Gazanias (Gazania spp.) are enjoyed for their brilliant, daisylike flowers that appear year-round under ideal conditions and are available in shades of yellow, orange and red. These plants, which offer excellent heat and drought tolerance, grow as perennials in U.S. Department of Agriculture plant hardiness zones 8 through 10, although they are cultivated as annuals across a much broader range. Gazanias are frequently hybrids, and plants grown from seed may not necessarily feature the same desirable characteristics as the parent plants, but collecting gazania seeds and sowing them in subsequent years is still a fun activity and can yield interesting, attractive flowers.
1 Cut seed heads off of the gazania plant when the old flower heads are brown but before the small gazania achenes, or fruits, begin to fall off.
2 Spread collected gazania flower heads out over a fine mesh screen and keep the screen in a cool, dry area with good air circulation for at least a few weeks to allow the achenes to dry completely.
3 Rub the flower heads over the fine screen to release the gazania seeds from the achenes and separate the seeds out from the achenes, fluff and other debris. Place a piece of paper under the screen as you are rubbing the flower heads to catch the seeds and make it easier to transfer the seeds into a container.
4 Place the gazania seeds in an airtight container and label the container with the collection date, information about the parent plant and any other pertinent data. Store the gazania seeds in a cool, dry place with a temperature maintained between 34 and 41 degrees Fahrenheit.
Items you will need
- Fine mesh screen
- Piece of paper
- Airtight container
- Letting the gazania flowers go to seed will reduce blooming, so consider waiting until the end of the growing season in temperate climates to let the plants produce seed for you to collect. Otherwise, cut off spent flowers regularly to encourage constant blooming.
