Blue Heaven Little Bluestem - 1 Gallon

Blue Heaven Little Bluestem is a patented cultivar (PP17,310) of the native North American prairie grass Schizachyrium scoparium, discovered and selected by horticulturist Mary Meyer at the University of Minnesota from a field of Schizachyrium seedlings. It represents a significant improvement over the straight species, exhibiting a much more upright, non-flopping, broom-like clumping habit and more intensely colored foliage in all seasons. The slender, flat, linear leaves are approximately 1/4 inch wide and emerge a striking light blue in spring. Through summer, the foliage deepens to a luminous steel-blue to blue-gray with subtle purple highlights, appearing almost iridescent in direct sunlight. As summer winds down, glossy purple flower panicles emerge above the foliage, followed by fluffy silvery-white seed heads. With the arrival of cool fall temperatures, the entire plant transforms into a breathtaking blend of purples, reds, burgundy, pink, and orange. In winter, the foliage gradually fades to warm beige tones while the persistent seed heads continue to feed wildlife. This grass is marketed under the trade name BLUE HEAVEN and is sold in the United States under Plant Patent PP17,310, issued December 26, 2006.

Blue Heaven Little Bluestem is cold-hardy in USDA Plant Hardiness Zones 3 through 9, demonstrating exceptional adaptability across a remarkably wide range of climates — from the frigid winters of the northern Great Plains to the heat of the Deep South and the warm summers of the Pacific Coast. This broad zone tolerance makes it suitable for nearly all garden regions across the continental United States, including the diverse climates found in Southern Oregon and Northern California. Its deep, extensive root system allows it to withstand both hard freezes and prolonged summer heat and drought with equal resilience.

Blue Heaven Little Bluestem performs best and displays its most vibrant foliage colors in full sun, requiring a minimum of 6 hours of direct sunlight per day. Full sun exposure encourages the most intensely blue summer color, the tightest upright habit, and the richest fall color transformation. While the plant can tolerate partial shade, reduced light levels will result in less vigorous growth, a tendency for the stems to lean or flop, and a notable reduction in foliage color intensity. For the best ornamental performance, choose the sunniest location available. In the hot-summer climates of Southern Oregon and Northern California, full sun siting is ideal, as this warm-season grass actively thrives in heat.

One of Blue Heaven's great strengths is its exceptional soil adaptability. As a native prairie grass, it is naturally adapted to lean, nutrient-poor conditions and will actually perform better in average to dry, well-drained soils than in overly rich or consistently moist ones. Fertile soils can lead to excessive, floppy growth that diminishes the plant's signature upright habit. Blue Heaven tolerates a wide range of soil textures including sand, loam, chalk, rocky or gravelly soils, and even clay — though clay soils must be reasonably well-draining. It is also tolerant of shallow, rocky soils and is an excellent choice for hillsides, slopes, and erosion-prone areas. Regarding soil pH, it adapts to acidic, neutral, and slightly alkaline conditions, thriving across a broad pH range of approximately 5.5 to 7.5. It does not require soil amendment in most garden situations.

Blue Heaven Little Bluestem is a highly drought-tolerant grass once established, making it ideal for water-wise and low-irrigation landscapes. During the first growing season after planting, water regularly — approximately once or twice per week — to help develop a deep, extensive root system. Gradually reduce watering frequency as the plant becomes established, typically after the first full growing season. Once established, Blue Heaven thrives on low to average moisture and requires little to no supplemental irrigation in most climates, relying primarily on natural rainfall. It is important to avoid overwatering or planting in areas with poor drainage or standing water, as consistently wet conditions can promote crown and root rot and also encourage the floppy growth habit that detracts from its ornamental value. In the driest summer conditions of Southern Oregon and Northern California, an occasional deep watering during prolonged heat waves may benefit the plant but is rarely necessary.

Blue Heaven Little Bluestem generally does not require fertilization and actually performs best without it. As a native grass naturally adapted to poor, infertile soils, excess fertility causes overly lush, floppy growth that undermines its prized narrow upright habit and can even weaken the plant's overall structure. Avoid applying high-nitrogen fertilizers. If soil is extremely impoverished and growth is noticeably poor, a single light application of a balanced, slow-release granular fertilizer in early spring — at half the recommended rate — is sufficient. Do not fertilize after midsummer, as late-season feeding can stimulate tender growth vulnerable to early frosts. In most established garden beds with average soil quality, no fertilization program is needed at all.

Blue Heaven is a low-maintenance grass that requires minimal care once established. Its primary annual maintenance task is a single hard cutback in late winter to early spring, just before new growth begins to emerge. Cut the entire clump back to approximately 3 to 6 inches above ground level. This removes the previous season's dried foliage, rejuvenates the plant, and encourages a tidy, robust flush of new blue growth. Avoid cutting back in fall, as the dried foliage, seed heads, and warm winter tones provide valuable aesthetic interest through the colder months and offer important shelter and food for overwintering wildlife. Some gardeners prefer to wait until they see the first signs of new green growth at the base before cutting, which serves as a natural timing guide. No deadheading is required during the growing season. Division is rarely necessary but can be performed in spring every 5 to 7 years if the center of the clump begins to die out.

1. Select a planting site with full sun and well-drained soil. Avoid low-lying areas where water pools after rain.
2. The best time to plant is in spring or early summer, when soil temperatures are warming. This allows warm-season grasses the full growing season to establish strong root systems before winter. Fall planting is possible but less ideal, as the plant may not have adequate time to root in before cold weather arrives.
3. Dig a planting hole that is twice as wide as the root ball and approximately the same depth. Do not amend the soil with compost or fertilizer unless soil is extremely sandy and drains instantly — lean soil is preferred.
4. Remove the plant from its container and gently loosen any tightly circling roots.
5. Position the plant so that the crown (the point where stems meet roots) sits at or just slightly above the surrounding soil level. Planting too deep can lead to crown rot.
6. Backfill with native soil and firm gently around the base. Water thoroughly to settle the soil and eliminate air pockets.
7. Apply a 2-inch layer of mulch around (but not touching) the base of the plant to conserve moisture during establishment.
8. Water regularly for the first 4 to 6 weeks, then begin reducing frequency as the plant establishes.
9. Space multiple plants 30 to 40 inches apart on center for a mass planting or prairie-style grouping.

Blue Heaven Little Bluestem delivers genuine four-season ornamental appeal, making it one of the most valuable year-round performers in the perennial landscape:

• Spring: New shoots emerge flat and a vivid light blue, creating an eye-catching splash of cool color in the garden as perennials around it awaken.
• Summer: Foliage deepens to a bold steel-blue to blue-gray with purple highlights, standing upright in tight, columnar form. The almost iridescent quality of the blue color is most striking in direct sunlight. Glossy purple flower panicles begin to rise above the clump in late summer.
• Fall: The plant erupts into its most spectacular season, with foliage shifting through an extraordinary range of purple, burgundy, red, pink, and orange — one of the most dramatic fall color displays of any ornamental grass. Seed heads mature to showy fluffy white, adding additional texture.
• Winter: The warm beige and tan tones of the dried foliage and persistent feathery seed heads provide structure, movement, and visual interest in the winter garden while supplying food and cover for wildlife.

Blue Heaven Little Bluestem is an extraordinarily versatile landscape plant suited to a wide range of garden styles and design applications:

• Mixed perennial borders: Use as a vertical accent or mid-to-back-of-border structural element among flowering perennials.
• Mass plantings and sweeps: Planted in groups of 3, 5, or more, Blue Heaven creates stunning prairie-inspired sweeps that undulate beautifully in the breeze and provide a unified seasonal color display.
• Meadow and naturalistic gardens: Ideal for prairie-style, wildflower meadow, or naturalistic planting designs, alone or blended with native wildflowers.
• Rain gardens: Tolerates occasional inundation and adapts well to rain garden plantings designed to manage stormwater.
• Slopes, banks, and erosion control: Deep root systems help stabilize hillsides and erosion-prone areas.
• Rock and gravel gardens: Thrives in the lean, sharply drained conditions of rock and gravel garden settings.
• Screening and backdrops: Its tall, upright form and dense habit make it effective as a seasonal screen or background for shorter plantings.
• Container gardening: Can be grown in large, deep containers (minimum 15-gallon) on patios or terraces in full sun, provided containers are well-draining.
• Cut and dried arrangements: The feathery seed heads are attractive in both fresh-cut and dried floral arrangements.

Blue Heaven Little Bluestem pairs beautifully with other sun-loving perennials and native plants that share its preference for lean, well-drained soils. Consider these companion combinations for outstanding seasonal interest:

• Purple Coneflower (Echinacea purpurea): Bold purple daisy flowers contrast beautifully with the blue summer foliage, and both share the same low-maintenance, drought-tolerant nature.
• Black-eyed Susan (Rudbeckia fulgida): Golden-yellow blooms pop against the steel-blue grass foliage in summer and warm-toned fall colors echo each other in autumn.
• Butterfly Milkweed (Asclepias tuberosa): Vivid orange flowers complement the blue summer foliage spectacularly and attract pollinators alongside the grass.
• Aromatic Aster (Symphyotrichum oblongifolium): Lavender-purple fall blooms create a stunning pairing with Blue Heaven's rich fall foliage colors.
• Goldenrod (Solidago spp.): Bright yellow fall plumes echo the warm amber tones in Blue Heaven's fall display, creating an authentic prairie look.
• Russian Sage (Perovskia atriplicifolia): Silvery stems and hazy purple flowers harmonize with the blue-gray grass foliage throughout summer.
• Blazing Star (Liatris spicata): Upright purple flower spikes complement the grass's vertical form and attract pollinators through summer.
• Sedum 'Autumn Joy' (Hylotelephium): The dusty pink to copper fall flower heads pair naturally with Blue Heaven's autumn color transformation.
• Yarrow (Achillea millefolium): Flat-topped flower clusters in white, yellow, or pink provide a textural contrast to the narrow grass blades.

Blue Heaven Little Bluestem is a powerhouse plant for wildlife and pollinator gardens, offering ecological value across multiple seasons:

• Songbirds: The abundant fluffy seed heads provide a highly nutritious food source for finches, sparrows, juncos, and other seed-eating birds through fall and winter. The persistent seed heads are particularly valuable during winter months when food sources are scarce.
• Pollinators: The flowers attract native bees and butterflies throughout the late-summer blooming period.
• Butterfly and skipper larvae: Little Bluestem serves as a documented larval host plant for at least 9 skipper butterfly species, including the Common Wood Nymph (Cercyonis pegala), the Dakota Skipper (Hesperia dacotae), and Leonard's Skipper (Hesperia leonardus), making it an ecologically significant selection for butterfly gardens.
• Overwintering insects: The dense clump and dried foliage provide vital overwintering shelter for beneficial insects. Female bumblebee queens are known to overwinter at the base of little bluestem clumps, emerging in spring to establish new colonies.
• Small mammals: The dense clump base provides protective cover for small mammals and ground-nesting birds.
• Native ecosystem support: As a true North American native prairie grass, Blue Heaven supports local food webs and native insect communities in ways that non-native ornamental grasses simply cannot.

Blue Heaven Little Bluestem is remarkably trouble-free and is not seriously affected by any common pests or diseases when grown in appropriate conditions. It has earned a reputation as one of the most pest- and disease-resistant ornamental grasses available. The following minor issues are occasionally observed:

• Rust (fungal): Occasional orange or yellowish rust pustules may appear on foliage in very humid conditions or where air circulation is poor. This is rarely serious and typically resolves on its own. Improving air circulation and avoiding overhead irrigation minimizes risk.
• Fungal leaf spots: May occasionally occur in prolonged wet, humid weather but are not typically life-threatening to the plant.
• Aphids: Occasionally observed but rarely in populations large enough to cause significant damage. A strong blast of water from a hose is usually sufficient to dislodge them.
• Spider mites: Can appear during hot, dry conditions. Adequate spacing for air circulation and avoiding water stress help prevent infestations.
• Crown and root rot: The most serious threat, caused not by a specific pathogen but by poorly drained or consistently wet soils. Plant in well-drained sites and avoid overwatering to prevent this entirely.
• Deer and rabbits: While the species as a whole can occasionally be browsed, Blue Heaven is generally considered deer resistant and rabbit resistant due to its texture and taste.

Blue Heaven Little Bluestem can be successfully grown in containers, adding bold vertical form and dramatic seasonal color to patios, entryways, and rooftop gardens. For best results in containers, observe the following guidelines:

• Choose a large, deep container — a minimum of 15 gallons and at least 18 inches deep — to accommodate the plant's extensive root system and support its tall stature.
• Use a well-draining potting mix; consider blending standard potting soil with coarse perlite or grit to improve drainage and replicate the lean, fast-draining soil conditions the plant prefers.
• Ensure the container has ample drainage holes. Do not allow the container to sit in standing water.
• Position the container in a full-sun location — at least 6 hours of direct sun daily — for the best foliage color and habit.
• Container plants require more frequent watering than in-ground plants; water when the top inch or two of soil is dry, but never allow the roots to remain soggy.
• Fertilize lightly — if at all — with a diluted, balanced fertilizer once in early spring. Overfertilizing in containers will cause floppy, weak growth.
• In USDA Zone 7 and colder, container-grown plants may need winter protection (such as moving to an unheated garage or wrapping the pot with burlap) as container roots are more exposed to freezing than in-ground roots.
• Cut back to 3 to 6 inches in late winter or early spring before repotting or allowing the plant to re-grow for the new season.

Little Bluestem (Schizachyrium scoparium) holds a storied place in North American ecological history. It was one of the dominant grasses of the vast tallgrass prairie ecosystem that once blanketed much of central North America, stretching from Alberta and Quebec south through the Great Plains to Arizona and Florida. This prairie ecosystem, now largely converted to agriculture, represented one of the most biodiverse grassland habitats on the planet, and little bluestem was at its heart. The name "bluestem" refers to the distinctive lavender-blue coloration at the base of the stems — a feature most prominent in summer. The genus name Schizachyrium comes from the Greek words meaning "to split" and "chaff," referencing the divided glumes of the flower spikelets. The specific epithet scoparium means "broom-like," describing the plant's characteristic upright, sweeping growth form. Blue Heaven, as a cultivar selected directly from species seedlings, retains all of the native ecological function of the straight species while offering superior garden performance. Its deep, fibrous root system — which can extend several feet into the soil — sequesters carbon, reduces erosion, improves water infiltration, and supports soil biology, making it a genuinely ecological as well as beautiful choice for sustainable landscapes.
