, leave some heads on and it should oblige. There's a white version and a deep maroon (sterile) beauty called L.coronaria 'Gardeners' World' which is my favourite.

This is Lychnis coronaria (dusty miller or rose campion)

Lamb's ears - Stachys byzantina - is woolier but also has pink/purple flowers

Thank you everyone, great help, I will definitely follow your advise on seeds, would love more of those in the garden...

This plant seems to have been a feature of GoY this year and has 'grown on me'. The outcome it that I intend to make it a feature in our gardens next year, the seeds have gone on my shopping list.

Try to track down the L.coronaria 'Gardeners' World ' - it will have to be a plant as it's sterile - but it's double and deep maroon and just gorgeous! Flowers for ages.

Will do ...... with a bit of luck and a following wind it may not have to wait until next year then ! :-D

It's called lamb's ear in the United States. There is another variety with the same foliage and white flowers.

We have a plant called 'Lamb's Ears' - but it's Stachys.

That is Lychnis coronaria, Mullein pink, not lamb's ears. But lamb's ears does have pink flowers.
