Not aware of an orange one although midwinter fire can be orangey/pink. Maybe you're thinking of the willow....Salix alba 'Chermesina'

There are quite a few, all varieties of Cornus sanguinea. Look at C. sanguinea 'Anny's Winter Orange', 'Winter Beauty' and 'Winter Flame'.

Also Midwinter Fire

I saw an orange one walking the dog this morning. However until leaves come strictly speaking its difficult to tell.

"An orange one walking the dog" puts me in mind of the dog who always chased the postman on his bike - until they took his bike away.

Thank you so much for your replies about orange dogwood. I will go to the garden centre and see if they have any of the ones you suggested.
Thanks again Joan 25
