Yes, and also butterflies and hummingbirds.
The first tree I have that bees flock to in early spring is an elm—possibly an American elm, but I'm not certain. Next is a cottonwood (Populus deltoides). I know when these trees are blooming because of the buzzing. I used to have a mimosa tree (Albizia julibrissin) and bees liked it too. Here is a link to other trees important to bees: https://www.thoughtco.com/best-north-american-trees-for-bees-1968106
Hi Leo, For sure it is!
No, Magnolias, Jasmine, mint, Berginot, lemon balm, orange lemon lime trees.
Flowers are better and not mess of leaves and dead flowers. Magnolias don't shed a lot of leaves but those seed pods can tear up a mower.
I"m not sure about bee forage, but around here, Mimosa trees tend to want to take over. Just our experience.
