Philodendron verrucosum, deciduous?

Are the leaves of Philodendron verrucosum considered to be deciduous?

Recently my P. verrucosum vine dropped all of it's leaves. I thought it was dying.
As soon as the leaves dried up and fell off the vine, the vine began throwing leaf buds and shoots.

I see that the leaf cataphylls are deciduous, but is this normal for the leaves themselves?

This is the only species I have that did this, and it was under normal weather conditions. I have only had the vine for about 1 1/2 years.

I would like to know the answer to your question as well Dave. I thought I had lost this particular philodendron last year but the plant renewed itself for me here.

I have also seen this happen Dave. My large plant droped almost all just three weeks ago after I redujced the amount of water for the winter. Right all are starting to grow again.

Thanks Rachel and Steve!

Maybe something to do with changing daylight hours?

Could be since they don't experience shortened days in their natural habitat.

Thanks Steve.
