A seedling pot.
going to go with something like pipe insulator wraps.
I was really stumped by last week's - thought it was part of a coffee maker!! This week's not sure either but am going to guess its one of the tubes in a bee (or insect) "hotel". Great photos of the bee flies and Peacock butterfly by the way.
is it a loofa plant? (I'm sure I'm wrong but it was a guess)
Thank you for visiting. Hope you enjoyed the pictures. Any comment, or correction to any information or identification I get wrong, is most welcome. John
