Striking foliage, delicate blooms, and small berries ensure the Coolvista™ Dianella provides visual interest throughout the growing season. This plant is also known as Dianella revoluta ‘Allyn-Citation,’ blueberry lily, blue flax-lily, or black-anther flax-lily. This clump-forming ornamental grass features thin, flat blue-gray foliage that tapers to a point. Deep blue to purple inflorescences hover above the blades of grass in the spring and summer and later transition to blue-colored berries that last for several months.
Once established, this plant is very hardy and can comfortably live in various conditions. The upright, spiky foliage adds color and texture to borders, mass plantings, and containers. This easy-care plant is heat and drought tolerant, ensuring it can handle the summer heat and still look amazing. The Coolvista™ Dianella lives as a perennial in USDA zones 8 through 11.
Coolvista™ Dianella Plant Care
This plant requires full sun to part shade, and 4 to 6 hours of sunlight is enough to sustain growth. Established plants will need water during an extended drought, and newly planted plants will need water when the top few inches of the soil dry out. The soil should be well-draining and mildly acidic or neutral. Feed the plant by placing several inches of organic compost around the base during the spring or apply a slow-release fertilizer. Remove spent blooms and any damaged growth.
This plant is a perennial in warmer areas, but cover the plant if the forecast calls for chilly weather. The greenery will die back if the plant is exposed to cold weather, and if this happens, trim back the dead growth, and new foliage should appear in the spring.
Coolvista™ Dianella Plant Spacing
This spikey grass grows 1 to 2 feet tall and just as wide. Coolvista™ Dianella can be planted as close as 8 to 12 inches apart to create a continuous planting of lush foliage. Space the plants 2 feet apart for individual plantings.

Plant Addicts Warranty - 1 Year (Extra Purchase Required)
We encourage all plant lovers to purchase the Plant Addicts Warranty, whether you're a new gardener or an expert. There are many variables outside of anyone's control that can cause a plant to die. Hungry animals, drought, poor soil conditions, over watering, diseases & pests are all good examples of what can cause plants to die. The Plant Addicts Warranty is a 1 year warranty protecting you from all of the unknowns and will replace your plant if something were to happen to it.
The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs. SImply let us know if your plant has died within 1 year of receiving it and we will get you a new one shipped out as soon as possible (depending on the time of the year and availability). We may ask for photos for documentation purposes, but we try to make the process as easy as possible.

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
