Good question Cohan. One the positive side, Allium thunbergii is very cold tolerant, not bothered by some degree of freezing temperature and even some snow, they'll go as long as they can. On the other side, I once had a form of Allium thunbergii, and a Himalayan species A. stracheyi, that could never successfully bloom here in New England, because they would try to flower in December. I had both of these when I lived in mild Pacific Northwest (near Seattle Washington), and in that climate they did indeed bloom in December without problem, but here in New England, by December the ground is frozen and all plant activity is stopped.

Two views of the Seven Son Flower, a small Chinese tree, Heptacodium miconioides (syn. H. jaminoides), introduced to cultivation in North American by Arnold Arboretum (near Boston, Massachusetts), around the early 1900s. It is very hardy and ornamental, flowering in September with clusters of small white flowers that are scented like jasmine or gardenia (drives the bees into a frenzy), but the real show is after the flowers, when the calyx lobes expand and turn a bright pink to red color. The tree also has pale shredding bark, and handsome peach-tree-like leaves, a really good tree all around.
In this photo taken on October 5th, the transition where there are still white flower clusters and developing pink bracts.
Two photos of the bracts more fully expanded, the darker one on a drizzly day, Oct. 12. The bright one taken yesterday in sunshine, where the bracts seem to glow.
I guess it would depend what cues are triggering flowering- day length, day/night temperatures, or number of days of growth!
Seven sons looks like a nice addition to the fall garden, atypical colour scheme for that season..
There are still some things flowering here, but they are definitely on borrowed time..

A couple of views on the road yesterday...
Biiiiiiiiiggggg skies there Cohen.
in Devon, UK Zone 9b
Indeed, David- at least where there is cleared land- my property has trees all around, so we can only see the sky more or less straight up..lol
Potentilla nitida with some 'lost label' semps; the seed batch of P nitida from several years ago has been interesting- plants are quite varied- in greener, more silvery, flatter, taller etc.. Still no flowers :( so i can't comment on those.. This is definitely the flattest of all, perhaps smaller leaves, that would require a closer look.. a bit of fall color on this one.. Oct 07
A different kind of (ex) Potentilla- Dasiphora fruticosa hybrid/cultivar.. I picked up a couple of these (different) late a couple of years back for $1.00 each, and although they are in a dry spot with rare supplemental watering, they have been doing well, if going slowly. I might still have the names around somewhere, if I can find the plastic nursery tags...lol This one is a very nice creamy palest yellow, the other is white.. We have a large typical yellow on the property, and I still really want a pink flowered variety! Oct 07 some nice subtle fall colours too.
A more standard D fruticosa.. this seems taller and looser than modern cultivars, could be closer to wild forms, or its site which is sunny, but not all day.. this shot from Oct 13. all forms seem to flower well beyond frost...

Cohan, I think my favorite is the smaller cream potentilla (I prefer that name!) and not the yellow one!
Nice Crocuses, Lori, autumn flowering crocuses often get damaged by the rain here!
Here is a nice plant still flowering. It has been flowering for several months now but only with 2-4 at the same time. It is a perennial here.
Impatiens arguta (I think).
Rogaland, Norway - with cool, often rainy summers (29C max) and mild, often rainy winters (180 cm/year)!
Trond, I agree- the natural bright yellow is nice, but I love that cream colour.. it should get to a decent size in time too- probably faster if I watered it, and I will try to next year, but the spot I have these (the cream, a white, and a Prunus tomentosa seedling) is a bit beyond my hoses, so I will have to carry water- or get more hose! I do make a point of throwing some extra snow on them in winter- they are only a few metres from the driveway, and they have a thick mulch to hold whatever moisture the do get, but the spot is by two old spruce trees, and at the 'high'/dry end of the property..
The Impatiens is nice, seems to have a bit of colour in the leaves too. I planted a few seedlings from my cousins place of one of the big invasive Impatiens, in my first year or so back, but I didn't choose the sites that well, and they didn't grow..lol
