So, if I read your expert opinions correctly, this plant, that has no variegated or round leaves, cannot be a serissa either?

im saying, that it could be a serrisa, but not the variagated type, i think its fortoda or something that is variagated.

#foetida "variegated pink" has double pink flowers and whiter margins on the leaves and foetida variegata has yellow margins
and obviously serissa foetida without any variegation.

It is, without a doubt, a serissa. I currently have five different types. Yours appears to be either "Kyoto mountain" or "Pink Fairy", I would have to see the flower to be sure. It is a serissa. They lose their leaves quite readily when conditions change. I moved mine to the garage for a cold snap and within two days, half of the leaves yellowed and fell off. No worries, when conditions stabilize and if the plant is healthy, it will come back strong. Some think this tree to be a tropical, but in my experience, it is semitropical, and benefits from exposure to cooler temps. I have left mine out down to 35 F with no problems. My cuttings have seen the 20's as I just don't have enough room to move them inside.

Mine has tiny white flowers. And it's doing great, it grows new flower buds I think twice a week. Its form is a mess though as new branches emerge on a rapid pace. Which led me to wonder, is it okay to prune at this time of the year, considering I'm located in Asia?
Or will it be better to wire the new branches instead, to help in ramification?

Thanks!

It certainly is not box. Definitely Serrissa, especially if it flowers. Yes you can prune but wire? Asia means nothing where in Asia?

Sorry, I'm in the Philippines
