Aloha,
If I hadn't gotten out into the woods this weekend I'd be hating you right now.
The palm tree in the first picture, are those fruits edible? There's a lot of palm trees like that in my neighborhood and they produce the same sort of clumps of berry-things. I haven't been able to find out if I can eat them.
The second picture looks like it might be a loquat tree, which produces edible fruit. If the fruits turn yellow-orange and grow to the size of grapes it probably is a loquat.
The fifth picture (fuzzy pink puffballs) is a mimosa tree. They are invasive here in the Houston area.
Thanks for the pictures.
