It could be Pinus canariensis or it could be Pinus maximartinezii? Any more backgeound info like who's growing them. There are Pinus canariensis growing that you have identified already and this specimen here is different than the canariensis you've already identified?

Seem to recall an annual/perennial that looks like that.

@Jay 6a Chicago There are tons of Canary pine trees that randomly sprout up all over. The hidden ones that sprout inside a bush become very tall and visible. There are also very large Stone pine here and there but I have never seen them sprout. And for whos growing them, I think they must have been planted 40-50 years ago when they were developing the land along with a bunch of other trees. This is Westlake Village CA.

I didn't know that Canary Pine was an invasive species. I'm no expert on pines. I sugested P. maximartinezii because of it's deep blue/glaucus color, and it's threatened in the wild, in northern Mexico.

Could Pinus halepensis also be a candidate?
