Well it's true that € is very expensive now (interesting for me to buy your plants), but Popow's plants are not very expensive compared to US sources for some plants... Maybe just difficult to get some CITES to export to USA
I think I am most intrigued by the Paph. lowii var. album. I did not know such a thing existed. I have been trying to do searches to see a picture of the flower but have come up empty handed. Does anyone have a picture?
The only thing I could find was a flask of Paph. lowii 'Albino Beauty' CHM/AOS x self for $700, but they did not have a picture either.
