J. polyanthum hasn't bloomed.

I grow this plant in the greenhouse in a raised bed of loam, well amended with peat and compost. I have lots of vegetative growth, but no blooms. The plant started as a little 2.5" pot from Logees and now covers a 3 x 6 foot trellis. Pictures of this plant in PlantFiles and catalogs show tons of blooms but for me, after a year, nothing.

Any thoughts? Just more time?

It sounds like it put all its energy this year into growing big so I would give it until next year. I don't have this jasmine, but I had Jasminum x stephanense, which I believe is a hybrid of J. polyanthum and J. officinale? and it behaved similarly. I got it two years ago from either Logees or Kartuz in one of those teensy pots, planted it, first year it grew a lot and gave me one puny flower, then the 2nd year I sold the house before it bloomed, but it looked like it had a lot of buds on it. It'll probably take a couple years though before it gets to the full-flowered glory that's shown in the catalogs. I would also watch fertilizing it next year...if you give it too much it may put all its energy into growth again rather than flowering.

I also have the J. polyanthum and its doing the same as Stressbaby's. Lots of growth, no blooms, but this is my first year with it. The same for the J. offinciale ' Fiona Sunrise'. I am about to stick the Fiona Sunrise in the ground and experiment with the cold hardyness of it, its supposed to be hardy to zone 8a, and I'm 7b so why not. I have two of them, so will bring one into the greenhouse in the late fall. Has anyone else had success with this jasmine in the ground in zones 7b?

Also. can you whack these two vines back to about 6"? They are very vigorous growers! I was going to cut them back in late Sept....or after I bring them in the grhouse? or do they bloom in the winter? I am a little confused about when they bloom.

Polyanthum does start to bloom in late winter so cutting it back might not be too good for getting flowers. Officinale I think is a summer bloomer so that one might be OK getting cut back. Only possible problem (and I don't know if this is the case or not) would be that if you cut them back, then they might spend most of their energy the following year growing new stems and leaves vs putting on a great flower display. I think cutting them back severely from time to time to keep them under control is fine, but I do think you might sacrifice on the blooms the next year so it might not be the right thing to do every year.

Thanks ecrane for the helpful info. I was hoping to avoid this scenerio....a large vine going crazy all over my other tropicals in the greenhouse-these really do grow fast! I will have to figure out a way to keep it off the other plants and on it's trellis.

tigerlily, that's my fave jasmine. I cut mine back just after it blooms (you can cut it back to the ground). For most of t his really vigorous tropical stuff that blooms in early spring, follow the rule for cutting back Chrysanthemums - pinch or cut before July 1. Feed when you cut back.

Mine hasn't bloomed yet, so are you saying that I missed the boat on the blooms this year and should whack it back now? I need guidance with this buddy....lol

In your first post, you mentioned J. polyanthum and J. officinale. JP is a winter/spring bloomer, so if it hasn't bloomed yet this year then I doubt it's going to. JO is a summer bloomer, so maybe don't give up on it just yet.

lol the officinale is already in the ground!! It is climping up this fence like it was born attached to it...

So you guys think I should cut it back??? The JP that is? Okaaaaay, I'll do it. Thanks for the advice
