Description

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, 60-80cm tall in a 5L pot.

Top Tips
Grow in a silver-coloured container for the ultimate in contemporary planting.
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!
Delivery Information

Please allow us 3-5 working days to dispatch your order. Pre-ordered items will be sent as soon as possible after the date quoted and we'll generally ship your entire order with your pre-ordered items. When your order is dispatched, we'll send you another email with details of how to track it.

Most orders are sent on a fully-tracked courier service with Yodel. To avoid perishable items being stuck at depots and deteriorating, no signature is required, and our courier is asked to leave your order in a safe place on your property.

We'll send a tracking link when we dispatch your order, so you know when its due to arrive. Please note, once delivered we cannot be held responsible for loss or theft from your property. If you have any specific delivery instructions, please let us know - there's an option to enter a short message for the courier at the checkout.

Smaller, lighter, single-item orders may be sent through the post with Royal Mail - in which case no tracking is available.

Our experienced nursery team will always send your plants nursery fresh in the perfect condition to thrive when you plant them, so although most plants are very tough and will not be affected by all but the most extreme frosts or heatwaves, we avoid dispatching the most perishable plants if extreme weather is forecast, or over Bank Holiday weekends.

Please note, we cannot guarantee delivery on a certain day or time. Delivery to outlying postcode areas may take 1-2 days longer, dependent on your location.
