Midsummer to late fall is not their high point. :-) I've always wanted one but...intense allergies and a dislike of strong scents have kept this one off my list. When my corn plants bloomed, I was happy. Then I smelled them. Out came the shears.

Alas.

This one is actually one of my favorites. It is a strong seasonal bloomer. Mine would usually flower around March or April, no other times.

Very pretty! 😁

I have several types of Jasmine - not this one particularly. Spring is when they will bloom profusely. Some bloom at other times too but not as enthusiastically . You can collect the fallen blooms (they fall easily) and put them on a shallow tray/plate of water to extend their life for a day or two. In India it will be common have small plates with jasmines and other fragrant flowers around the house. My dwarf gardenia is also producing buds now and getting ready to bloom soon.

The scent of this species is fantastic. We can grow it outdoors in sheltered spots. I discovered that small ones were cheaper at the florists then at the garden centre and bought a little one for a pot. Sadly the buds it was setting were killed by a few days nasty cold we had recently. But the foliage is fine and far less ratty then J officinale, which got badly shrivelled, and I’m sure it’ll flower in due course. They seem to bloom pretty much constantly in sheltered, mild positions. Round here you often see them in light wells or basement areas.

where is the greenhouse??? ... does the info next to your name mean inside the greenhouse its z10? .. or do you live in zone 10?? .. in which case.. why would you need a greenhouse.. lol ..

anyway .... many things are triggered by the inclination or declination of the sun ... not just temps .... so maybe that is a variable that should be considered ...

From what i've heard you either love em or hate em LOL. I really like the sent.

@floral_uk z.8/9 SW UK it is hardy to zone 8 it says but that might mean dies down to the ground?

@ken_adrian Adrian MI cold Z5 I live in Ontario, Canada zone 5b and the greenhouse is zone 10A/B. That's interesting to think about the lower sun levels..never thought of that. Anyway It's cool to watch bloom and grows very fast wen it gets watered ahah.

always default to the base plant culture variables.. when trying to riddle something out ...

generally those are .. sun/light .. water [including drainage]... temps ... and nutrients ... i may be leaving some others out ... but im not writing a thesis ... eh???

so.. in my ground freeze MI ... first the ground has to thaw ... so thats soil temp ... and then the soil has to warm to root depth.. for the dormant plant to become active.. to initiate growth ... by which time the sun is back up in the sky ... which of course is what warmed the soil ... so once the leaves come up on stored energy ... the sun can take over to produce new energy ... see how the base cultural variables work together ...

so now look at a tropical plant in z5 .. in a greenhouse you pray to god stay temperate enough .. lol ... so variable one.. temps must be insured ... but even these plants will go into slo motion up here.. because winter sun might be so weak ... and what slo mo plant needs a lot of water.. or even fert ... so you usually back off on those... unless your eating up water because the greenhouse is baking hot ....

very basic.. i hope no one wastes energy arguing about this.. it isnt a thesis ... [i said arguing.. adding to it.. is just fine with me] .... its to make you think about the variables.. and help you in the future figure out why something might be doing something out of phase ...

so what i might do ... if i were curious enough.. is to find out what native cycle the plants would be on in its tropical zone.. and try to figure out which one you are manipulating that is causing the weird timing ... and others above might have mentioned such.. and i didnt read careful enough ... like maybe it got cold in fall.. before you put n the heat... which triggered the flower cycle???

now go write your own thesis ...

No thesis, but note I said these things are often grown in light wells and basement areas round here. And they're evergreen under our winter skies and are in bud or flower almost continually. They clearly don’t need blazing sun.

Matt: Also consider in tropical , sub-tropical regions the transition from winter to spring is the "Time" when most perennials will flower. This is especially true for plants that produce fruits. It gives them ample time during upcoming warmer/hotter months to grow and mature. The seeds will make it back to ground and there is ample warm months left to sprout and grow new ones. There is no adaptations for dormancy, seed stratification etc. The whole cycle can happen in a single year.

Eg, for Citrus, mango, guava, pomegranates, etc this is the primary season to flower. And so it also primary flowering season for many perennials. Some of these may flower at other times too. India, for example, Sept, Oct is another good time for flowers - just coming out of the summer monsoons. But those are not as splashy as in Spring.

Thanks for the info!

I ended up finding a great article online. Someone had a greenhouse full on them somewhere in zone 4 or 5.

Can you post a link to article? May be it will be useful to all of us.

Mine bloom once a year. They are blooming right now. March 19th!

I couldn't find the original post but I see it's a little different as far as timing for a few climates.

Logee's article was decent.

The article may be decent but calling it Winter Jasmine is misleading since that common name is usually applied to a different species. An uninitiated gardener would risk getting the wrong plant if they ordered by that name.

J polyanthum round here aren’t in flower yet but they’re full of buds.

I thought J. nudiflorum was commonly called winter jasmine. In our zone that is fully hardy outdoors and deciduous. I have a few bushes in backyard and they have already started flowering. After they flower the leaves come next after a gap. They throw out long arching shoots and wherever the tip touches the ground it will root very quickly. Every year I need to do a cleanup and prune back. Here is pic from a few days back.

J polyanthum is marginally hardy here. I had one outside that survived (sort of) for about 5-6 years.

J parkeri, a very dwarf himalayan jasmine, is also marginal. With protection outdoors it is evergreen. It will flower within a month. Without good protection, it loses its leaves and exhibits branch die backs.

Yes, winter Jasmine is generally understood to be J nudiflorum.

Yes you guys are right but it is labelled on logees site as Jasmine polyanthum. "winter blooming jasmine" not winter jasmine. It's confusing lol I know.
