Help identifying growth on Star Jasmine

[Priscilla]

Hi all,

I have 2 Star Jasmine plants that I bought as fairly mature plants. They're currently growing along a South facing wall and have bloomed a couple of times now. I've recently noticed these white brush-like growths along some parts of the stems of both plants. Wondering what these are and if I should be concerned.
First time caring for Star Jasmine and would appreciate the help. Thanks!

Those look like roots. Tomatoes do something similiar. Wanna propogate? That is the point of interest.

Thx! I did wonder if they were aerial roots but never seen ones growing like that before. I looked again today and noticed that they only appear on actively growing shoots... No sign of them on the mature parts of the plants which makes me think these could be climbing structures?
