Little Rev Flax Lily - 1 Gallon

Little Rev Flax Lily is a compact, clumping evergreen perennial in the family Asphodelaceae (formerly Phormiaceae), native to the varied eucalyptus forests, grasslands, and coastal regions of southern Australia. The cultivar name 'DR5000' was discovered in 1996 in Clarendon, New South Wales, as a seedling selection from the unpatented Dianella revoluta 'DR4000'. It received US Plant Patent PP17,719 in May 2007 and quickly became recognized as one of the most versatile and well-behaved ornamental grass-like plants available to Western gardeners. The plant spreads slowly via short rhizomes to form a dense, tidy clump. Its narrow leaves — roughly 1/4 to 1/2 inch wide — are held in uniform, upright fans and feature a yellow-green upper surface contrasted with a more visible cool blue-green underside, lending the overall plant a distinctive blue-toned appearance. Delicate, star-shaped flowers in deep violet-blue appear on branching panicles that rise nearly to 3 feet in height above the foliage from spring through summer. The genus name Dianella honors Diana, the Roman goddess of the hunt and queen of the woods, while the species epithet revoluta refers to the in-rolled margins of the leaves. The common name "black-anther flax lily" refers to the dark anthers visible within the blue flowers.

Note: Plants grown in rich soils with generous irrigation in warm inland California climates have been observed reaching close to 3 feet in height. Spacing plants 18 to 24 inches on center is recommended for mass plantings to achieve a seamless, weed-suppressing groundcover effect.

Little Rev Flax Lily has proven highly resilient through field trials in California, tolerating high inland summer temperatures, heat reflected from paved surfaces, coastal salt winds, and moderate frost events. It is well suited to the warm, dry summers and mild winters of Southern Oregon and Northern California, including both coastal and inland valley conditions. In colder climates at the edge of its hardiness range, a light layer of mulch applied over the root zone in late fall will provide additional protection.

Little Rev Flax Lily performs best in full sun to partial shade. It is remarkably adaptable across a wide light range:

• Full Sun (6+ hours of direct sun): Produces the most vibrant blue-green foliage color and the most compact, upright growth habit. Ideal for open borders, medians, and parking lot islands.
• Partial Shade (3 to 6 hours of direct sun): Plants remain healthy and attractive, though growth may be slightly more open. Well suited to dappled light under open-canopy trees or along east- or west-facing exposures.
• Deep Shade: Not recommended for prolonged, dense shade. Plants may become floppy and lose the tight, architectural form that makes this cultivar so desirable.

In the hottest inland areas of Southern Oregon and Northern California, light afternoon shade during peak summer heat can help prevent leaf tip scorch while still allowing excellent growth and flowering.

One of Little Rev Flax Lily's greatest strengths is its adaptability to a broad range of soil types and pH levels. Key preferences include:

• Soil Texture: Performs well in sandy, loamy, clay-loam, and even moderately heavy clay soils, provided drainage is adequate. Avoid chronically waterlogged soils.
• Drainage: Well-draining soil is the single most important requirement. Root rot is the most common problem and is almost exclusively caused by standing water around the root zone.
• Soil pH: Highly adaptable; thrives in acidic, neutral, and mildly alkaline conditions. A target pH of 6.0 to 7.0 is ideal for optimal nutrient uptake, but this plant has performed well in soils up to pH 8.0 in alkaline coastal conditions.
• Soil Amendment: In poor native soils, incorporating compost or aged organic matter before planting will improve structure and support early establishment.
• Salt Tolerance: Highly tolerant of salt spray, making it an excellent choice for coastal gardens and seaside plantings.

Proper watering is essential during establishment, after which Little Rev Flax Lily becomes a remarkably low-water plant.

• At Planting: Water thoroughly immediately after planting to settle the soil around the roots. Keep the root zone consistently moist (but not saturated) for the first 4 to 8 weeks while the plant establishes.
• First Growing Season: Water deeply once or twice per week, allowing the soil to begin to dry slightly between waterings to encourage deep root development.
• Established Plants: Once established (typically after the first full growing season), irrigation can be reduced dramatically. In most Southern Oregon and Northern California gardens, occasional deep watering every 2 to 3 weeks during summer is sufficient. In cooler coastal areas, natural rainfall may be adequate.
• Watering Method: Deep, infrequent irrigation with a soaker hose or drip system is preferred over frequent shallow watering. Morning watering reduces risk of fungal leaf issues.
• Overwatering Caution: Yellowing leaves and a wilting, soft appearance despite wet soil are the primary signs of overwatering or root rot. Always confirm soil moisture before irrigating.

UC landscape irrigation trials confirmed that Little Rev Flax Lily maintains good to very good aesthetic ratings across all irrigation levels, from regular to very low water schedules, making it an excellent candidate for drought-tolerant and water-wise landscape designs.

Little Rev Flax Lily is a light feeder and does not require heavy fertilization. A simple seasonal approach supports healthy growth and vibrant foliage color without the risk of over-fertilizing:

• When to Fertilize: Apply fertilizer once in early spring as new growth begins. A second light application in early summer is optional for plants in containers or very lean soils.
• What to Use: A balanced, slow-release granular fertilizer (such as a 10-10-10 or similar NPK ratio) applied at the manufacturer's recommended rate works well. Organic options such as composted plant material, aged manure, or blood and bone meal provide a broader spectrum of micronutrients and support beneficial soil microbes.
• Application Method: Broadcast granular fertilizer around the drip line of the plant and water in thoroughly. Avoid placing fertilizer directly against the base of the leaves or crown.
• Signs of Nutrient Deficiency: Yellowing older leaves may indicate a nitrogen deficiency; a single balanced fertilizer application typically resolves this.
• Avoid Over-Fertilizing: Excess nitrogen promotes lush, floppy growth and can reduce the plant's drought tolerance and compact habit. Less is more with this cultivar.

Little Rev Flax Lily is one of the most low-maintenance ornamental grass-like plants available, requiring only minimal attention to remain tidy and attractive year after year.

• Routine Tidying: Remove older, browning lower leaves by hand as needed throughout the growing season. This keeps the clump looking fresh without disrupting new growth at the center.
• Deadheading: Spent flower stalks can be clipped at the base after blooming and berry drop to maintain a neat appearance, though this is entirely optional.
• Hard Rejuvenation Cut: Every 2 to 3 years, or when the clump begins to look tired, the entire plant can be cut back to approximately 2 inches above the ground. This is best performed in late fall through early spring before new growth emerges. The plant rebounds quickly with fresh, vigorous foliage.
• Division: Divide overcrowded clumps in late winter to early spring or in fall. Use a sharp, clean spade to separate the rhizomes and replant divisions at the same soil depth. Water thoroughly after dividing. Note that as a patented cultivar, divisions are for personal garden use only and may not be propagated for sale.
• Mulching: Apply a 2 to 4 inch layer of coarse organic bark mulch around the base of the plant (keeping mulch off the leaves and crown) to conserve soil moisture, moderate root temperature, and suppress weeds. Refresh the mulch layer every 1 to 2 years.

1. Choose the Right Location: Select a site with full sun to partial shade and well-draining soil. Avoid low spots where water pools after rain.
2. Prepare the Soil: Loosen the planting area to a depth of 12 inches. Amend with compost if the native soil is very poor, compacted, or extremely sandy. In heavy clay, improve drainage by mounding the planting bed slightly or incorporating coarse grit and compost.
3. Dig the Hole: Dig a hole twice as wide as the root ball and approximately the same depth. The crown of the plant should sit level with or very slightly above the surrounding soil grade.
4. Remove from Container: Gently remove the plant and loosen any circling roots. If roots are densely pot-bound, score the outer edges lightly with a clean knife to encourage outward growth.
5. Set the Plant: Place in the center of the hole. Backfill with native or amended soil, firming gently to eliminate air pockets.
6. Water In: Water thoroughly and deeply immediately after planting. Apply a layer of organic mulch 2 to 4 inches deep, keeping mulch several inches away from the leaf bases.
7. Mass Planting Spacing: Space plants 18 to 24 inches on center for a groundcover effect. Plants will gradually fill in to form a continuous, weed-suppressing carpet.

As a fully evergreen perennial, Little Rev Flax Lily provides year-round structure, color, and texture in the garden — an especially valuable quality in mixed borders and modern landscapes where off-season visual interest is important.

Little Rev Flax Lily's compact size, refined texture, and architectural form open up a broad range of design applications:

• Border Edging: Plant in single or double rows along pathways, driveways, and garden beds for a clean, repeating linear accent.
• Mass Groundcover: Planted 18 to 24 inches on center, Little Rev creates a dense, weed-suppressing carpet in place of traditional turf grass, particularly effective on slopes or in low-irrigated zones.
• Specimen or Accent Plant: A single clump in a gravel garden, rock garden, or contemporary container planting makes a strong architectural statement.
• Modern and Minimalist Gardens: The precise, uniform form pairs beautifully with clean architectural lines, concrete, steel, and gravel — a natural fit for contemporary design styles prevalent in Southern Oregon and Northern California.
• Coastal Gardens: Exceptional salt tolerance makes it one of the best choices for beach-adjacent plantings, coastal medians, and seaside borders.
• Erosion Control: Dense fibrous root system stabilizes slopes and embankments, including moderately exposed coastal locations.
• Median Strips and Streetscapes: Tough, heat-tolerant, and low-maintenance — well suited to road verges, roundabouts, and urban planting strips.
• Poolside Planting: Evergreen, non-invasive, and tolerant of reflected heat and occasional mist; an elegant poolside accent without the leaf mess of deciduous plants.
• Container Accent: Well suited to large pots, planter boxes, and courtyard containers where its upright form provides a strong vertical element.

Little Rev Flax Lily's cool blue-green foliage, upright form, and low-water needs pair exceptionally well with a wide range of complementary plants. Consider the following combinations for inspired garden designs:

• Ornamental Grasses: Karl Foerster Feather Reed Grass, Blue Oat Grass (Helictotrichon sempervirens), or Mexican Feather Grass provide contrasting movement and texture alongside the rigid flax lily clumps.
• Lavender (Lavandula spp.): Shared preferences for sun, well-drained soil, and low water create a natural pairing; purple lavender blooms harmonize beautifully with the violet-blue flax lily flowers.
• Agave and Succulent Accents: Bold, sculptural succulents such as Agave attenuata or Yucca provide dramatic contrast in scale and form in dry, modern garden schemes.
• Salvia (Salvia nemorosa, S. greggii): Low-water flowering salvias in complementary blue, purple, or pink tones make excellent neighbors in sunny, drought-tolerant borders.
• Variegated New Zealand Flax (Phormium tenax): A classic pairing — the bold, larger Phormium provides a backdrop of contrasting scale and color that highlights Little Rev's fine texture and blue tones.
• Rosemary (Salvia rosmarinus): Similar cultural requirements; the soft silver-green of rosemary contrasts well with the cool blue foliage of Little Rev.
• Rockrose (Cistus spp.): Drought-tolerant, sun-loving flowering shrubs that share the same water-wise palette and complement Little Rev in Mediterranean-style plantings.
• Native Bunch Grasses: California natives such as Purple Needlegrass (Stipa pulchra) or Idaho Fescue (Festuca idahoensis) partner naturally in regionally inspired, low-maintenance landscapes.

Little Rev Flax Lily is considered exceptionally resistant to pests and diseases. UC landscape irrigation trials rated it as having excellent pest and disease resistance across all irrigation levels. Under normal garden conditions, healthy, well-sited plants rarely experience serious problems. The following issues are occasionally encountered:

• Root Rot (Phytophthora spp.): The most significant risk factor; caused by poorly draining soils or overwatering. Symptoms include soft, darkened roots, wilting despite wet soil, and yellowing lower leaves. Prevention through proper drainage and restrained irrigation is far more effective than treatment. Affected plants should be removed and replanted in improved drainage conditions.
• Leaf Spot / Fungal Diseases: Occasional fungal leaf spots may appear, particularly when foliage remains wet. Avoid overhead irrigation; if present, remove affected foliage and improve air circulation. Consult a local horticulturist before applying fungicides.
• Aphids: Rarely a serious problem; can be managed by a strong spray of water or by encouraging beneficial predatory insects in the garden.
• Scale Insects and Mealybugs: Occasionally observed; treat with insecticidal soap or horticultural oil if infestations are established. Remove affected foliage where possible.
• Spider Mites: May occur in hot, dry conditions. Fine webbing on leaves and stippled foliage are telltale signs; increase irrigation and treat with neem oil or insecticidal soap if needed.
• Leaf Tip Scorch: Brown leaf tips in intense sun or extreme heat are typically a cultural issue rather than a disease; ensure adequate root zone moisture during peak summer heat.

Maintaining healthy growing conditions — appropriate drainage, restrained irrigation, and good air circulation — is the most effective approach to preventing the vast majority of issues with this plant.

Little Rev Flax Lily is an excellent candidate for container and patio gardening, offering architectural form and year-round color in confined spaces:

• Container Size: Choose a container that is at least 12 to 16 inches in diameter and depth to accommodate the plant's fibrous root system with room to grow. Larger containers (18+ inches) allow for the most vigorous, attractive specimens.
• Potting Mix: Use a high-quality, well-draining potting mix. Adding 20 to 30 percent perlite or coarse sand to a standard potting soil improves drainage and reduces the risk of root rot.
• Drainage: Ensure the container has adequate drainage holes. Elevating the pot slightly allows excess moisture to escape freely.
• Watering: Container plants dry out more quickly than in-ground plantings. Check soil moisture regularly and water when the top inch of potting mix is dry. Never allow the pot to sit in standing water.
• Fertilizing: Apply a balanced, slow-release granular fertilizer at the start of the growing season. Container plants benefit from an additional liquid fertilizer feeding midseason as nutrients leach out with watering.
• Repotting: Repot into a larger container when roots begin emerging from drainage holes or the plant appears rootbound. Late winter to early spring is the preferred time for repotting.
• Placement: Outstanding on patios, decks, balconies, and entryways. Well-suited to both full sun and partially shaded outdoor exposures.

Wildlife Benefits:

• The violet-blue flowers of Little Rev Flax Lily attract native bees, honeybees, butterflies, and other beneficial pollinators. Dianella flowers are particularly favored by buzz-pollinating insects such as native bumblebees.
• Following pollination, the plant may produce small ornamental berries that attract native birds, adding habitat value to residential and commercial landscapes.
• Dense clumps provide shelter and nesting habitat for small beneficial insects and ground-dwelling fauna.

Toxicity:

• All parts of Dianella revoluta are considered harmful if ingested. The plant contains saponin-like compounds that can cause gastrointestinal irritation in humans, dogs, and cats if plant material is consumed in quantity.
• Keep the plant out of reach of young children and pets that may chew on garden vegetation. Skin irritation from prolonged handling is possible for sensitive individuals; gloves are recommended during pruning.
• If ingestion is suspected, contact the Poison Control Center (US: 800-222-1222) or your veterinarian promptly.
