Soft tangles of lacy foliage and drifts of periwinkle, rose, blue, and white blooms make this Australian wildflower a favorite in the cottage garden or landscape. It is grown most often as an annual but can be treated as a perennial in USDA zones 9-11. Plants grow to an average height of 12- 36 inches and to about 1-1.5 feet wide. Try this long-season bloomer in containers or planted in the ground.
