Platt's Black New Zealand Flax is a striking, architectural perennial grown for its bold, upright foliage and dramatic color. This variety of New Zealand Flax features narrow, sword-shaped leaves in deep, smoky purple to near-black hues, adding a sophisticated contrast to green and brightly colored plants. Growing to about 2 to 3 feet tall and wide, Platt’s Black is more compact than other phormiums, making it ideal for small gardens, modern landscapes, and container plantings where space and structure are key design elements.

Tough and low-maintenance, Platt’s Black thrives in full sun to part shade and tolerates a range of soil types, as long as drainage is good. It is drought-tolerant once established, wind-resistant, and even handles coastal conditions, making it a reliable choice for challenging environments. With year-round appeal and minimal upkeep, this cultivar works beautifully in mass plantings, as an accent in mixed borders, or in contemporary pots for patios and entryways. Whether used for contrast, texture, or its deep, moody color, Platt’s Black adds lasting impact to any garden design.
