Well, well, another one, we've had 3 or 4 ID queries on this in the last day... its Euphorbia lathyrus, common name Caper Spurge, pops up on its own usually dropped by birds, and where there's one this year, there'll be lots more next year. Classed as a weed - if you decide to remove it, wear gloves, the sap is irritant.

Euphorbia lathyris, a seed weed. Watch out for the sap it can cause problems if it gets in your eyes.

Snap!

I don't believe it! Another one!! Welcome to GoY Heather! Good luck to you and your daughter as you get that new garden ship-shape! We have had quite a few of these popping up on the questions pages this week. It must be the time of Year for them! KAren

Welcome to GoY from me too.

the tall plant against the fence with the small white flower is also a weed. called Jack by the hedge, amongst other local names. that could also be pulled up. no irritating sap but a garlicky smell hence another common name of garlic mustard.

Dear All
Thank you very much; I really appreciate your help.

Best wishes

Heather
