Spring in Portsmouth 2021

I had a look in my polytunnel on the allotment on Sunday 12 April and noticed my Ophioglossum vulgatum was just coming up. Although not heated this is a rather protected environment, so I decide to check if I could find any plants at Hilsea. Here I found this patch

Also growing in the polytunnel is an Osmunda regalis, which I got from Portugal, along the river Duro. I am not sure if it comes up early because of its ancestry or because of being in the polytunnel. I have grown Microsorum diversifolium for many years both in the polytunnel and in my shade tunnels. It seems to prefer the polytunnel. This is the first time I have noticed it climbing off the ground
