Hello Richard,
To my knowledge this sp is not currently commercially grown,
it is so site specific as regards to its natural habitat of acidic bog that it is quite difficult to grow. It has been discussed that bulbs might be monocarpic, dying after flowering, leaving behind offsets and seed to carry on future generations.
it is however stunning and I have myself been trying to find bulbs/seeds for at least 10 years now without sucess, but if I do find any, I will let you know
