I had a single foxglove appear in a tub this year. There are no foxgloves
anywhere in the neighbourhodd that I can see. It flowered well and I moved
it into the garden after flowering.
Now I have another in a different tub looking as if it will flower. I
expected them to have a flowering season, but it seems random.
Any digitalists here?


Sell & Murrell's Critical Flora gives June to September as the flowering
season, but I was recording the species in flower from the middle of May
this year. Peak flowering season is June and July.
