Plant of the Week
Flowering senna is a beautiful plant in the late summer and fall when it bursts with blooms. Depending on the growing conditions, it forms a small tree of about five to 10 feet high. Especially it's noted for it airy appearance and brilliant yellow flowers.
It's quite hardy in our area. Sometimes in colder climates it can die down to the ground, but we find that here it does really well coming back for us each year. And it is a late season bloomer so it gives you some late season color in the garden. You can let it form a giant mounded bush or you can trim it up, forming sort of a mini tree by removing the branches down around the lower trunk.
It's also a larval food source for the Sulphur butterfly.
