How can I differentiate between Albizia (Mimosa, Silk Tree) and Delonix regia (Flamboyant) when the plant is young?
I live in Maui, where Albizia is an invasive species responsible for monocultures, loss of habitat, build and road damage, and even falling and killing people. I want to be aggressive about removing it from my property. It's also much easier to kill when it's young.
However, I also have a Delonix regia (Flamboyant) growing in my backyard which looks similar except for its flowers.
How can I differentiate between the two when they're young so I can kill the Albizia but not the Delonix regia?
Update: I've recently learned that there are two different species (genuses, actually!) called Albizia here in Maui: Albizia julibrissin and Falcataria moluccana. I also don't know how to differentiate these, but they're both invasive, so I want to weed out both. It seems Falcataria moluccana is more common.
