Green thumb: Kangaroo paws for effect
KANGAROO paw (anigozanthos) are one of the most internationally recognised Australian flowers.
Their curiously shaped paw-like blooms come in a range of colours and heights, and provide a wonderful display in the garden and in pots. They make a great cut flower.
Kangaroo paw have a clumping growth habit with strappy leaves. The flowers have a felt-like appearance and are carried on stems above the foliage. A mature plant can produce more than 30 flower stems in a season.
Colours range from white through pink, red, orange, yellow, mauve and even green. Much breeding work has been done over the past 30 years or so, and there are now dozens, possibly hundreds, of varieties available to gardeners.
Generally speaking, the taller varieties, and those with green leaves (rather than the bluey or grey foliage) are the stronger growers. They will last for many years in the garden.
The dwarf forms have a shorter life span, flowering almost year-round for a few years. They are best treated as an annual or short-lived perennial. Because they flower so profusely, they are fabulous in pots.
Caring for your kangaroo paw is easy. First, choose a very sunny, well-drained position. When planting, ensure the crown of the plant is no deeper than it was in the pot, as planting too deep will encourage disease.
Once established, they are quite drought tolerant, but they will require some water to flourish. They will appreciate an application of fertiliser a couple of times a year.
Water stress at flowering time will cause the flower stems to bend or fail altogether. Try to keep the foliage and the crown of the plant dry when you water.
Remove spent flower stems at the base, removing the entire flowering shoot, leaves and all. If you are growing the tall varieties, you can prune the whole plant back to ground level after flowering to promote a great flush of flowers the following spring.
In their natural habitat, kangaroo paw have a deep root system, enabling them to survive in dry periods. So if you are growing your paws in pots, it's best to choose a deep pot to give that root system room to develop and make them less reliant on frequent watering.
Leaf blackening will sometimes occur when leaf or flower stem tissue dies. There are many causes, including frost, excessive humidity, too much or too little water, pesticide damage, and disease.
Fungal conditions will also cause black or brown marks on the foliage. Obviously, try to identify what is causing the problem, and correct it. But whatever the cause, removing the affected foliage will help to slow the spread of the disease.
The spectacular flowers more than compensate for the occasional challenges encountered when growing kangaroo paws. Don't be deterred by the fact that they may not last forever. Think of it as an opportunity to try a new variety next time.
