Stephanotis

This is very pretty.
I like white flowers.:o)

Lovely, love the delicate white flowers of the Gardenia

This is lovely, Maureen; but I'm afraid that it not a Gardenia. I did some searching and it's called 'Marsdenia Floribunda' or more commonly "Stephanotis Vine". How long have you had this? It looks very healthy. You must keep in the greenhouse over winter. Cheers!

Wish this was 'scratch 'n' sniff ' !

What a brilliant idea Gill, maybe in a pendant or something worn around the neck. Lovely idea
