If someone were to give me a plant from Mexico, my first impulse would be
to crank up the heat for it. But I want to say again that the plant I have
of Manfreda singuliflora has gone through two winters here in an unheated,
leaky coldframe. Last winter we had a six week period when the daytime
temperatures did not get above freezing - in other words, for six weeks
24/7 the temperature was below freezing - and this was, for the most part,
without significant snow cover. Because the cold frame in question was
packed with plants, the light (lid) did not fit tightly: any breeze would
have swept out any accumulated warmth from the sun. Yet Manfreda
singuliflora survived and went on to bloom. 

Pasadena in the winter must be pretty toasty compared to Maryland, right? I
can't help wondering if some of those sulking Manfreda might benefit from a
bit of real winter. 

Lee, you also mention two species which are only now coming out of
dormancy. I have a plant here, acquired under the name Manfreda virginica
but so far unproven, which is also just now coming out of dormancy. Well,
that's not quite right. It started to expand months ago, but has grown very
slowly: even now it looks like a newly awakened plant. Typical Manfreda
virginica growing nearby under similar conditions expanded their rosettes
months ago. This pokey plant seems much stouter than the others.

Maybe Pasadena and Maryland have something in common of which I'm not aware.

Manfreda virginica are my favorites.
