Phormium tenax 'Evening Glow' – Planting & Care Guide

About Phormium tenax 'Evening Glow'

Phormium tenax 'Evening Glow', commonly known as New Zealand Flax 'Evening Glow', is a striking evergreen architectural plant grown for its dramatic, upright foliage in rich shades of bronze-red, burgundy and pink, edged with olive green. Its vibrant colouring intensifies in full sun, making it an eye-catching feature throughout the year.

Forming a strong, upright clump, 'Evening Glow' typically grows to 1.2–1.8 metres tall with a spread of 1–1.5 metres. Mature plants may produce tall flower spikes bearing tubular reddish flowers in summer, which are highly attractive to bees and other pollinating insects.

Planting Guide

• Plant in full sun or partial shade.
• Full sun produces the richest foliage colours.
• 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 clear of the crown.
• Space plants approximately 1–1.5 metres apart.

Care & Maintenance

Phormium 'Evening Glow' is an easy-care plant once established.

• 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.
• Keep the base free from weeds.
• Container-grown plants should be watered more frequently during warm weather.
• Avoid prolonged waterlogging, especially in winter.

Pruning

Minimal pruning is required.
