Here are pictures of a plant I purchased 2 years ago in a 6 inch pot. I was in the middle of a move to a different hardiness zone so I gave the plant to my daughter without the tag and now I have forgotten what it is. On a visit to my daughter this year I made a promise to her to find out what it is. It is growing happily in zone 5b and has survived 2 record cold and snowy winters. It has not flowered since it is in a shady location and may not receive enough sun. Honestly I am usually a much better custodian of my plants but the moving experience threw me off....so any identifying help will be appreciated!
I stand corrected....my daughter just sent a picture to me of one of the lovely blooms that fell off of the above plant.....
Any of the pictures I found following the suggestion that this might be a mock orange do not exhibit blooms that look like the picture she sent me..the mystery continues
