Lime tree blooming AGAIN!

Winter in the Bay Area is so wonderful because instead of everything dying, so many plants bloom! The grass gets green and the landscape looks happy and healthy instead of the starkness of colder climes.

 

Are lime trees supposed to bloom in the winter? I thought they liked it HOT! When living in Phoenix AZ, I was told that the heat makes citrus sweet. Gosh I miss my 7 foot tall lime tree there -- it was so prolific and such a beautiful plant. When it bloomed, you can smell it all over the neighborhood. Maybe neighbors have citrus too that that's why the scent waffed through the neighborhood?

 

My Bearss Lime (yeah, its label really has 2 s's) is probably more than 10 years old, counting time with me and at the nursery, but it's still, um, rangy. It doesn't have the dense branches and leaves of my lime tree in Phoenix. Maybe it's a different kind?

 

The daphne has blossoms, even though all the lower leaves have fallen off, and an occasional leaf still turns yellow and falls off. Does that happen when plants are root-bound so cannot get enough nutrition/water to support the lower leaves? Do daphnes have big roots? They don't like their roots disturbed. maybe I can propagate it instead?
