Oh yes, thats the Samual Summer Gradeflora, it has been flowering for years now, most of the year round. It was a fancy expensive one when it wasn't very big, now it is huge, as are its flowers. We have another one that was a cheap garden centre one, also now massive, also flowers all year round. the flowers if anything are more impressive on that one, but they hardly smell. The Samual summer really smells like a magnolia, it is fantastic.
I never knew anything about gardens but we got this house with a biggish garden and we left it for a few years. It was big and empty. Then I thought, I know, I will plant a few trees around to make it less empty, I like trees.
So I did. Turns out they grow.
