Phormium cookianum 'Emerald Gem' is a stunning ornamental plant commonly known as New Zealand Flax. Here's a brief description and some tips on its growing conditions:




  • Appearance: 'Emerald Gem' is a compact variety of Phormium cookianum, featuring vibrant green leaves that arch gracefully. The foliage forms dense clumps, providing an attractive accent to gardens or landscapes.
  • Size: It typically reaches a height of around 60cm with a similar spread, making it suitable for both small and large spaces.
  • Flowers: In summer, it may produce small, inconspicuous flowers on tall stalks. However, the main attraction is its striking foliage rather than its flowers.


Growing Conditions:


  • Sunlight: Phormium cookianum 'Emerald Gem' thrives in full sun to partial shade. It prefers at least six hours of sunlight per day for optimal growth and vibrant foliage coloration.
  • Soil: Well-draining soil is essential for this plant. It tolerates a wide range of soil types, including sandy and loamy soils, but it dislikes waterlogged conditions. Ensure good drainage to prevent root rot.
  • Watering: While established plants are somewhat drought-tolerant, it's best to water them regularly, especially during dry spells. Water deeply but infrequently to encourage deep root growth.
  • Temperature: It is tolerant of a range of temperatures but prefers mild to warm climates. It can withstand light frosts once established but may suffer damage in prolonged freezing conditions.
  • Fertilization: Feed 'Emerald Gem' with a balanced, slow-release fertilizer in spring to promote healthy growth and vibrant foliage. Avoid excessive fertilization, as it can lead to lush growth prone to flopping.
  • Maintenance: Remove any dead or damaged leaves to maintain the plant's appearance and prevent pests or diseases. Dividing overcrowded clumps every few years can rejuvenate the plant and promote better growth.


Overall, Phormium cookianum 'Emerald Gem' is a low-maintenance, versatile plant that adds year-round interest to gardens, borders, or containers. With the right growing conditions, it can thrive and become a striking focal point in any landscape.
