This dramatic selection produces deep burgundy to black foliage; unique and eye catching as a contrasting accent in the garden or massed along borders; also a great center for a mixed container; heat and drought tolerant once established
Black Adder™ New Zealand Flax's attractive large sword-like leaves remain burgundy in color with showy black variegation and tinges of coppery-bronze throughout the year. Neither the flowers nor the fruit are ornamentally significant.
Black Adder™ New Zealand Flax is an open herbaceous evergreen perennial with a shapely form and gracefully arching foliage. Its relatively coarse texture can be used to stand it apart from other garden plants with finer foliage.
This is a relatively low maintenance plant, and is best cleaned up in early spring before it resumes active growth for the season. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.
Black Adder™ New Zealand Flax is recommended for the following landscape applications;
- Mass Planting
- General Garden Use
- Container Planting
Planting & Growing
Black Adder™ New Zealand Flax will grow to be about 4 feet tall at maturity, with a spread of 3 feet. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 30 inches apart. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years.
This plant does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This particular variety is an interspecific hybrid. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
Black Adder™ New Zealand Flax is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Because of its height, it is often used as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
