Does it blossom all year? If not when does it blossom?

It doesn't blossom all year. These photos were taken in August - the plant was in bloom between July and October (at least). It would depend on what part of Ecuador you see the plant - and what climate zone it's in.

I have one in y back yard. they are considered junk trees here because they drop seed pods everywhere and grow easily and can take over. I love mine though we do call it a Mimosa tree here in Central Texas

5. They are also known as the sleeping tree Because if you grind up the seeds which grow in the pods - and smoke it - you'll drop off into comfortable sleep. WARNING: Do Not Drive Vehicles, Operate Machinery or Perform Surgery after smoking a "Pinkie".

Interesting that you say the "pink silk tree is known (incorrectly) as the mimosa tree." When I enter the Latin name of the tree in a search, I get many links all of which say it is the same....

The name mimosa is "incorrect" in the sense that it no longer belongs to the mimosa genus. As a common name it is fine, but the genus mimosa contains 400 species of herbs and shrubs. So the term is ambiguous. The names "pink silk tree" and "Persian silk tree" more accurately describe the tree. Albizia julibrissin belongs to the Albizia genus.
