Gardeners' Notes:

A local native plant nursery/landscaper came up with a plant of this species for me to try early this year. It grew well in an irrigated, sandy, sunny site and has produced several bright yellow daisies from July to September, so far. The stems are rather floppy this year. From what I read, I expect upright stalks next year. I am impressed enough that I will be looking for more plants next year.
