Well don't you DARE tell that (the frost sensitive bit) to the bulbs of it
that I grow. ;-) Maybe we here in Aus have a strain that doesn't mind
frost but my 2 bulbs of it even just took without any problem an
unseasonably early -5 followed by -6'C the two mornings over the weekend.
So many other things got hit badly as this is VERY early for that hard a
frost here and a lot of things were still only closing down for the winter
and hadn't completely hardened off (so to speak). So many plants in our
garden pulped to a certain degree that would normally easily accept -6'C
later in winter when they have prepared for it. Even with this early low
the Urginea maritima are doing just fine and not looking like they've been
damaged in the slightest. Big healthy leaves are still there, having
emerged in teh last month or so and still growing.
They went through last winter fine as well, taking -8'C as well
