I've read that Orchidioides / Iperua seed have a short shelf life in general & U. humboldtii & U. nelumbifolia probably mark the lower end of the range with their 'special' seeds. It looks promising for me to have some U. nephrophylla seed in the coming weeks (& possibly U. longifolia seed in a few months). It seems that this type of seed rarely makes it into the ICPS seedbank for distribution & I was wondering if this is due to overall scarcity or to short viability (or both).
Does anyone have any ideas how long seeds from these groups remain viable?
