The late plantsman Alan Galloway was a prolific plant collector in Southeastern Asia, and one of the plants that has surprised us with its winter hardiness is the giant evergreen Solomon’s Seal, Disporopsis longifolia. In the wild, Alan and I encountered this throughout Thailand and Vietnam, but our tallest clone is one which Alan collected in Laos, and we christened Disporopsis longifolia ‘Alan’s Laosy Giant’. Our clump, which has been in the garden since 2007 has topped 5′ in height and is in full flower this week. Sadly, it has yet to produce a single offset.
