Dianella tasmanica
« on: July 28, 2022, 05:04:33 PM »
Although I am very fond of this plant for its numerous bright blue berries at this time of the year; it is a bit of a thug once it starts spreading by its far reaching runners. They come up some way from the main clump; often amongst something else. In my case usually the larger irises. I aim to move it this autumn but wonder what its behaviour is going to be on a slope of ~1 in 4. Will it go all ways, up, down and sideways of will the slope confuse it? Will it have a preference for any particular direction on a slope? The slope faces west. Heavy stoney chalky soil.

I confine mine in a cylinder of 1" x8' chicken wire.  The wire is soon completely covered, so it is not unsightly.

To let folk see the plant in question .... from elsewhere in the forum, by John W in Canada

 -worth noting perhaps that some people regard this as a weed  ??? :-[
