Wombat Berry produces plenty of showy orange berries.
The berries also attract fruit-eating birds, and the tuberous roots attract wombats and other native root-eating mammals. Wombat berry is moderately fast growing but not excessively vigorous which is handy as it's unlikely to smother other plants.
Eustrephus latifolius is an adaptable plant that thrives in sun or partial shade. It can tolerate extended periods of dryness once established. Wombat berry will grow on most soil types and even tolerates light frost.
As the tubers are spread out around the base just scratching around you can dig a couple up without hurting the mother plant, as long as you work out and away from the central stems.
When cooked they can be a bit tough, and taste just like a normal spud or yam, but raw are awesome, like a juicy apple in texture, and mildly sweet.
