New Zealand Flax

Phormium

New Zealand flax is a wonderful plant to use in place of an ornamental grass where you need more texture and a pop of color. This low-maintenance plant has no problem with heat in the summer, and it works great in containers. With many color options to choose from, you'll have a hard time finding a New Zealand flax you don’t like!

Propagation

Colorful Combinations

New Zealand flax is grown primarily for its colorful, architectural foliage. The striking lance-shaped leaves can come in many colors—the combinations are endless. This plant's large selection originates, surprisingly, from only two species. All of these plants came in foliage shades of green and a few bronze-red. Now, there are countless variegated forms in differing heights and mixes of color from pinks, whites, reds, burgundies, and every shade in between.

New Zealand Flax Care Must-Knows

New Zealand flax can be grown easily in any average, well-drained soil. These plants like to remain evenly moist if possible, but once they are established, they have no problem with drought every now and then. Depending on the parentage of a specific cultivar, however, some may require a little more water than others.

Generally, New Zealand flax prefer full sun. Full sun ensures plants have the most intense coloration, as well as the best, most dense habits. Some varieties, especially ones with large amounts of white foliage, will do better in part sun. These varieties are especially appreciative of shade from the hot afternoon sun, as they can be susceptible to leaf burn. 

In many cases, the flowers of New Zealand flax are an afterthought. They are not as showy as the foliage itself and rarely appear on the plants. When they do, they are held on thin stems high above the foliage. The blooms themselves are generally insignificant, small blooms of usually yellow or red. These blooms are generally heavy producers of nectar, making them a favorite for hummingbirds and other nectar feeders.

As these plants continue to grow, keep in mind that they can get quite large, especially when in the ground. In containers, the size is usually a little more restrained, but they can still quickly fill the pots. If plants do become too large, they can easily be divided to make more new plants. Simply dig the plants up and cut them into smaller chunks or, if possible, gently separate clumps into pieces with several growths per plant. Then repot and water well.

New Innovations

These plants are highly sought after as tough and rugged accent plants for many different uses, especially their drought resistance. With that in mind, breeders are constantly coming out with improvements on old varieties. Factors like better disease resistance, brighter colors, and more drought tolerance are common things researchers are working toward. Because there are only two species in this plant family to work with, there are no groundbreaking new innovations happening with New Zealand flax.

plant New Zealand Flax With:

Phlox
Phlox are one of those bounteous summer flowers that any large sunny flowerbed or border shouldn't be without. There are several different kinds of phlox. Garden and meadow phlox produce large panicles of fragrant flowers in a wide assortment of colors. They add height, heft, and charm to a border. Low-growing wild Sweet William, moss pinks, and creeping phlox are effective as groundcovers, at the front of the border, and as rock and wild garden plants, especially in light shade. These native gems have been hybridized extensively to toughen the foliage against mildew problems; many recent selections are mildew-resistant. Phlox need amply moist soil for best overall health.
Sunflower, perennial
A big, bodacious, beautiful plant, perennial sunflower is imposingly tall and floppy with large (up to 4 inch), bright yellow flowers that form in loose clusters. Most of these natives thrive in full sun and are not fussy about soil. The taller ones may need support. Excellent for cut flowers.
Dahlia
Nothing beats a dahlia for summer color. Growing these varied, spiky flowers is like having a box of garden crayons at your disposal. The flowers form on branching, fleshy stems or open in solitary splendor on the bedding-plant types in mid to late summer. Several different flower categories, from the petite mignonettes to the gigantic dinner-plate dahlias, offer possibilities for any space. Expert dahlia growers recommend pinching off the first crop of side flower buds to encourage vigorous plant branching and larger flowers in peak season. All dahlias are fodder for brilliant seasonal cut bouquets and are always one of the most popular cut flowers at local farmers markets. The blooming season extends into fall and is only halted by the first frost. Gardeners in climates colder than Zone 8 should cut back the withered foliage after the first frost and dig up tubers to store over winter. For a fast start with dahlia plants before it's safe to plant outdoors, pot the tubers up, water sparingly, and grow in a sunny location until sprouts appear, and then transplant outdoors after the last frost.
Anemone
Anemones are lovely, delicate flowers that dance atop slender stems, giving them their poetic common name—windflower. Depending on the type, anemones bloom in spring, summer, or through fall with pretty, slightly cupped flowers in rose, pink, or white rising over distinctive, deeply lobed foliage. Plants grow best in partial shade but tolerate full sun in Northern regions. In some cases, you may need to divide plants frequently to prevent them from overtaking neighboring perennials.
