Also known as New Zealand Flax, Phormium 'Black Adder' is a robust, fully hardy evergreen which forms a dense clump of sword-like leaves -  a really great plant for adding a bit of a statement to your garden. Stunning in a border and stylish in a container, this recently introduced phormium plant has particularly attractive, deep purple, almost black, lustrous foliage, and is a compact form - meaning that it won't overshadow everything in your garden. Phormiums prefer a hot dry site (although will tolerate partial shade) and make a great candidate for a Mediterranean garden or a gravel garden where their upright leaves make a great foil for many other coloured plants. Easy to grow, phormium 'Black Adder' is a compact form, slightly more upright than the popular 'Platts Black' and needs virtually no maintenance - it may even reward you with spikes of red flowers in late summer. Ultimately growing to around 1.2m, we supply well-established plant, 0.8-1m tall in a 5L pot.
