GARDENING COLUMN SEPTEMBER 2019
With no rain of late and very little forecast our gardens maybe struggling to survive, though there is one plant that can thrive in these harsh dry conditions worth looking at.
Proteas are native plants to southern Africa and belong to the same family of plants as our Australian natives Banksia, Grevillea and Telopea species. This family is known as Proteaceae does also include another genera Leucadendron and
Leucospernum. This very large family of plants are from the ancient super continent of Gondwana era. As one of the very first groups of flowering plants able to adapt, spread seed, and diversify throughout the ancient continent. The Proteaceae family is one of the most dominant plant families growing in the southern hemisphere. Proteas can fit into Australian native gardens quite easily and will be well suited to Australian native landscapes. Whether it be a garden theme of secluded quiet courtyards, open entertaining areas, to large open garden beds. They give you year-
round colour and exceptional long-lasting cut flower displays, brought into the home decorative floral displays.
Protea Cynaroides Little Prince flowering protea have flowers of white with red fur like petals. Grows only to 1 metre, ideal for smaller sunny spots or can suit pot culture. Remember to use a specialty native potting mix to pots as regular potting mixes have too much nutrients especially phosphorous, for these plants.
Leucospernum glabra x tottum known as Carnival red. A very noteworthy addition to any contemporary style garden. Grows to 1.5metres high and shrub like 1.5metres wide. This flower has got to be seen believe me. Also known as pin cushions. Leucospernums have bright coloured pin cushion flower heads that demand attention.
Leucodendrons are unique as they offer outstanding colours that seasonally change throughout the year. Best times to enjoy these guys are in Autumn and Springtime when their dazzling colours put out a great foliage display. Once again suited to Australian native gardens and growing conditions similar to Australian landscapes. Leucadendron laureoleum x salignum Jolly Joker has variegated blaze of colour that also produces a long cut flower. Grows to 2 metres and is very successful in larger gardens, worth considering.
Proteas prefer a sandy loam or friable soil. If you have heavy clay soils it is necessary to first mound up the soil; to improve it add in compost and gypsum to break up clay. Allow to sit for a week to start reaction from gypsum prior to planting out. Proteas grow in fairly acidic soils as this reflects the conditions where they originate from South Africa and Australia. Proteas thrive best in full all-day sun some species can also be grown in semi shaded areas though check varieties available. The more sun your Protea receives the more it will flower for you. As to pruning this gives you a chance to shape your plant. Keeping it compact and looking great. Young plants need to be tip pruned in spring and late summer. Older plants prune as soon as flowers have finished, remember though leave up to 10cm of cut flower stem
with some remaining leaf below to support new flower sites the following year. All proteas are very low feeding plants, if required to boost growth at early stages a slow release for native is adequate. Most Proteas are frost tolerant to -2 c though in a year or so will have adapted to colder climates. Some varieties can even stand up to -6 c consult your nursery person to find the right type for your situation. I have many of these varieties ready for sale. Pay us a visit to view the display and the choice is yours.
Keep growing
