Cyps in cultivation to date: the true dirt

[cxcanh]

Last few months I also found Cypripedium lentiginosum in Vietnam and this is new record for Vietnam (just published end of October 2023).
So in Vietnam we just have 2 species in this genus and both are very difficult for cultivation and both of them are grow in the altitude from 1.600m above sea-level

Thank you for your wonderful documentation. The observation that Cypripedium subtropicum inhabits altitudes of 1,600m is consistent with my initial success in the air-conditioned zone of my greenhouse (seed-grown stock from Hengduan Mountain Biotechnology).
