Haloragis erecta 'Wellington Bronze'
A vigorous self seeder from the North Island of New Zealand, Haloragis is a plant you either love or hate on sight.
It has colonised the poor soil underneath the nursery benches where nothing else will grow and it manages to pop up even on our appalling, pottery quality, heavy clay.
It's easy to control as the seedlings have the same lovely bronze foliage as mature plants and although a bit rampant it doesn't seem malevolent. So all in all we like it.
Seeds from the plant were taken to England as early as 1778 and grown at Kew Gardens but it clearly didn't catch on. This seems a shame as the lovely bronze foliage is the perfect foil for the showier specimens in the border. The flowers are inconspicuous being the same bronze, burgundy colour as the stems.
Planted in shade the bronze colour is not so intense and reverts to a dark, greeny-bronze.
Not a plant for everyone and it does come with caveats but could fill a gap where nothing else will thrive.
