FWIW, its really hard to say what might have caused your spike issues. Change in weather maybe?

Id say just make sure your plant is isolated from drafts and temperature differential. Eg drafts of cold air into a warm house. Then study it closely over time. You'll soon learn what local conditions trigger flowering. Sometimes spikes start early and abort for whatever reason.

At a certain level the daylength/temperature debate is a bit academic for folks living at more extreme latitudes. The light and temperature change at the same time and if the plants conditions are dominated by your local conditions (eg they aren't in a grow room or light supplemented greenhouse,) then they will respond to whichever of the two triggers them. What the academic study does tell you is that you don't need to worry about growing your plant in fairly constant temperatures, eg in your home. The light changes are sufficient, they don't need to be coupled with a temperature drop.

threadjack interlude to say that i appreciate your use of the word doorwall, as it exists only in our little part of se mi!

that’s all, sorry mods and everyone, carry on....

I hadn't really thought about that before. It is a door in the sense that it is ingress and egress to the house but it isn't really a wall, rather a window. How curious!

What you said made perfect sense to me until you explained it. Now I'm wondering can I have a picture?

Picture what Pella calls a "sliding patio door".

Makes sense to me: sure feels like a wall when you walk straight into one. :-)

[/COLOR]That's easy enough. Interesting how language can make things complicated. Mine are never clean enough to worry about walking into by mistake.

I did notice today that my new growth has scapes. The old dried up canes usually bloom too, but they haven't started yet. This is the pattern I've seen for years when the new growth matures it sends up a scape. Others follow later.

What is a "scape" in this context?

The part of the plant that holds the flowers. The bloom "scape."

Any chance of a photo? I'm not clicking even after rereading the botanical definition of scape over and over. :-)
