This flower stopped me in my tracks the first time I saw it growing in Phoenix, Arizona. It is one of those shish-ke-bab flowers - the blooms are spaced out on stalk of 3-4'. They're a light yellow and unusual in form.

This plant can withstand very hot summers (zn 9), but will need additional water. In milder summers it is somewhat drought tolerant.

The leaves are fairly large, triangular, almost olive in color, with a felt-like feel. They grow thickly, making a good weed barrier. They are not harmed by frost, so I guess in my 6b/7a area you could call it semi-evergreen. In the two years I've had it, it has spread about 6".

The only issue I've had since growing this plant is that it takes a good while to bloom - this will be my third year and I'm hoping this is it!
