Plants occasionally "get confused" and bloom in the wrong season, especially
if there's a temperature sequence that seems to tell the plant it's the
right season for flowering. Sometimes, too, plants that aren't "doing well"
will bloom out of season -- apparently the urge to leave your genes behind
before departing for the compost pile can be quite strong. And then
sometimes, they just follow the first rule of experimental biology:
"under the most carefully controlled conditions, biological material
does what it d**
* well pleases." <g>
Chances are the fruits set now won't make it. If you think the plant
may be struggling a bit, you might want to de-fruit it now, in hopes
it'll do better next spring.
