I now have 2 plants covered in buds. The first ones have been blooming for over a month. Pollination is tricky but I've some beans too!! These took a little over 2 years to bud.
In the size department, my old planifolia is about 25-30 m long… (guessed from latest measuring + approximate growth in 2 years). I have to repot it, maybe I'll be bold enough to measure the beast… (I guess I'll cut it, some parts are not that sexy)
