Azalea ‘Encore’ Autumn Fire
The Encore range of Azalea represent a breakthrough in breeding and development of Rhododendron.
These plants are repeat flowering, more heat and drought tolerant, and show significant resistance to pest and disease. The range has many colours and sizes, with most showing compact growth around 1m tall.
These plants are suitable for container growing, or in gardens, and will repeat flower throughout Summer, Autumn and Spring.
Fertilise each season with a quality acidic fertiliser, suitable for Azalea, to ensure continued performance and prune well after flowering in Autumn. These plants can be grown in full sun to part shade and are a great way to get colour in a small space. With over 7 colours to choose from, there is an Encore Azalea to suit all styles
Hardenbergia ‘White Out’
Native to Australia, this fast growing, evergreen climber will be a hardy addition to any garden. Delicate sprays of pure white, pea-shaped flowers adorn the plant from mid winter through to mid spring above attractive lime green foliage. Flowers are borne in profusion from mid winter through to mid spring above attractive lime green foliage and stems.
‘White Out’ is easy to grow and will thrive in most conditions if the soil is well draining. Suitable in both ground and container gardening. Plants perform best in open full sun positions.
Fertilise with a controlled slow release fertiliser in spring and late summer. Regular pruning is recommended to maintain fresh vigorous growth, especially after flowering. The growth habit is shrub-like making ‘White Out’ ideal for use as a low spreading screen. It will quickly cover fences, trellises, archway and pergolas covering an area approx. 2.5m x 2.5m.
Protea – Little Prince
Protea are part of the Proteaceae family. Well known members of this family include Grevillea, Banksia and even Macadamia Nuts. Protea are a South African native, but along with their close relatives, Leucospermum and Leucodendron, these plants prosper in the same conditions as many of our native species. Protea are often grown for their cut flower properties, but also perform well as potted or garden specimens.
It is important to get the environment right for these plants to grow successfully. They require a very well-draining position, with no chance of water logging, or ‘wet feet’. They won’t tolerate heavy clay soils, but will perform well in a well-draining, native potting mix, if your garden isn’t suitable. They can be fertilised every 3-4 months using a slow release, native fertiliser, and should be trimmed after flowering in September/October. They are best grown in full sun and don’t like being smothered by other plants – so give them plenty of space. Water well to establish, but once they are settled, protea will tolerate extended periods of drought.
Little Prince is a more compact growing form, bred to produce the large flower types of the ‘king’ protea, but on a smaller growing plant. Little Prince will grow to 1m tall by approx. 1m wide.
Begonia have long been a favourite in many gardens, and with hundreds of different recognised cultivars, there really is a begonia to fit most situations. Diadema is a hybrid, upright cane type begonia, producing an abundance of pink flowers. This variety will flower from March through to July and enjoys a warm, well light area, but not in direct sun. It is not a large grower, only reaching approx. 60-80cm in size, so perfect for a container or for inground growing. Like all begonia, it doesn’t like to have wet feet, so ensure plenty of drainage. Fertilise well with a slow releasing fertiliser in Spring, Summer and Autumn and trim well back in Spring to encourage new growth and potential new blooms. Begonia will flower indoors as long as they are kept in a well lit area.
Plumeria Pudica- Everlasting Love
This variety of frangipani is fast becoming one of the most popular. It is almost evergreen in our climate, and produces an abundance of white flowers from late Spring through to the end of Autumn. It is a fast growing variety, reaching a total height of 3m if left untrimmed. It can be kept trimmed happily from 2m. It has a lovely upright growth habit and performs more like a shrub, than a traditional tree.
- Like all frangipani it prefers full sun and needs a well-draining soil.
- It is a perfect plant for containers or directly in to the garden.
- Prune well in Spring to encourage new growth.
- Feed in Spring and Summer with a flower promoting, slow release fertiliser.
- Unlike other frangipani it is resistant to the rust disease which can plague traditional forms
Sometimes referred to as the tulip of the tropics, Curcuma are an impressive flowering ornamental ginger. Aside from the edible crop of turmeric, most curcuma are grown as an ornamental, flowering garden plant.
Flowers range from red to pink to yellow and white. All varieties are deciduous so remember to allow for them to die back during winter – just remember where you plant them as they will flower up again the next season. Flowering in the warmer months from December through to March, these gingers are incredibly showy and can even be used as cut flower.
These plants do prefer part shade, as full sun tends to bleach the flowers and foliage. Fertilise well with a slow release fertiliser after flowering, before they begin to die down for winter. Once dormant, allow to remain dry until new shoots emerge.
They are very suitable to be kept in a pot or in the garden, and most varieties are well behaved – not developing a large root system or spreading out of control.
