An outside chance, but has anyone here tried growing this from seed? No
problem with germination, but despite regular watering and misting it is the
worst seed I've ever come across for retaining the seedcoat after
germination, and choking the first leaves and/or stem. I've had to resort
to cutting the seedcoat away with fine scissors in order to save a few
plants.

Does anyone have other suggestions for dealing with intransigent seedcoats?


Probably needed cold stratification to start decomposing it, Lovely plant
though so hope you are succesfull!
