Introduction

Black Adder is a fantastic, deep burgundy/black colored Phormium. It is easy to grow and tolerates most locations without affecting growth or ornamental appeal.

Black Adder is ideal for containers and borders where a striking feature plant is required to set off lighter colored plants or ornamental containers.  As it matures, it forms an elegant semi-upright mound.  The glossy dark foliage becomes pendulous at the tips.

We love the bright orange-red flowers which cover the entire plant, and the way it keeps on blooming from late spring all the way through until autumn - Gardening Australia
