It's really not a good idea to take plants from wild or garden ponds ... for all sorts of reasons ... you will be disturbing the ecology of the pond you're 'robbing' and the plants may bring with them all sorts of 'stuff' (eggs/larvae/disease) that you don't want in your pond.
My best advice is for you to contact Puddleplants https://www.puddleplants.co.uk/starwort.html
They have all sorts of native pond plants which will be ideal for your pond, and they are also a fount of knowledge and advice on setting up a wildlife pond of the type you describe.
However, many pond plants die back over winter and will not be in stock at the moment.
