Burkwoodii is paler than park farm, so I would plump for that. Carlcephalum has rounder leaves.
So long as you leave the thicker stems, it will be ok.
You're right hostafan, some flower buds in there. Maybe wait until it flowers and then slaughter it.
I'm going for the jungle look, hence wanting a vegetable T. Rex
Slaughter it back to the thick stems. It will regrow,lots of whippy shoots, summer prune them back by two thirds, then next February cut back to two shoots.
I made a home for lacewings in the bug house. Roll up corrugated cardboard, and stuff it into a 2l pop bottle, cut down to the straight sided bit. Lay it on its side in a sunny protected position.
I'm growing Ricinus communis instead. They are erupting in the propagator now, will soon need bigger pots.
I tried three nurseries for that last year. It was listed but they had none.
I have clayey soil where they have gone, I dug in a sack of peat and some sharp grit to help drainage. They flowered last year and have come up again this year.
I worked out why you thought it was a kids dose. The buccal form is used to stop an epileptic fit in children. Different use hence different dose.
I'm off to work now. I'll pop in at lunch time.
