Looks like valerian which seeds easily. A good nectar plant but can be invasive if you let it get a hold especially in cracks in paving, mortar or near drains. Comes in shades of pink-red, pink and white.

I think it's valerian too. It's very pretty but eats mortar. We mistakenly let some grown in the drive wall because it looked so pretty. Big mistake, it cost a fortune to get it out of the wall and rebuild.

I like the Valerian plant and noticed last year for the first time when it flowered I had some in amongst some other plants. I’ll pull it up and plant somewhere else. Have looked in same spot it was growing before but there are too many dandelions.
Thank you both.

We have then in the front garden sprouting from gravel never had them before.

Yep, looks like valerian, with their reddish stem, a lovely plant that grows where it chooses but I've moved a few of them and they are still growing happily.

Those little light seeds travel so well on a breeze that the plant has 'travelled' widely (using the road and rail network) from it's native Asia and Europe - to become the local pretty weed in many places.

The insects here love it - so I don't mind. Here, we have light and dark pink varieties, along with occasional white ones.
