Night Blooming Jasmine

Asked October 5, 2018, 9:39 PM EDT

A friend of mine has a huge (7 foot) night blooming jasmine. What are her options in saving this plant over winter? We decided that her garage wouldn't be warm enough. It's too big for a place in her house. Can cuttings be taken? What suggestions do you have? Thank you.

Thank you for the question. A fun fact: nIght blooming jasmine Cestrum nocturnum isn't actually a jasmine. It belongs in the nightshade family along with well known plants such as tomatoes and potatoes. The white berries formed after blooming are poisonous and should be removed.
This is a very tropical plant, hardy only to zone 8 or 9 so your friend will have to overwinter her plant in a cool area that doesn't freeze. If it's currently too big to overwinter in a bright, cool (60's) room, then her only options are to cut it off to a suitable size or to take cuttings and hope that they root. The following 2 websites explain softwood cuttings for propagation
If your friend isn't worried about removing bloom buds, she can cut it back hard and treat it as a houseplant this winter, moving outdoors gradually as the weather warms up next spring.

Thank you for contacting Extension.
