Plant Profile - Landscape Gazanias

Gazania are low growing perennials from South Africa and are widely grown in Australia due to their excellent drought tolerance and ability to cope in coastal environments and survive in poor soils.

Over the years Gazania’s have been a favourite with gardeners living in coastal areas due to their bright daisy like flowers and ability to survive in salt laden winds. However Gazania species like linearis and rigens in these areas are considered very invasive and will produce large amounts of wind blown seed from nearby gardens and will spread rapidly along roadsides and coastal dunes.

Gazania rigens or Coastal Gazania has become naturalised on coastal dunes and along roadsides in many areas across the country. This has given Gazania a bad name throughout the years and for good reason, so please be aware of this issue and avoid planting seed grown Gazania’s in these areas and use some of the new sterile forms.

There are really two types of Gazanias the clumping and the trailing type. The clumping types are more often used in garden situations where they are very easy to grow and provide beautiful flower colours throughout the warmer months. Gazania’s have come and gone over many years but recent breeding has provided big bold flower colours in the clumping range of Gazania’s and they are becoming popular again.

The trailing type of Gazania such as the Silver Leaf Gazania or Gazania tomentosa hybrid is the most popular landscape Gazania. Extensive breeding work has been conducted by Nuflora International and the University of Sydney Plant Breeding Institute to develop new and improved Gazania cultivars for the landscape market. Some new cultivars of Gazania tomentosa hybrid have now been developed and the beauty of these cultivars is that they are completely sterile and will not produce seed that can spread and germinate into unwanted areas.

Double Gold is the name of a new release landscape Gazania tomentosa hybrid bred by Nuflora International. Not only does it have the benefit of being completely sterile but Double Gold has a great spreading ground cover habit with clean growing foliage and beautiful double yellow flowers. It has twice the flowers next to most other Gazania’s.

Double Gold is a tough plant for almost any situation. It is perfect for soil stabilization on embankments and works well in harsh conditions such as roadsides, front verges and roundabouts. It is frost tolerant and requires little watering and care once established. Double Gold is fast establishing and excellent at outcompeting weeds. Compared to the common Gazania tomentosa hybrid it has a more compact growth habit, better flowers, it is sterile and does not tend to die out and leave a gap when mass planted.

Other Silver Leaf Gazania types that have come out of this breeding program have been more garden type selections. Gazania Tiny Tom is a compact, tidy ground cover with a neat habit and flowers for most of the year. It is attractive in terraces and embankments and perfect for rockeries, growing 20cm high x 1m wide. Tiny Tom is self incompatible meaning that it is only sterile if it is not planted around other Gazania. If it is it will pollinate and produce seed.

Gazania Sahara also bred by Nuflora International is a fast growing, non-invasive Gazania which produces large, double, bright yellow flowers for most of the year. Sahara is a hardy, low maintenance plant and will thrive in a range of conditions.

Keep Gazania’s in mind for those difficult sites with problem soils or dry conditions. They are very resilient plants and now with new sterile cultivars in the market you can be safe in knowing they are not going to spread around into unwanted areas from windblown seed.

Please note: I have referred to Gazania tomentosa as a hybrid, even though we all know the Silver Leaf Gazania as Gazania tomentosa it is not actually officially recognised as Gazania tomentosa by any relevant government authority. It is only recognised as Gazania hybrid. I think this is due mainly because Gazania’s hybridize so easily, it is nearly impossible to establish the background of the plant and it makes identification very difficult.
