Hello, a friend brought this seed head back from the golf course  and wondered what it was...... I just KNOW I should know this, but cannot think... it has quite a stiff stem , rough to touch... mare's tail type thing?? Whole piece shown is around 15 cms.......my friend thought it had had pink flowers.... but this doesn't ring any bells with me

Looks like Hesperis matrionalis---Dame's Rocket.

Another option would be:  Cardamine  pratensis
(either way, it's a Crucifer)

"Dame's Rocket" ? I would say "sweet" rocket...but  yes, I think you are correct.... I think of that as having white flowers but of course there are pink ones, too. Thanks, Carlo!

I think the whole plant was too tall to be a Cardamine, even allowing for extension in fruit, also the seed pods are very long.

White, pink and purple here....

I've not heard Dame's Rocket before - I know it as Dame's Violet because of the sweet scent. That could be the seed head - I''ll look in the morning if it is still there.

It's called "Dame's Rocket" here in Newfoundland,
.

Exactly!! The argument for the use of botanical names, in a nutshell!

Another possibility is it could be rape - another cabbage after all - particularly if it's near to farm land.

Sue, chum said flowers were pink... isn't rape always yellow?

OOps - missed the bit about pink -
