Just seems a bit odd that everything has decided to flower at once
It is if you try to explain why... I guess it stays a mystery forever as long as it can't be intentionally reproduced.
I did grow some Bucephalandra sp. for about 5 years and only one plant flowered for me once and never again.
Also growing a load of Anubias for over 6 years now I regularly see people showing flowering Anubias, mine never did.
I had a waterlily in the garden for years and it always did suffer a bit never grew to full potential and never flowered. Then I gave this plant to a family member he did put it in a tub in his garden. The first summer after that I get a picture of it flowering?... And he did nothing special to it... I have no clue what I did wrong and what he did right. Maybe he has different water from the tap I have no idea.
There are some studies going on about plants communicating, there is some evidence that they seem to be able to. But it's still a mystery how it works... They seem to do it in symbiosis with a subterranean network of certain fungus strains and bacteria. And maybe also with feromones over the atmosphere.
It might be the biological phenomenon we know as
positive Allelopathy. Meaning that a flowering plant spreads allelochemicals that induce other plants in its reach to do the same thing.
Let us hope science will find a conclusive answer in our lifetime.
That would be awesome... We are already halfway with acknowledging it exists, the next step is how and with what!?
