Thanks Michael. That is very useful insight. Unfortunately, I have no ground to grow anything in and my balcony gets very little sun after August/September as the sun moves lower. The polyanthum is attractive in that it blooms during late winter early spring....

I agree with MIke. Mike good job

I ordered everything other than the the officinale. I like the polyanthum challenge. I have managed to get kalanchoe, poinsettia and an evergreen Azalea to rebloom so....
They are all 2-4“ starters so t will be a while before they jostle for space on the sunny windows...

Here's the first bloom on my "hardy Jasmine" (J. officinale).

The strength of the fragrance is between weak and moderate (smells more "moderate" if you put your nose right up to the flower). It has a fragrance reminiscent of honeysuckle, but also jasmine-like. Maybe a very slight "green" floral nuance. This jasmine is probably best in climate zones 9a to 6b. It's more cold tolerant than the other jasmines.

You don't have officinale there! That is Jasminum grandiflorum, the Spanish jasmine. The leaves give it away, and the flower is much too large and too 'rounded' looking to be officinale. It's also much less cold hardy. Definitely worth growing, though! Look up images of Jasminum officinale 'Fiona Sunrise' to see what the leaves and flowers should look like (although Fiona Sunrise' has gold leaves, the shape is typical officinale).

There's a tag on the plant that says "Jasminum officinale".

I also previously bought a Jasminum officinale plant from another source, which I am sure is Jasminum officinale.

I took a picture so you can compare the leaf shape. The one on the left is the one you are disputing, and the one on the right (labeled "J. officinale" in the image) is the one that I know to be Jasminum officinale.

I'm certain the plant on the left is grandiflorum. You will find that the stems of J. grandiflorum are stiffer than J. officinale, the fragrance is different, and the leaves will be evergreen. Adding to the confusion: there is a cultivar name Jasminum officinale 'Grandiflorum'! This one is a large flowered form of officinale (Xera Plants lists it) but sometimes the name is applied to the 'single' flowered form of J. grandiflorum. The double flowered form has an extra petal or two. Logee's lists both in their catalog. The most important thing to remember is hardiness. J. grandiflorum can't take temperatures much lower than the upper teens, while J. officinale easily handles temperatures near 0F.
