The Spanish Gorse is a rarely seen but highly attractive non invasive ground cover shrub ideal for sunny dry banks.
It grows to about 1metre tall by as much as 3metres wide and has spiky green stems without foliage for much of the year so is texturally interesting.
Come spring it erupts with a mass of little yellow pea flowers as one would expect.
I have never had it self seed in the 20 years I’ve grown it and it smothers weeds like you wouldn’t believe.
