Phormium 'Golden Ray' – Planting & Care Guide

About Phormium 'Golden Ray'

Phormium 'Golden Ray', commonly known as New Zealand Flax, is a striking evergreen architectural plant valued for its upright, sword-like leaves featuring bright golden-yellow centres with contrasting green margins. Its bold foliage provides year-round colour and structure, making it an excellent focal point in both contemporary and traditional gardens.

Forming a graceful clump, 'Golden Ray' typically grows to 1–1.5 metres tall with a spread of 1–1.2 metres. Mature plants may produce tall flower spikes with tubular yellow-green flowers during summer, which are highly attractive to bees and other pollinating insects.

Planting Guide

• Plant in full sun or partial shade.
• Full sun produces the brightest foliage colour.
• Prefers fertile, moist but well-drained soil.
• Suitable for loam, sandy and clay soils with good drainage.
• Improve heavy soils with compost and horticultural grit before planting.
• Dig a planting hole twice the width of the root ball and the same depth.
• Position the crown level with the surrounding soil.
• Backfill with soil, firm gently and water thoroughly.
• Apply a mulch around the base to retain moisture, keeping it away from the crown.
• Space plants approximately 1–1.2 metres apart.

Care & Maintenance

Phormium 'Golden Ray' is easy to grow and requires minimal maintenance.

• Water regularly during the first growing season.
• Once established, water during prolonged dry spells.
• Feed in spring with a balanced slow-release fertiliser.
• Apply fresh mulch annually to conserve moisture and improve soil fertility.
• Remove weeds from around the base.
• Container-grown plants require more frequent watering during warm weather.

Pruning

Very little pruning is required.

• Remove dead, damaged or weathered leaves by cutting them cleanly at the base.
