Mock orange in beautiful full flower! Many yellow leaves -- must be Gold Leaf Mock Orange!

I can't remember if it flowered last year, but my post on May 22nd 2001 commented on how horrible it was looking.

This year the flowers are gorgeous and smell amazing, lots of bees and flies etc. visiting the flowers.  However, most of the leaves are very yellow, like last year.

Oh, wait!  Google says there's something called a "gold-leaf mock orange", and the photos look similar to mine!  This must be what it is!  Yay!

This post talks a bit about pruning it, removing the oldest stems, etc:  https://awaytogarden.com/great-shrub-gold-leaf-mock-orange/
