It's been growing for several years now, and is about six feet tall. (My
oval leaf Cassia, Cassia
, that I planted at the same time is well over ten
feet tall now.)
I think this plant is Privet Cassia, Senna ligustrina. There are so many
kinds of Cassia
that it's hard to tell. Regardless, my
lay eggs on it, so I like it.
