I've wondered about this for a couple of years now and thought that perhaps we have so many different varieties that some are designed to appear earlier?

I'll take this opportunity to rage about daffodils. Most now are not native species, but garden varieties that have escaped into the wild or deliberately planted. Instead of "my heart with pleasure fills" my reaction is "my bloody bile rises"! The RHS writes:

"Apart from the Tenby Daffodil (Narcissus obvallaris) and the Lent Lily (Narcissus pseudonarcissus), which are thought to be native to the British Isles, daffodils actually come primarily from the Iberian Peninsula – Spain, Portugal and Morocco. The flower has been cultivated for thousands of years, often for medicinal rather than ornamental use and been spread worldwide by humans. The Romans are known to have planted daffodils in memory of loved ones or comrades fallen in battle, and are thought to have introduced them into Britain."

Might be and I remember seeing them flowering in Nicosia in January or Feb as their temperatures are same in here during late March to April values.  It seem in the future it mght flower here during Jan and Feb.   The one I have is regular yellow ones.

The most reliable early daffodil is Rijnveld's Early Sensation - a standard size daffodil, not miniatures like Tete a Tete which often flower in February

In milder winters, or in particularly sheltered gardens, this trumpet daffodil can be in bloom in late December or early January, so if you want an early start to the season, then this is by far the best one to choose. It flowers a good few weeks earlier than many of the other big trumpet types, often producing blooms before the foliage has had a chance to reach its full height.

But in sheltered Chichester we had daffodils in flower at Christmas 2015, and I don't think those were specially bred varieties

PS I fully support Roger's diatribe against mass planting of cultivated varieties, such planting will swamp the DNA of native daffodils. Not a new problem -this from 2003

Eventually it will be like in Nicosia that flower in January as their average is was old 15 now 17 to 18 so here might be following this way and become permanent flowering every January as our average continue to rise to low 10s compared to old 6 average before. 

Lao Tzu captured the point elegantly.

"Do you think you can take over the universe and improve it? I do not believe it can be done." 

Why oh oh why oh why ad infinitum do those ignorant folks plant them in these places? The first nooky nook, perhaps? In memoriam of Fred or whoever? Many more possible reasons. But misplaced IMO. Why not for the first, a wild Eglantine rose with its delicious apple fragrance and hints of Aphrodite.

I’m sometimes tempted to take a spray bottle of Roundup and dose hybrid daffs up, before or just after flowering but that runs two risks, being seen or dosing myself with a noxious cocktail. 

And lastly Lao Tzu. Well yes to a point and he was mortal too. When I was in the garden business, I called my horticultural methods the Garden of Eden Approach. But Perfection is impossible for us mortal souls though I believe you have to try. Even places like Sissinghurst or Mottisfont have their imperfectness but they get pretty close to Enlightenment at times. I still approach my current garden in this way.

My first Paper Whites (early daffs) are now past their best. The next batch will have water at the end of the month to get them going in the living room. 

"Snowdrops are not native to the UK, although exactly when they were introduced is unclear. It’s thought they may have been grown as an ornamental garden plant as early as the 16th century, but were not recorded in the wild until the late 18th century. The snowdrop’s native range is mainland Europe."

I had a bit of a run in this year with a 'wild garden' though I won't say where. I suggested several native species but the idea was turned down. "They might have once grown there but if there are none in the area today so you can't plant them". A bit of a fall out over that and we parted company. 

Edit. The site was heavily industrialised in the 18th/19th centuries but it was still a non starter for me. 

And that’s not even delving into the introduction of pests and diseases. The ‘theft’ of pineapples, avocado and many more from South America to the Philippines and so on. And then the ‘stealing’ by Israel of ‘native’ sic avocados from the Philippines to Israel. That was an interesting discussion (not me, I just learnt and listened) at a high level conference in Manila. I just looked up Francois and Helena Oulmont. Francois brought the conference to a boil which was as it should be. I have to thank him for those lessons in plant introductions forgotten by the locals. I’ll have to email them and catch up. Thanks Roger and all of you with this thread.

Conclusion

The autumn of 2025 was slightly warmer than average overall with a below average number of air frosts.

It was also a wetter than average month both in terms of the actual rainfall amounts and in terms of the number of official rain days despite the fact that November 2025 was the autumn's only wetter than average month.

Finally, the autumn of 2025 started off on a sunny note with a sunnier than average September which carried on the pattern of the rest of the year up until that point. However, we then had an exceptionally dull October followed by a duller than average November and this meant that the autumn as a whole was duller than average in the end with September being its only sunnier than average month.
