I love them too. They are almost neon green… let’s hope that keeps going with the years. Here are few more pictures without the morning condensation. As I said, the plant is tiny, about 15 cm tall. Other 3rd year seedlings I have are close to a meter tall now. I am wondering if I should put it in a pot.
Here are two volunteers that I posted last year when they were still in the ground and are presumed to have sprouted in or about 2019. For each pair of photographs the first is May 2021 and second is April 2022. (There is slime in the leaves of the dissectum and they look a bit chewed, I think I have climbing slugs or snails?)
