FLOWER FRIDAY

This plant has been in the garden for over 40 years by the fence and has gotten as large as a tree. When we had to replace the fence a few years ago, we had to cut it back and I saved a few branches and put those in the ground again and 'it came back'... but now after a few years we see for the first time lots of little flowers in abandance. These are little tiny tiny little flowers in a cluster! Miracle happens....in our garden.
And unfortunately I forgot the name of the plant... hint: the branches will grow downwards and will delvelop roots.
