Anigozanthos ‘Rampaging Roy Slaven’ – Bush Gems Landscaper Series

Rampaging Roy Slaven – A great plant for a great cause!

Angus worked closely with his good friend John Doyle and Ramm Botanicals on this project to create a plant in honour of the iconic Australian character created by John, “Rampaging Roy Slaven”.

From the start the project was designed to raise funds for the wonderful charity Aspect of which John Doyle is patron. ASPECT primarily provides early intervention services for autistic children to help them adapt to life in a society that does not always appreciate the way that autism affects their lives. Anigozanthos ‘Rampaging Roy Slaven’ is the result of a unique collaboration! Ten cents from the sale of each ‘Rampaging Roy’ plant will go to support the wonderful work Aspect do for those with autism and their families and carers. To date this plant has raised over $50,000 for Aspect!

This fantastic mid-sized Kangaroo paw will establish easily in the garden and perform for many years with minimal attention, bearing masses of brilliant orange red flowers all year round. ‘Rampaging Roy’ has been selected for resistance to disease, and will thrive and flower prolifically for years with minimal maintenance.

Designed for landscape use and permanent plantings as part of the ‘Bush Gems Landscapers’ range, ‘Rampaging Roy’ also has excellent cut flower potential, making this one of the most reliable and versatile Kangaroo paws available.


Along with ‘Bush Gold’, ‘Rampaging Roy’ is one of the toughest of the medium-sized kangaroo paws, and unlike many of the other smaller paws this plant is both long-lived and low maintenance.

This variety of Kangaroo Paw has dark green iris-like foliage growing in a cluster up to 1m wide and masses of iridescent orange to red flowers on deep red gold stems. Flowers prolifically right through the year (in frost free climates) atop a well branched flower stem between 1 and 1.5m high.


Attracts Wildlife

Kangaroo paws and this variety in particular are excellent for attracting birds, their abundant nectar provides a feast for many different native birds including honeyeaters, wattle-birds and spinebills. The luminous orange flowers also attract butterflies and bees.
•Perfect Landscape Plant
Bred for toughness, longevity and beauty ‘Rampaging Roy’ represents all the best qualities of Australian native plants and has been created to fill the demand for a reliable Kangaroo Paw for permanent plantings and landscaping.
•Great Cut Flower – Spectacular Native Colour
The iconic Kangaroo paw has long been a very popular native cut flower and

‘Rampaging Roy’ is a great variety for this purpose, bearing vibrant deep orange red flowers year round on a hardy low maintenance plant.


Landscape and Garden

A tough, low maintenance Kangaroo Paw that will perform reliably for many years, ‘Rampaging Roy’ is an exceptional landscape plant. ‘Rampaging Roy’ is also great for permanent home garden plantings and large pots or containers.
•The lush evergreen foliage and stunning flowers make it a spectacular feature plant, it is also fantastic for mass plantings where the floral display will really make an impact.
•Makes a great backdrop planting or mixed planting with other varieties of Kangaroo Paw and popular native grasses to add colour and depth to Native garden designs.
Cut Flower Production

The hardiness and long flowering period which make ‘Rampaging Roy’ a great plant for landscapers and gardeners, also make this an ideal plant for cut flower growers.
•Their long stems, well branched stems and tough flowers mean they are a beautiful and long-lived cut flower, and have made them a favourite with florists.

•The year round flowering of this variety is a real bonus for growers with the potential for successional crops from the same plants in one year, and ‘Rampaging Roy Slaven’ is suitable for greenhouse cultivation and large scale commercial production.

•Full sun to partial shade, the flower colour can vary with different light levels
•Drought tolerant – Whilst this variety will survive a prolonged dry spell it should be added that it may not flower well if it dries out while the flower stems are forming.
•Frost tolerant (Light)
•Soil – Good drainage is necessary. Add a small amount of organic matter to the soil when planting and mulch well afterwards to encourage strong healthy growth.
•Low maintenance

Pruning is important to keep Kangaroo paws healthy and attractive year round, particularly with the long flowering mid-sized varieties including ‘Rampaging Roy’.

All old foliage and flowers should be cut right back to ground level. This can be done with secateurs or even a lawnmower for large plants!
Hint from Angus– Cutting back to ground level may seem extreme but it actually encourages the growth of healthy new shoots which will bear the next year’s flowers. After all, in the wild Kangaroo paws can survive and flourish through extreme conditions like bushfires and hungry kangaroos and wallabies!

•For best results prune 2-3 times per year during their growing season in Spring and Summer by removing old flower heads as they finish. You should also remove the attached leaves as each fan of leaves supports just one flower stem and will begin to die back after the flowers have completely finished. This will encourage more flowers and keep the plant looking healthy and attractive.

•Water the plant well throughout the growing season to encourage extended flowering, particularly as the flower buds are forming. Though they are drought tolerant they respond best if watered well during their growing season beginning in early Spring. This will help to increase the longevity of the blooms. Water more frequently when establishing and apply a good layer of mulch after planting.

•Fertilize after pruning back with a generous handful of either a general purpose or Native fertilizer. ‘Rampaging Roy’ is not overly sensitive to Phosphorus. Feed again in Spring during their growing season for spectacular displays of flowers that year.

•Older plants will respond well to being lifted and divided every one to three years, this will reinvigorate the plant and is a great way to easily multiply your Kangaroo paw into several healthy new plants.
Hint from Angus-

If using for cut flowers try taking off just the top half of the flower stem (cut just above the lower flower buds on the stem as soon as the first flower has opened) and using this indoors as a cut flower.

This encourages the dormant lower flower buds on the bottom half of the flower stem to grow, which will extend the flowering period and give you more flowers from each stem.
