  New Zealand Flax
 

New Zealand Flax (Phormium sp.) are large strap-leafed evergreen perennials that for many years were placed in the Agave family (Agavaceae) - Current taxonomic treatment has recently created the family Phormiaceae into which Phormium and Dianella have been placed. There are two species in the genus. Phormium tenax, the Coastal Flax, is the larger and more common plant in cultivation; its long strap leaves in shades of green, bronze and maroon are a familiar sight to gardeners in California. The Mountain Flax, Phormium cookianum (P. coloensoi), is a smaller, more graceful plant that has just lately been gaining popularity in California. Both of these plants are useful and attractive in the right situation, but the real gems are the colorful cultivars and interspecific hybrids that have been recently introduced into the California nursery trade. The recent creation of the Phormiaceae and restoration of historical names has lately added to confusion.

San Marcos Growers has been growing many of the new flax cultivars since 1983. See History of Flax Introduction for a detailed account of how San Marcos Growers became involved in the introduction of new cultivars into the nursery trade. We have grown these plants both as a container crop and a field crop for cut foliage production. Some of our specimen sized plants have been used in exhibits at the Rockefeller Center in New York and at Longwood Gardens in Pennsylvania. In the demonstration garden on the nursery grounds, each variety that we sell has been planted into a garden setting. In the time that we have been growing and selling this group of plants we have learned much about them. We wish to share our observations and experiences with you. In 1986 we printed a handout titled "Cut Me Some Flax: Phormium Hybrids". Since that time we have added new varieties to our list and updated information on many of the previous varieties that we listed. Some of our earlier information was from observation of these plants in New Zealand; now we are able to relate our experience with plants grown in California. Have a look at some of our hybrid flax samples.

Cultural Notes
Cultural practices for the flax hybrids are similar to those for the species with a few exceptions. As a general rule the hybrid flax are not as durable as Phormium tenax and are usually less tolerant to extremely hot or cold temperatures, prolonged dry conditions and heavy soil. We have noted that during the hot and dry Santa Ana conditions we experience in Southern California, sunburn is likely on the cultivars that have the graceful weeping leaves; cold temperatures below 20 F are likely to scald the leaves of these plants as well. In hot inland valleys it would be wise to use these cultivars in bright shade where there is protection from the sun. The upright growing cultivars are affected less by these extremes in temperature. We have found the hybrids to be nearly as drought resistant as Phormium tenax. Plants look much better with occasional irrigation but can survive extensive periods without it; once, we let a planting go the entire summer without watering and the plants remained healthy. There is a tendency for the slower growing hybrids to languish in poor heavy soil. If possible, position plants on a slope or mound when given this soil condition. Phormium plants suffer from few other maladies. Occasional long tailed mealy bug attacks can be controlled through sprays, and snails that often use the underside of the leaves for an abode can be easily picked off or poisoned. The most serious pest we have seen on New Zealand Flax is the New Zealand Flax Mealybug (Balanococcus diminutus). An infestation of this pest threatens the long term health of the plant.

Color Stability
The most serious complaint we have on the hybrid flax is the tendency of the colorful leaf forms to revert back to a green or bronze color. When a shoot of an unwanted color is seen on a hybrid plant, this shoot should be cut off at the base. With some of the hybrids it is the new foliage that is the showiest, and it is often best to remove all of the older leaves as the new ones emerge. In the individual listings below we have indicated the color forms that are least likely to revert by noting them as "Stable". If diligence is used, even the plants most likely to revert can be kept the original color. It should be noted that not all of the shoots with a different color than the original plant are detrimental; Phormium 'Cream Delight', one of the showiest of all of the cultivars, was a vegetative sport from Phormium 'Tricolor'.

Flowering
New Zealand Flax is rarely grown for its flowers, as it is the colorful foliage or striking form that is of primary interest. However, Flax will often flower in the garden in late spring or early summer, and are not only showy but also attract nectar seeking birds. The flowers on Phormium tenax and many of the hybrids are orange-red and held upright on a tall stalk above the foliage. Phormium cookianum, and the hybrids more closely aligned with it, have greenish-yellow flowers that are held horizontally on an arching flower stalk. The fruit that follows is also quite different: P. tenax has its woody bean-like fruit held upright and P. cookianum has twisted dangling fruit. The flowers and dried fruit of both types are useful in large flower arrangements.

What's In A Name?

Flax
We are sometimes asked what the common name "flax" means and why it is applied to several very different plants. The fibrous nature of "flax" plants and their usage for items such as rope and clothing is what links such unrelated plants as the "true" or Asian Flax (Linum usitatissimun) and New Zealand Flax (Phormium sp.). True Flax, and its ornamental relative, Yellow Flax (Reinwardia indica), are both dicotyledons in the Linaceae, or Flax family; the New Zealand Flax are monocotyledons that until recently were placed in the Agavaceae, or Agave Family. On Captain Cook's second expedition to the South Pacific in 1773 Phormium tenax was first described, but it was the early traders who came to New Zealand who noted the similarity between its fiber and that of the true flax. These traders observed the usage of Phormium by the Maori, the Polynesian people who had settled in New Zealand. The Maori tribes used the name "harakeke" for Phormium tenax and "wharariki" for the smaller Mountain Flax, Phormium cookianum. From both of these plants the Maori used the leaves for weaving baskets, mats, head-bands, and other items. They used the fibers of the leaves for making clothing, fishing nets, and ropes. The roots yielded the material to make medicine and nectar was obtained from the flowers as was pollen to make face powder. Even the spent flower stalks were used to make rafts to cross rivers and lakes.

Phormium
It is from the use of the New Zealand Flax leaves in the making of baskets that gives us the scientific name Phormium, which translates from Greek as basket. The recent creation of the Phormiaceae and restoration of historical names has lately added to confusion. While New Zealand botanists insist that Phormium cookianum is the valid name for the mountain flax, many recent texts, including Sunset's Western Garden Book and The Royal Horticultural Encyclopedia of Plants, have adopted the synonym P. colensoi as the current name. With respect to the treatment of the genus in New Zealand we have retained the name Phormium cookianum.
