On my walk up my street this afternoon, every other verge had agapanthus, Agapanthus praecox, growing healthily. Definitely the predominant species round these parts.
Why it's a pest plant
It seeds prolifically, spreads seeds effectively which germinate densely. Fragments of the roots easily regrow. Plants live a long time and can handle a wide range of conditions and soil types.
Wherever it grows, it forms solid clumps. I've seen layers and layers grow on top of each other. It bullies all other plants out and takes over.

First day beating the feet during the rahui to save lives and eliminate Covid-19.
I explored part of Sinclair Park, discovering natives and exotic weeds mixed together. And a lovely wildness in the margins.

Life in the margins
A very large house with a small garden area, embedded on a densely housed hill in CBD.
The first job was to see what was involved in refreshing the garden area. We took photos of the various areas, cleared the weeds, pruned the very old rose right back and created a large compost pile.
