Hi Steve,
I grow these Crinums (apart from Hana) in a warmer location
equivalent to zone 10. C. xanthophyllum is by far the most
temperature sensitive of all of these and without warmth in winter will
not even survive in a cool glasshouse in zone 10. All the remaining
Crinums will grow outdoors in my zone, but C. augustum and asiaticum
are susceptible to frost burning all the leaves during winter, even
though mature plants will survive all but severe frosts.
The Southern NSW variants of Crinum pedunculatum in grow in the
wild in mild frosts areas and will manage all but prolonged frost
periods or severe frosts which will damage all leaf tissues.
The North Queensland forms of C. pedunculatum are from the Australian
tropics have thinner textured leaves and are no different than C.
asiaticum or augustum in there ability to manage winter conditions.
Cheers
