Mine are up too but I am in zone 7 and although it's unlikely, it is possible that we may not see any real cold for the remaining part of the winter. Lows have been in the 20's and 30's with nice sunny days. I pushed my winter sowed containers close to my house on the porch so they only get very early sun - even in Jan the New Mexico sun would fry those little guys in a closed container.

Crazy weather....I saw bits of green popping up in the yard.

I'm seeing lots of weeds :(
Gonna have to hire a neighborhood kid to help me get the front bed ready for new plants this spring. It's been a very mild winter so far, it's very odd. Maybe Spring will be early and that would be a very good thing.

Some of our Daffs have been up since Dec. (which is normal)
I have one that started blooming this week. (not normal)
