The Swan River Daisy is a low-growing annual, with pretty purple and white flowers on delicate stems. It's foliage is serpentine, and light green. So why should you grow it? Well, it really is pretty in an unprepossessing way. And it makes a nice tuckaway plant for borders and container plantings.
They come up easily from seed and grow reasonably well in partial shade and better in light sun. Their growth habit is a lot like lobelia, and the two plants share a tendency to grow out from the root, leaving behind a mat of dry, undergrowth. You can cut them back, but in a shorter season, they don't tend to grow back well. Flowering is continual once they start blooming in midsummer.
