I think there is a 3' pot in there...

The plant has just been growing on itself for years.

Culture tips, dry cold rest in winter. Heavy watering upon the warmer days. Going from really dry to really wet seems to be a factor.

Is it your plant? Don't think your greenhouse looks like that one.

Thanks for the photos.

Nope, my boss has been growing that plant for a very long time. Consequently, it is also in the greenhouses I work in.

Hi, I have a tiny start of this plant. If only it would grow to look like yours! Could you give us some cultural tips? Thanks a bunch...
