Convolvulus Tricolor 'Blue Ensign'

I took this picture in my friend's garden last summer. He told me what it was called but I've forgotten. Can anyone help please?

I could be wrong as I'm a novice but looks like cosmos

@pauld Yes, it's cosmos!

Help me identify this plant

Hello Paul 👋 Thank you for posting what we hope will be the first of many photos. 👏

You can find other like-minded gardeners by tapping on Discover and then "Popular" or "Recommended". There you will see other great photos of plants and gardens and you can of course “follow” anyone that you see there should you like to do so!

Should you ever need to reply to a message in your feed or just want to say 'hello', simply @username an individual i.e. @teamgardentags and that person will get an alert in their profile. Really hope this is helpful and you enjoy using GT! 😃

Thanks also for asking us to help identify your plant #PlantID. Fellow GT'ers are you able to help Paul? @PlantDoctor @David @barbaramatthews @justin @richard.spicer.7906 @thedanielrichards @Garyg @linfoster @joanboston @gardening_greek @tiggrx @kathy
