There are some plants I grow to use as fillers, both in the garden and in cut arrangements. The rice flower shrub (ozothamnus) is one of those plants. It does well in both the sun and partial shade, although it tends to get a bit scraggly in shady areas and needs to be cut back to maintain a full look.
I have grown it for years and I like the way it looks light and airy in the garden beds when mixed with other plants.
The pink one has a tendency to fade in too much sun. It holds it's flowers for a long time and blooms almost all spring and summer in our area.
It also lasts a long time when cut and dries nicely too. The books say it has a pleasant fragrance although I must admit I've never noticed. Now I know someone is going to ask if this is the plant that rice comes from and the answer is no!
