Ice plant! If there were EVER a bit of flora that said “urban SoCal”, screw the palm trees; ice plant has it in the bag.
THAT stuff is E-V’RY-WHERE!
We had it down the back slope at the house I grew up in, over in Anaheim Hills. It’s all along the freeways, and up and down I-5 from Simi Valley south.
SoCal and ice plant are geographically synonymous.
Ice plant is the bomb. Saved my place in the mid 1980’s Murphy Canyon fire. Stuff is almost impervious to fire.
