What's Blooming Now - Cassia corymbosa April 22, 2012

This little tree or large shrub is a larval food source for the Sulphur butterflies.  I have always considered Cassias to be late summer bloomers, but I guess I was wrong.  This particular variety seems to be fairly cold hardy.  I had another variety, and it was really large (never wrote down the name of it).  It was growing in the yard of my Houston home.  Three winters ago, when the weather stayed below freezing for several days, it died.  This past winter was not as severe, but it definitely gets colder in Brenham than Houston.  Anyway, so far so good.
