its a type of euphorbia and you can use the seeds in salads etc. I just cant bring the name to the fore front of my brain. not a weed if you want it.

Caper spurge is the common name finally brought it to the front of my mind. :o)

Thanks for your answer.... I will leave it in the ground.
Many thanks. Higgiwiggi

Yikes, Sbg! I wouldn't use the seeds of Caper Spurge in salads--the sap is very caustic! True, edible capers come from a very different plant.

And it is a seed weed of the first order. Let it flower and you will have them growing everywhere.

I've never eaten them, I guess that is the trouble with common names.

Gosh you are so right Tug. That's the danger with common names. You are correct all parts of the Euphorbia are toxic.

If you do decide to pull it out wear gloves. the milky white sap is caustic and when exposed to sunlight it can cause nasty chemical burns.
