how do Gazanias re-seed
I wish to save seeds to plant more Gazanias next spring. How do these plants re-seed?
In the far south they reseed themselves. They probably won't survive the winter in zone 8. You'll get better results for next year by starting cuttings. This article has more information: https://www.gardeningknowhow.com/ornamental/flowers/gazania/gazania-treasure-flowers.htm
