Any idea

[Cassimin]

Has anyone any idea what this plant is and how I care for it?
The flowers are lovely but it looks like they are all dying.

It's a Calceolaria - no idea which one! Some are alpine, and others from warmer climes than ours. They are not hardy outside, usually grown as decorative pot plants, but can also be planted outside in summer. I think they can also be rather temperamental. Burnoose Nursery seems to recommend an ericaceous potting mix for them so they probably don't like calcareous soil.
Sorry I can't help further!

Brilliant, thank you so much.
Bought it from b&m as the flowers were lovely.
Looks like we’ll only be able to enjoy it for a few more weeks.

Not many plants are in flower for more than a few weeks.
