Mesembs say Meh to cold
Haven't been watered since Hurricane Sandy, and still sitting in the greenhouse while exposed to nightly light frosts, these guys just keep on tickin'.
On a side note, I don't recall ever that I haven't experienced a real freeze this late in the year. Most of my plants are still outdoors exposed to the elements or protected from rain in my greenhouse, without heating. Coldest it's been so far is 30F.
Argyrodermas in bloom
Fenestraria with buds
Fenestraria already blooming
Even Frithia is misbehaving, out of season
Not a mesemb, but this euphorbia behaves the same
