What is this please?

I'm not sure. I'll give it a try when/if it comes up this year. It's just occurred to me. The leaves you can see in the picture may actually be of another plant.

 

Nim, your flowers do look like they are coming from those leaves, which is what is throwing us all I think.

My only other offering, which I'm not entirely convinced of, is one of the Iberis (Candytuft) family ....

 

Well, Googled it, and whilst it is very very pretty, and I think I need to get some for our front garden lol .. it's not the same thing.

This is so weird isn't it! I do find it odd that I manage to have something beautiful in my garden, yet have no idea what it is or where it came from lol. Typical me really!

I think I'll need to wait a few months and see what is coming from what and then come back to you guys with further information
