Star Jasmine
To encourage bloom: A cool, bright winter (around 50 to 60°F) sets the buds; a warm room all winter means leaves and no flowers.
Star jasmine is grown indoors for one thing: the intoxicating perfume of its little white pinwheel flowers in late spring. It's a vigorous twining climber, so indoors it needs a hoop, trellis, or support to scramble up, and a genuinely sunny window to set buds.
Light is the whole game - without several hours of direct sun it makes plenty of glossy evergreen leaves and not a single flower. Keep it consistently watered through spring and summer while it's growing and budding, ease back in winter, and prune lightly after flowering to keep it in bounds.
Needs several hours of direct sun to flower; in low light it stays green and refuses to bloom.

Feed with a high-potassium feed to support flowering

No flowers almost always means too little direct sun
