Q.Will Purple Fountain Grass Disrupt Garden Edging If Planted Too Close?

Zone Melbourne 3000 | Anonymous added on May 13, 2021 | Answered

I have a narrow (40-50cm) garden bed against a wall that I’d like to use normal (not dwarf) purple fountain grass in for its height, but the border of the bed is just plastic grass barrier lined with some bricks. If I put the full size purple fountain grass in (which is meant to get to about 1m diameter), do you think it might eventually push the edging around and disrupt it? There is a path of paver stones 10cm from the edge that I don’t want to mess with. Thanks for any opinions!

You certainly could have a problem with this. These grasses can become invasive. It's low-maintenance and would look attractive there but could cause problems later. You may want to consider an alternative.
