Super-weird plant event

My forsythia are flowering. On September 29.

And although it's not the whole gorgeous bush, it's not one or two flowers, either.

I've never been one for heavy-duty season extension, but I finally seem to have achieved it!

I did check the lilacs, which in the course of the springtime cycle would follow the forsythia, and they are not budding. So that's a relief. Or not!

So, is this really weird, or not? I think it's weird, and the permaculture guru I asked thought it was weird. Readers?

Forsythia are triggered to flower by warmer temperatures after a fairly short rest period of cool weather. New England Indian summers can do it. Is that the pattern this year? Or is it just (not)good old global warming?

... but I have never seen this, not ever. And IIRC there have been warmer Indian summers; I was sitting out in the garden until mid-October last year, albeit with a sweater; and this year it's already been too chilly a few times.

The lilacs have buds, but not flowers, I should say.

agree with Quixote it's been the coolest summer on record in my part of Calli with temps going from mid 90s to low 70s in a few days making harvesting of anything but fun. Flowers are doing all sorts of weird things.

Here's a before the sun raise shot of the gitmo corn growing next to the house. The crop duster shows up at sunrise every 3 days to spray it. Shakes the house.

Well. I have a bit of experience with forsythias. They bloom on last year's wood, so they are simply reblooming, something not unheard of with forsythias. What I do is cut them back to about 18 inches shortly after they bloom in April, everything down to 18 inches, and then I let them grow freeform. They never fail to please the next Spring, and these are two that were downsized several years ago from seven feet. For rebloomng, I guess I would think of this, that September October weather is similar to April May when they first bloom. I believe if you cut them back after the first bloom, they will not rebloom the same season, no matter how mild.

I just saw a forsythia in my local area (Seattle) with a few blooms on it. What's more common here is to see rhododendrons re-blooming, albeit sparsely, in the fall.

Wonder if one could concentrate on breeding plants that have this tendency to rebloom, and obtain a variety which regularly reblooms? Although to my mind forsythias in fall do not seem quite right, that's just my bias -- I associate them so strongly with Spring.
