Plant Description

Phormium Platts Black is an architectural hardy tropical grown for the appeal of Phormium 'Platts Black' and green evergreen foliage. This New Zealand Flax is an excellent choice for borders, containers and patio pots, where it brings colour, texture and seasonal interest. It performs best in a sunny spot and rewards the right position with reliable garden performance.


Phormium Platts Black is low-maintenance once established and suits a wide range of garden styles, from traditional borders to more contemporary planting combinations. Reaching around 1.5m at maturity, it is best planted through the middle of a border, in pots and containers and as a specimen plant with a sunny spot. Its evergreen foliage ensures year-round presence in the garden. It is suitable for outdoor growing in most UK gardens. It performs best in sandy, loam or chalk soils that remain well drained.

Supplied in a 5L pot, this size offers a practical starting point for planting out, patio displays or growing on at home.

Planting & Aftercare

Choose a pot with drainage holes slightly larger than the nursery pot. Use well-draining potting mix. Place the plant at the same depth it was in the original pot. Water thoroughly after planting.
Water when the top 2-3cm of soil feels dry. In spring and summer, this is typically once a week. Reduce watering in autumn and winter. Always check the soil before watering to avoid overwatering.
Overwatering is the most common issue. Avoid placing in direct sunlight which can scorch leaves. Don't repot too frequently - most plants prefer to be slightly root-bound. Ensure good drainage to prevent root rot.
Feed with a balanced liquid fertiliser every 2-4 weeks during the growing season (spring to early autumn). Reduce or stop feeding in winter when growth naturally slows.
