Spiky Palm Trees of Death

More art homework. Yes, I painted over a photo of my neighbor's yard, but I was the one who took it and it took way too much time and too many layers.
This isn't the version I'm turning in, but the layers I hid were part of it and a tribute to my late ball python Murgatroid. I decided to take them out for uploading it because they didn't look so great, seeing as I couldn't image search for reference snakes without starting to cry. I miss him a lot. He was the best snake in the world. I hope he's getting lots of love up in snake heaven.

...Anyway, does anyone know what those trees are? I can provide the photo, but they look like palm trees but super spiky. Google has so far been unhelpful.
