Hi Welshtiger, I think the Jasmine you have is the one often called Stephanotis floribunda and sometimes (Madagascar jasmine)
It requires good indirect light (not full sun) and a minimum growing tempreture of 17 oc (63 of) and 13 oc (55 of) in winter.
The compost should be kept moist but reduced in winter.
Regular feeding is important for bud formation, choose a pot-ash rich feed to stimulate the flowers to open, feed as instructed.
Trim lightly after flowering. Good Luck Tbird+
