Does someone recognise this plant, dipladenia spalier? I have just bought one but have not been able to find any information about it, eg where do I plant it and crucially how big will it grow?
It's more commonly known in the UK as Mandevilla https://www.rhs.org.uk/advice/profile?pid=713
A lovely climber - tender and best grown in a shaded conservatory
Thank you very much for this helpful advice. I have just the place for it!
