Also known as New Zealand Flax, Phormium ‘Black Adder’ is a robust, fully hardy evergreen which forms a dense clump of sword-like leaves –Â 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, 60-80cm tall in a 5L pot.
Care Information
- Plants dislike cold, damp soil, so are best planted in full sun in well-drained soil, such as in a gravel or Mediterranean-style garden.
- Avoid planting in exposed places as wind and cold will cause die-back on the leaves and stems. If damage does occur after a harsh winter (colder than -10?C), plants can be trimmed to remove dead growth, otherwise they need no pruning.
- In colder areas they need to be given some mulch or other protection around the base of the plant in winter.
- Other than that, really easy!
