Oh dear.
A quick tour of my so-called jungle garden (i.e. the place I so optimistically planted up with climate change anticipation plants last summer) reveals I didn’t exactly get out of the recent cold snap scot free.
This is (or was) a purple cordyline. I was rather fond of it as it made a snazzy contrast with the libertias and hostas, to say nothing of a canna behind it, and gave me the pleasant illusion that I was quite good at putting plants together. I thought they were meant to be bone hardy, too.
The remains of a Melianthus major that was just getting into its stride last autumn…

…and my poor Astelia chathamica ‘Silver Spear’, lately of Chelsea 2008, which also looks to be less hardy than you would think.
