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.

These Flower Carpet roses are hearty and beautiful. At eight inches tall and planted 20 inches apart, I can see the promise of a 20 foot border along my home. :) Keep up the good work. - K.R., Michigan, USA
