So, after reading an Anne Rice book and hearing her mention the smells of jasmine and bouganvillia in New Orleans, I was inspired to try to grow night blooming jasmine myself. It's a tropical plant but research said it can grow in NY, so I bought a small plant online and it's been growing like crazy. I do have some questions though. It's not flowering. It was just 3 inches tall when I got it but over a foot tall now and it has huge beautiful leaves, but no flowers? Why do you think it hasn't bloomed? Is it the weather in NY? I mean it is summer and it's hot and it is growing, so I doubt that's it. Also, how large of a pot should it be in? As you can see, my pot is small, should I transplant it? Also, should the stalks be supported or let them go crazy? Any other advice for night blooming jasmine in NY?

What kind of sunlight is it getting? I believe that they need a lot of light in order to bloom. Also if you're giving it a fertilizer that's high in nitrogen you might get a lot of growth but not much bloom.

You may want to repot it into something larger and give it some support (although I've read they like to be pot bound, but I'm not sure how true that is). It looks really healthy and beautiful, even if no blooms yet.

You are not growing your Cestrum nocturnum outside, so NY weather is largely irrelevant unless you keep all your windows wide open throughout the winter!

This is a plant that requires maximum indoor direct sunlight to bloom. Yours shows large stem space between the sets of leaves and that is a symptom of less than ideal light. Otherwise, you seem to be taking good care of it.

Move it to your sunniest windowsill. You may want to prune back some of the already leggy stems to keep the plant fuller and more compact. Keep the soil moist and it may need water more frequently as the light improves and the roots expand. Keep it moderately potbound to encourage flowering. It will also have to mature before it is likely to bloom, so be patient.

I agree that your lovely plant needs the highest light possible for it to produce blooms. I have a Night Blooming Jasmine (Cestrum nocturnum) growing in my garden here in Florida where it gets very bright shade in the afternoon and sun early in the day. This shrub does have a gawky, sprawling habit with branches sticking out everywhere.

Ok thanks for all your comments. First of all, I am keeping it outside. I got it in the beginning of summer when it was warm so it's been outside in the sun all day every day. I could move it to a place that gets more sun, but it's not indoors now. I will bring it indoors when it gets colder here in NY. So they like to be potbound but should it be in bigger pot? Also you say prune leggy stems? Is that necessary?

What does moderately potbound mean? As opposed to what? And when will I know if it's mature?

I didn't understand that you were growing it outside in the warmer months.

A moderately potbound plant is one that will go 2 or more days without water after a thorough watering. If it requires a thorough watering every day or two, then it probably needs a pot one size larger. Otherwise, leave it alone.

There are many factors that contribute to a plant's maturity, so there is no set time frame. Moving yours back inside in the fall will require you to make some changes while it attempts to acclimate to the new reduced light environment. It will have to be placed right in a very sunny window. Its need for water will decline slowly as its growth rate slows. It may also need to be pruned back. It is not an easy plant to grow and flower successfully indoors.

Same problem with mine. I have planted it before in the ground and they flowered. I moved to a new house and planted it in a pot. Re-potting, root pruning, top pruning and granular fertilizing all in vain. What should I do to stimulate flowering? It's 3 yrs old and in a bigger pot than Berniecharli's.
