Published Date : February 10, 2022

dianella plant

The genus dianella is comprised of around 40 flowering plants in the asphodelaceae botanical family, which are mainly monocots. A monocotyledon is a type of flowering plant that produces stalkless leaves that bear a single seed; some examples of these are most grasses, palm trees or lilies.

Dianella is more commonly known as a flax lily. Flax lilies are a very sturdy perennial plant that can perform like an ornamental grass on your property. They are admired for their beautiful foliage primarily, but also for their dainty purple flowers and metallic berries.

The dianella is an absolute bargain when it comes to plants. It can thrive in shade, it doesn’t mind being crowded, it is tolerant of urban pollution, it’s deer resistant, and requires little to no maintenance. Keep reading to find out if the dianella will be the new plant in your garden!

What are Some Dianella Species?

Tasmanian Flax Lily (Dianella Tasmanica)

 dianella plant

Also known as the Tasman flax lily, dianella tasmanica is an herbaceous perennial herb that is native to southeastern Australia.

These flax lily plants grow flower stems of up to 1.5 meters in height that bear blue star shaped flowers in the spring. In the summer it will bear violet berries. Leaves are keeled with finely toothed margins.

Blue Flax Lily (Dianella Revoluta)

dianella plant

Also known as the black panther flax lily, dianella revoluta is a tufted perennial herb that is endemic to Australia and grows prosperously there.

This dianella variety grows folded, grass like leaves that can be up to 33 inches tall. Flower stems only reach about 6 inches in height and bear blue or violet flowers that are borne in clusters of 9. Flowers occur in the spring which bring about purple berries in the summer.

Blue berry Lily (Dianella Caerulea)

dianella plant

Also known as the paroo lily, dianella caerulea is native to the eastern side of Australia and Tasmania.

This species is a scrappy perennial plant that grows to be nearly 1 meter tall with dark green bladed leaves with toothed margins. It bears small blue flowers in the mid spring and indigo berries in the summer.

What do Dianella Plants Look Like?

Flowers

Dianella flowers are borne in the spring time and emerge as star shaped flowers with 3 sepals (that look and act just like 3 petals). At the center lies golden colored anthers. Flowers will usually bloom in early spring to mid spring.

Flowers are usually blue or purple, though some cultivar types bear white flowers. Flowers are bisexual and contain one superior ovary. The dianella plant, once pollinated, will produce fruit in the form of small berries that range in blue or purple colors.

Leaves

Though dianella flowers are lovely, these plants are more valued for their incredibly ornamental foliage. Blade-like leaves fan out from a central clump, and each leaf can grow to be up to 30 inches in height!

These usually linear leaves have overlapping bases. Leaves are usually a light green, though they can sometimes be dark green, they can have white striped accents or purple striped accents too!

Growth Pattern

The dianella grows from rhizomes, which are bulbous roots that grow underground (similar to iris‘). They grow very vigorously from these rhizomes and they will proliferate exuberantly with regular watering.

From a rhizome grows long bladed leaves and flower stalks that bear that star shaped flowers. Heights will vary depending on the dianella species, but many will grow to be over 1 meter tall.

Where is Dianella Native to?

Dianella plants occur naturally in Africa, southwestern Asia, the Pacific Islands, and New Zealand and Australia as well. They tend to grow most prosperously in Australian regions like Tasmania and the moist shaded forests of Victoria.

These plants are quite cold hardy as well and can exist in USDA growing zones 7 through 11 throughout the world. As long as they receive a certain amount of shade and water, they will grow happily.

How do you Grow a Dianella?

Dianella is a perfectly low maintenance plant. If you happen to be looking for something that is easily maintained, doesn’t need regular pruning, doesn’t have specific growing requirements, and still produces attractive foliage, flowers, and fruit, the dianella is the plant for you!

Propagation can be done either from collecting ripe seeds and sowing them by hand, or by collecting rhizomes and dividing them in the spring.

The first step is to pick the ideal place on your property. Ensure the area has a minimum of light shade, and that the soil is moderately well drained. If soil is low in nutrients, simply incorporate compost or manure to increase its quality.

If propagating through rhizome division, plant the rhizome 6 inches deep in the soil with the eye of the bulb pointing up. It should begin taking root within a few short weeks. It is advised to water young plants generously until they are well established, where they will then be drought tolerant.

If planting from seed, ensure that seeds aren’t pushed too deep into the soil and that only a light layer of soil is covering them. They require a certain amount of sunlight during their establishment period. Take care not to water directly onto the soil so as to not dislodge the seeds.

What are the Growing Conditions of Dianella Plants?

Soil Type

Dianella plants can tolerate many soil types. They are entirely tolerant of clay soil and sandy soil, and are tolerant of temporarily waterlogged soils as well. That being said, they perform best in well-drained soil.

Sun Exposure

Dianellas prefer to exist in partial shade conditions or in full shade conditions. They will still be able to produce productive flower blossoms in light shade.

Water Level

Well established dianella plants are drought tolerant as long as it is temporary. Their native growing regions experience frequent drought, and this is a good indicator of how often they should be watered.

Dianellas do not need to have completely moist soil in order to thrive. It is safe to wait until soil has completely dried out before watering again.
