It's got some competition from its potmate, which hasn't yet flowered but is pupping like mad.

Yoko is a beastly flower.

Ryan,

Just the odd diluted taste of regular Miracle-Gro. That, and the emulsion of angels' tears...Maybe I've finally found a general soil mix they like.

Annette,

Yes, you're ready for the support group - we're like the government, we're here to help. That temp shouldn't be a problem for many plants, but I'd find it iffy if my collection was mostly succulent Asclepiads from, say, Somalia. If the soil is dry and they're not in their growth cycle, I'd guess you'll be OK with a lot of things, but I'm not sure I'd want these gasterias (in fact, I'm quite sure I'd not) to be repeatedly exposed to those temps.

Annette, I keep most of my succulents in a greenhouse with similar winter temperatures and some in a larger greenhouse that can even go a degree or two below zero (freezing) if it's exceptionally cold outside, and I've never had a problem. Even some gasterias, like G. carinata, are fine, although like Jeff says, I'm sure it depends on where they are from and also the duration of the cold temps. The succulents I baby and keep in the house where it's warmer are my adeniums, pachypodium saundersii, and a jatropha.
