Thanks.
That is truly a fascinating conundrum.
From what I read the gibberellins have species-specific effects. From the internet (so taken with a pinch of salt):
"Gibberellins (GAs) affect flowering in a species-dependent manner: in long-day and biennial plants they promote flowering, whereas in other plants, including fruit trees, they inhibit it."
However, this may also be interesting: "Gibberellic acid is a very potent hormone whose natural occurrence in plants controls their development. Since GA regulates growth, applications of very low concentrations can have a profound effect while too much will have the opposite effect."
Perhaps my dosage was high and I ended up having the same effect as the ancymidol might have done?
How exciting! Now I have to get my hands on some ancymidol for a comparison experiment.
However, remember we discussed the effects of light? (I saw more scapes in the darker planters than the sunnier planters) it may also play a role:
https://www.nature.com/article...
"A NUMBER of long-day responses are induced by the application of gibberellic acid to plants growing in short days. These include the promotion of stem elongation and flower induction in long-day plants1;"
I have no idea what a "long-day plant" is, or whether a daylily is in this group.
