The Persian Silk tree (Albizia julibrissin) is a small tree native to a broad region that extends from Iran all the way to Japan. This trees name comes from its delicate and colorful flowers that look like little puff balls.
I´m not sure how large this tree species can grow but all the trees that I have seen (it is a very commonly planted tree in Spain) have been on the small side not more than 10-12 feet tall. This makes it an ideal tree for gardens as an ornamental tree.
The leaves of the Persian Silk tree (sometimes just called "silktree") are bipinnately compound and have a close resemblance to many acacias although they are not related at all. At night these leaves relax and fold up as if they were sleeping only to spread back out when the sunlight returns.
The seed pods of this tree species are so thin that they are translucent allowing one to make out the silhouette of the seeds on the inside. They are a tan color and are about 3-4 inches in length. They are normally flat but on occasion you can find ones that are twisted in a spiral fassion.
