Overview

With their arching, strappy, sword-shaped leaves, phormiums make a dramatic statement in the garden. Originating from New Zealand, where their fibre has traditionally been used in the same way as hemp or sisal, they are versatile evergreen plants that tolerate a range of conditions and look at home in a variety of different planting schemes. They have become increasingly popular in recent years, with more and more colourful varieties being introduced. Platt's Black is a wonderful introduction with sword-like, deep purple-black leaves. It makes a stunning centrepiece in a container, or an architectural specimen plant in the border, providing a fabulous contrast for silvers, pinks, blues and whites. In hot summers, a spike of tubular, red flowers will shoot up from the centre, followed by sturdy seed-heads.

How your order will arrive

Pots and Packaging
Larger pots (2L and above) are wrapped in waxed paper and then attached to a cardboard base so they stay stable in the box. The waxed paper prevents the compost from spilling out and gives the base some added protection from damp compost. For large numbers of plants, pallets may be used for shipping.

Preparation
The nursery will ensure the plant is moist while it's waiting to be picked up. Our quality control team waters the plant before packing them where necessary to make sure that the plant is suitably watered for transport. Plants with long delicate stems are secured with canes to prevent damage.

Plant on Arrival
Typically plants are delivered ready to plant and will take some time to settle, grow and look more like the product image above.
