Lysimachia punctata. No fleas from me. I sometimes stare for ages at a plant knowing I know it but completely unable to recall the name. I find running through the alphabet helps. I do try to get there in the end in a vain attempt to exercise what remains of my memory. The earlier in life I learned a name the easier it is to recall. Which accounts for a lot of out of date nomenclature creeping in.

Thank you floral.

Once I saw the name, guess what? Out of the archives it sprang, reminding me that I grew this, some 40 odd years ago, in my garden. Durrr!
