Landscaping with Vetiver

I do like to know how our children are getting on in life.
Here's 20 of them in their new home: the makings of a hedge on a Brisbane garden verge.
The Vetiver will not only soften the fence line, but the plants will also act as a wick drawing up moisture for the herbs also planted in the bed.
As a self-sustaining exercise, any time the Vetiver is cut, the leaves are simply dropped to mulch the bed.
Below is another application for Vetiver. This time on a rising house block with runoff scaring.
 The owner dug a few swales and reinforced the fall with Vetiver clumps.
