Hosta 'Holar Black Swan'
A clump-forming, deciduous perennial to a height of around 38cm, with medium-sized, glossy green leaves with very wavy edges and prominent veins. The leaf stalks and flower stem are a striking red-black, which make this hosta even more eye catching when the pale purple flowers appear in summer
