Hi, welcome to GoY, it looks like Brugmansia, possibly B x candida, needs a minimum winter temperature of 45f, formerly known as Datura X candida, common name for Brugmansia is angels rtumpets, Derek.

And very poisonous fruits!

Thankyou for your help, we have contacted the company who mistakenly sent us this plant. We are a little concerned about the toxicity of this plant.

All parts of the plant are poisonous. Be especially careful with pets and curious children.

Thankyou Bathgate, we are going to get a rid of this plant as we have Grandchildren and pets, would there be a problem with disposing of this plant safely?

I would just bag it. Leave for collection. Clean that pot real good if you want save it.
