Mine has dropped leaves although I am in zone 10. I have the grass growing right up to the tree and it is watered regularly. I wonder why the leaves are dropping. Am I supposed to feed this tree? Does it drop leaves when it gets cold and then come back in the spring?

I am in Zone 9b, Australia. Having discovered this plant struggling, squished between a thicket of various privet trees - I would say it appears to be quite hardy - has a lovely soft leaf and bright yellow pea flowers. May have the potential to become a weed in some areas, as they seem to readily self seed. I had known this as the Scrambled Egg Tree, however I think I like the name 'Sunshine Tree' better as it really is pretty.

I've grown Senna (Cassia) surattensis in California, in coastal Los Angeles, and in a residential landscape job 50 miles inland, in Rancho Cucamonga, where it performs beautifully despite occasional light frost. It may very well take a bit more frost, and/or be a dieback shrub in zones 8b-9a. Of course very beautiful in Hawai'i where it's called Kolomona. Senna surattensis has a very nice, "fluffy" appearance and stays relatively small (about 10 feet in California).

The tree labeled as this in the Huntington Botanical Gardens is quite ornamental and has wonderful flowers... but they look different from all those I have scanned on other sites. Great low-growing but spreading tree. Hardy in zone 9 at least- not sure its limits, though
