Winter Solstice Blooms

December 21st. Winter solstice and my plants are seriously confused. Here is a list of blooms happening on my porch right now:

Heliotrope
Potato Bush
Jalapeño
Bird of Paradise
Oxalis
Geranium
Pink-flowered vine thing I can't remember the name of
Aloe

So here's the question. Do you think they are using up all their blooming energy they should be storing up for spring? Maybe I should fertilize them more than normal. Hmm...
