@ZoobZoob_farmZ,
Yes it only flowers once (and takes about 20 years), very suddenly grows very big trunk, then it dies.
Those flowers were bright yellow/orange, but because it was very cold at the time (as cold as -6c, mid-winter, July last year), they went black later.
Apparently it has very interesting sugar/syrup in it, used for cooking or wine. I didn't know that then though.
Love this, I was actually wondering if people posted other plant diaries besides cannabis on here, and this confirms it for me! 😄 I was considering documenting some of my other garden dwellers.
