Gardeners' Notes:

I love this multiple rebloomer. It blooms really early in the year here in my SoCal garden, sometimes as early as mid January. It is usually the first to bloom out of my irises and then again off and on into spring. Sometimes I also get a fall bloom out of them. It is very vigorous and multiple quickly. The color varies depending on the bloom time. When it blooms in the coolest times of the year, the color of the standards and the falls is slightly more golden than yellow and the hafts have darker amber colored veining near the beard. When it blooms later in spring, the color of the hafts is more yellow. I am in zone 10 so we don't get much frost to kill the reblooms.
