The same is somewhat true in the US. However, right now there are several places selling this form of fairrieanum for reasonable prices, including Orchids, Ltd. and Enlightened Orchids.I think the green ones are very rare here in Australia.
P.fairrieanum fma Bolmannianum is not really rare its just that it seems growers to kill it regularly. I think 'Bolero' & I bought seedlings of it from the same source recently. I know Bolero is questioning the potting of them, mine were the same, I'll answer that question in his post. My plants seem to be growing very well & hopefully continue to do so. There are a number of hybridist selfing and outcrossing this plant but seedlings produced seem to be low and you need to be very quick in line to buy them.
