This looks like a Albizia or a Acacia. The leaves are exactly like the Albizia-Mimosa but the flowers are beautiful! Yellow pedal Flowers very similar to Cassia Fistula. I found this plant last year and saved the seeds and planted over the winter in Oklahoma (zone6). As for growth it started in spring and now in July it is flowering. It does close its leaves at night. But if you touch it the leaves will not close. Can anyone help?

I was told by my husband that this plant grows to a tree about 20-30ft tall. If it is true I will be replanting this in my back yard.
