I ID'd this once before several years ago but cannot for the life of me remember what it was. I recall there was some German connection? I'm in the UK.
It's quite invasive but only in my pots and containers (not the garden itself) so I have to keep it in check but it always produces clumps of beautiful deep orange flowers on tall singular leafless stems with black hairs. Flowering now so late spring/early summer. Leaves are soft almost papery with white hairs. Overall height up to aporox 60cm
I'd be very grateful for an ID 👍🌼
