Sentimental Unidentified houseplant – Lipstick Plant

Hi Judy, I have been given a houseplant by my dad, that my mum was given by a friend of hers before she passed away. My dad gave me the plant after my mum passed away and I really want it to thrive, however I have no idea what it is or what it needs. I have tried it in various parts of the house, and guessed at watering but it isn’t doing too well. I remember seeing it with very small delicate flowers some times. I would be really grateful if you could have a look and any advice would be glady received.

Many thanks
