An unknown herb in flower in the front lawn - haven't been able to identify it yet. Ricoh WG-6;
Well, the "short day" stuff means that the plants have to have at least 12 hours of complete darkness about two months before you want them to bloom. Commercial poinsettia growers have control over the amount of light the plants get, so they can force the plants to bloom for Christmas.
Yah, it's pretty subtropical here most of the time, some winters it never gets cool enough to even close the windows. But some winters, we do get a few chilly nights, temperatures down into the 40sF. This Friday is going to be one of those nights, forecast (I am not making this up) is for "falling temperatures and falling iguanas..." This neighborhood is right on the thermocline dividing "coastal" and "inland" temperatures. Depending on the wind direction, we can be on the colder or warmer side of the air mass. Actually I don't think "wild" poinsettias would be much troubled by that, but the fancy hybrid ones are less tolerant of cooler weather.
My apology, I re-read your post about the snowflake and realized -- after I posted my note -- that they do grow in your area. Sorry I can't help with your purple-flowered herb, doesn't look familiar to me at all.
Best wishes for a safe and joyful holiday, to you and all!
