The aliens have been at it again
Caper spurge. Euphorbia Lathyris.
The sap causes sensitisation of skin to sun, and will cause burns, so remove using gloves.
1st one an aeonium
2nd Lychnis coronaria
3rd one a candelabra primula, possible pulverulenta
Not sure of last one.
Does it smell oniony?
top one is an opium poppy, paeoniflora or double type.
I think if you dead head,the plant is stronger for next year, but I save seed off of a lot of mine, so I only cut down the ones I dont want to seed.
Yes that is a weed. one of the chenopodiums.
cherry laurel? Prunus laurocerasus
Big leaves so would rule out both privet and philadelphus.
No. I find that once the flowering shoot has gone up from the basal rosette of leaves, it makes no difference. They are not repeat flowerers.
Daniel has posted but doesn't tell us anything other than it was a "cooling off period"
We still don't know what was the problem. If we don't know, I suppose any of us could be in the same position.
