Mexican wedding blossom or something like it that it is called! I'm sure that someone can come up with the right description! I like to see the other places too around this beautiful bush!
What a display of lovely white flowers Beryl....I can see Gary there too..... must be bin day today! You have walls separating the areas of your garden....it almost looks like you are next door!
