Hi Angel-Face,

I know longer grow Jasminum molle but it definitely grows upright and eventually needs support. You can continue to cut off the long branches to about 2 feet to encourage more side branches but it might be easier just to tie it to a trellis.

Hopefully others who have grown this plant will chime in.

My J. Molle grows to 6ft ht every year and blooms profusely. In spring I cut it down to 2-3 ft ht when I take it outside. I shoots out lot of new growth and then blooms all through summer. I have noticed it tends to shoot out long creeper kind of stems during winter time indoors and does not do the same in summer outside. I have attached the pic of the plant below that I trimmed 2 weeks ago.
