Squirrel Tail Grass: A Complete Guide to Growing Hordeum jubatum

Introduction to Hordeum jubatum

Hordeum jubatum, commonly known as Squirrel Tail Grass or Foxtail Barley, is one of the most visually striking ornamental grasses available to home gardeners and landscape designers alike. With its feathery, arching seed heads that shimmer in shades of green, pink, and golden wheat as the season progresses, this remarkable plant earns its place in any garden setting. Native to North America and parts of Asia, it has adapted beautifully to cultivation as an ornamental specimen that delivers extraordinary visual impact with minimal effort.

The name “Squirrel Tail Grass” is immediately apparent once you see the plant in full bloom. The nodding, bristled seed heads bear an unmistakable resemblance to a squirrel’s bushy tail, giving the plant a playful, whimsical quality that few other grasses can match. Each stem terminates in a dense cluster of silky awns that can reach several inches in length, creating a soft, feathered appearance that catches every passing breeze and transforms ordinary garden beds into dynamic, living works of art.

Grown from seed, Hordeum jubatum is an annual or short-lived perennial depending on your climate zone, making it an excellent choice for gardeners who enjoy refreshing their plantings each season. A single packet of approximately 80 seeds provides an abundance of planting material, allowing you to experiment with mass plantings, container arrangements, and mixed borders without breaking the garden budget. Its compact growing habit — typically reaching 12 to 24 inches in height — makes it equally at home in raised beds, rock gardens, prairie-style landscapes, and cottage garden settings.

Understanding the Plant’s Characteristics and Ornamental Value

The ornamental value of Squirrel Tail Grass lies primarily in the extraordinary texture and movement it introduces to any planting scheme. Unlike many stiff or upright ornamental grasses, Hordeum jubatum develops a graceful, arching habit with seed heads that sway delicately even in the lightest wind. This kinetic quality makes it a favorite among garden designers who seek to create landscapes that feel alive and responsive to the natural environment rather than static and manicured.

Color progression throughout the growing season is another exceptional feature of this plant. In spring and early summer, the emerging seed heads display a soft green tinged with subtle pink and violet hues. As summer advances, these gradually deepen to shades of warm gold and bronze before fading to a creamy straw color by late summer and autumn. This multi-stage color transformation means the plant offers continuous visual interest across multiple seasons, rather than delivering a single peak moment before fading into the background.

The awns — the long, bristle-like extensions that create the characteristic fluffy appearance — are particularly remarkable in morning or evening light. When backlit by low sun, the seed heads take on an almost luminescent quality, glowing with warm amber and rosy tones that elevate the entire garden composition. Photographers and garden enthusiasts often seek out Hordeum jubatum specifically for these magical lighting effects, which make it one of the most photogenic plants available to home gardeners at any price point.

How to Grow Squirrel Tail Grass from Seed

Starting Hordeum jubatum from seed is a straightforward and rewarding process that requires no special equipment or horticultural expertise. The plant is well suited to direct sowing outdoors, which makes it particularly convenient for gardeners who prefer to skip the indoor seed-starting process entirely. Seeds can be sown directly into prepared garden beds in early spring, as soon as the soil can be worked, or in autumn for germination the following spring. The cold stratification that naturally occurs over winter often improves germination rates when seeds are fall-sown.

For spring sowing, prepare your chosen site by loosening the soil to a depth of around four to six inches and removing any weeds or debris. Scatter the seeds thinly across the surface and press them gently into contact with the soil without burying them deeply — a covering of no more than a quarter inch of fine soil or vermiculite is ideal. Water the area gently with a fine mist to avoid displacing the seeds, and keep the seedbed consistently moist until germination occurs, which typically takes between seven and fourteen days under favorable conditions.

If you prefer to start seeds indoors for an earlier display, sow them in small pots or trays filled with a well-draining seed compost approximately six to eight weeks before your last expected frost date. Maintain temperatures of 60 to 70 degrees Fahrenheit and provide good light to encourage compact, sturdy seedlings. Harden off transplants gradually over the course of a week before moving them to their final outdoor positions, as abrupt transitions from the sheltered indoor environment to outdoor conditions can cause transplant shock and setbacks in early growth.

Optimal Germination Conditions

Successful germination of Hordeum jubatum depends on a few key environmental factors that are important to get right from the beginning. Soil temperature plays a significant role — seeds germinate most reliably when soil temperatures are consistently between 55 and 70 degrees Fahrenheit. Attempting to sow too early in cold, waterlogged soil can result in poor germination or rotting of the seeds before they have a chance to sprout. A simple soil thermometer is a worthwhile investment for gardeners who want to take the guesswork out of timing their sowings.

Moisture management is equally critical during the germination phase. The seedbed must remain consistently moist but never waterlogged, as standing water can deprive germinating seeds of the oxygen they need and create conditions favorable to fungal diseases. In hot, dry weather, this may require gentle watering once or twice per day, while in cooler or cloudier conditions, less frequent watering is typically sufficient. A layer of fine horticultural grit or sand over the sowing area can help retain moisture while also improving drainage and preventing the formation of a hard surface crust.

Light is beneficial to germination for this species, which is one reason the seeds should not be buried too deeply. Placing seed trays or outdoor seedbeds in a bright, open position with access to natural daylight will promote stronger, more consistent germination compared to shaded locations. Once seedlings have emerged and developed their first true leaves, they are remarkably resilient and can be thinned to the desired spacing — generally around six to twelve inches apart — to allow adequate air circulation and room for the characteristic arching seed heads to develop without crowding.

Ideal Growing Conditions and Site Requirements

One of the most appealing aspects of Hordeum jubatum is its exceptional adaptability to a wide range of growing conditions. It thrives in full sun, which encourages the most prolific seed head production and the richest color development, but it will also perform reasonably well in positions that receive only partial sun for part of the day. In hot climates, a degree of afternoon shade can actually be beneficial, preventing the plant from drying out too quickly and extending the period during which the seed heads retain their attractive coloration before fading to straw.

In terms of soil requirements, Squirrel Tail Grass is notably undemanding and will grow in soils that would defeat many more finicky ornamental plants. It tolerates poor, dry, sandy, or gravelly soils with equanimity, and in fact often performs better in leaner conditions than in rich, heavily amended garden soils, which can encourage excessive leaf growth at the expense of the ornamental seed heads. It also demonstrates impressive tolerance of alkaline soil conditions, making it a valuable option for gardeners who struggle with the high-pH soils that are common in arid and semi-arid regions.

Drainage is the one non-negotiable requirement for this plant. Hordeum jubatum does not tolerate prolonged waterlogging and will decline rapidly in poorly drained soils, particularly during cooler months when root diseases are most likely to take hold. If your garden has heavy clay soil, consider incorporating generous quantities of coarse grit, perlite, or sharp sand before planting to improve drainage, or simply grow the plant in raised beds or large containers filled with a free-draining growing medium. This simple precaution will dramatically improve the plant’s health and longevity.

Companion Planting Ideas

Squirrel Tail Grass reaches its full ornamental potential when paired thoughtfully with complementary plants that enhance its distinctive textures and seasonal color transitions. Consider the following companion planting combinations for maximum visual impact in your garden design:

• Echinacea (Coneflowers): The bold, upright flower heads of echinacea create a striking contrast with the soft, arching plumes of Hordeum jubatum. The warm orange, red, and yellow tones of many coneflower varieties harmonize beautifully with the golden and bronze tones that develop in the grass as summer progresses. Together, they create a classic prairie-inspired combination that is both ecologically valuable and visually compelling.
• Salvia nemorosa (Ornamental Sage): The deep violet-blue flower spikes of ornamental sage provide a vivid color contrast against the rosy pink and green hues of young Squirrel Tail Grass seed heads in early summer. Both plants share a preference for well-drained, sunny positions, making them natural companions that thrive under identical growing conditions.
• Nigella damascena (Love-in-a-Mist): The delicate, finely cut foliage and ethereal flowers of nigella echo the feathery texture of Hordeum jubatum, creating a cohesive, soft-textured planting combination. The rounded, decorative seed pods that follow nigella’s flowers provide an additional textural element that extends the visual interest of the combination well into autumn.
• Rudbeckia hirta (Black-Eyed Susan): The cheerful, daisy-like flowers of rudbeckia bring bold yellow tones that glow alongside the amber seed heads of maturing Squirrel Tail Grass in late summer. This combination celebrates the warmth of the late-season garden and attracts a variety of beneficial pollinators and seed-eating birds to the planting area.

Care, Maintenance, and Seasonal Management

Once established, Hordeum jubatum requires very little in the way of ongoing care and maintenance, which is one of the primary reasons it has become such a popular choice among low-maintenance and wildlife-friendly garden enthusiasts. Watering needs are modest once the plant is established in open ground — supplementary irrigation is generally only necessary during extended dry spells in summer, particularly for plants growing in sandy or very free-draining soils. Container-grown specimens will require more regular watering, as pots dry out considerably faster than open ground plantings.

Feeding is rarely necessary and can actually be counterproductive, as noted earlier. If your soil is extremely impoverished, a light top-dressing of balanced granular fertilizer in spring may provide a modest boost to plant vigor, but this is rarely required and should be applied sparingly. Over-fertilization encourages lush, soft growth that is more susceptible to disease and less effective at producing the ornamental seed heads that make the plant worth growing in the first place. The natural lean diet of an unfertilized, well-drained soil is far more likely to deliver the visual results you are hoping for.

Deadheading is a matter of personal preference rather than horticultural necessity. If you wish to prevent the plant from self-seeding — which it can do prolifically in favorable conditions — removing the seed heads before they ripen and disperse is the most effective approach. Alternatively, if you welcome natural self-seeding as a means of maintaining a colony of plants year after year without the need to purchase new seeds, simply allow the heads to mature and shed their seeds naturally. Seedlings that emerge the following spring can be thinned or transplanted as needed to maintain the desired planting density.

Harvesting for Dried Flower Arrangements

One of the most delightful secondary uses of Hordeum jubatum is as a cut and dried grass for use in flower arrangements and decorative displays. The seed heads are most attractive for cutting when they have just reached full development but before they begin to shed their awns, which typically occurs in mid to late summer. Cut stems in the morning when the plants are well hydrated, remove the lower leaves, and gather them into loose bunches for drying. The stems retain their beauty remarkably well when dried, maintaining their feathery texture and transitioning to warm straw tones that complement a wide range of dried floral materials.

For the most attractive dried results, hang the bunches upside down in a warm, dry, well-ventilated location out of direct sunlight. Strong sunlight can fade the subtle pink and violet tones that make freshly cut stems so appealing, while a shaded drying environment helps preserve these softer hues more effectively. Drying typically takes between two and three weeks depending on ambient humidity and temperature. Once fully dried, the stems can be used immediately or stored carefully in a dry environment for use throughout the autumn and winter months in seasonal decorations.

Wildlife Value and Ecological Benefits

Beyond its considerable ornamental qualities, Hordeum jubatum delivers meaningful ecological benefits that make it an excellent choice for wildlife-friendly gardens. The seed heads that give the plant its distinctive appearance are also a valuable food source for a range of seed-eating birds, including sparrows, finches, and buntings. Allowing the plants to set seed and stand through the autumn and winter months provides these birds with accessible, nutritious food during the colder months when other food sources may be scarce, transforming your ornamental planting into a functioning wildlife habitat.

The dense, arching foliage also provides useful ground-level cover for small invertebrates, including beetles, spiders, and other beneficial insects that contribute to natural pest control in the garden. Leaving the dried stems and seed heads in place through winter, rather than cutting everything back immediately after flowering, maximizes this habitat value and supports a richer and more diverse garden ecosystem. A garden that embraces this minimal-intervention approach to seasonal management will typically support significantly higher levels of biodiversity than one that is tidied and cut back to bare soil at the end of every growing season.

From a horticultural sustainability perspective, Hordeum jubatum’s ability to thrive in poor, dry conditions with minimal irrigation, feeding, and chemical intervention makes it a responsible choice for gardeners who are conscious of their environmental impact. Ornamental plants that demand rich soil, regular fertilization, and frequent watering place considerable demands on garden resources, while drought-tolerant, low-maintenance species like Squirrel Tail Grass allow gardeners to create beautiful, dynamic outdoor spaces with a much lighter ecological footprint. In an era of increasing concern about water conservation and sustainable land management, this is a quality that deserves significant recognition.

Potential Challenges and How to Address Them

While Hordeum jubatum is generally a robust and trouble-free plant, there are a small number of potential challenges that gardeners should be aware of when planning their plantings. The most commonly encountered issue is the plant’s tendency toward vigorous self-seeding in conditions that suit it well. In warm, dry climates with free-draining soil, escaped seedlings can appear some distance from the original planting and may become difficult to control if the garden is not monitored regularly. Deadheading promptly after flowering is the simplest and most effective way to prevent unwanted spread.

The awns of Hordeum jubatum, while beautiful, are also mechanically adapted for dispersal and can become embedded in the fur of pets and livestock, potentially causing irritation or injury if they penetrate the skin. For this reason, the plant is not recommended for gardens where dogs or cats spend significant time off-leash, particularly during and after the seed-shedding period. Similarly, it should be used with caution in pastures or areas grazed by horses, sheep, or other livestock, as ingestion of the awns can cause oral and digestive tract damage in animals.

Fungal diseases, particularly rust and powdery mildew, can occasionally affect plants growing in excessively humid or shaded conditions with poor air circulation. The best prevention is always good site selection — ensuring the plants are grown in an open, sunny, well-ventilated position with the free-draining soil conditions they prefer. If disease does appear, removing and disposing of affected material promptly and avoiding overhead watering will help contain the problem. Organically acceptable fungicidal sprays can be applied as a last resort, but healthy plants in appropriate conditions rarely require chemical intervention of any kind.

Summary of Key Growing Tips

1. Sow seeds directly outdoors in spring or autumn in a sunny, well-drained position for best results and minimal transplant stress.
2. Avoid heavy, waterlogged soils — improve clay-based ground with coarse grit or grow in raised beds and containers filled with free-draining compost.
3. Resist the temptation to over-fertilize — lean soils produce the best ornamental seed heads and the most resilient, compact plants.
4. Harvest stems for drying just as the seed heads reach full development, before the awns begin to shed, for the most attractive and long-lasting dried material.
5. Allow some plants to self-seed naturally if you want a self-sustaining colony, but monitor for unwanted spread and deadhead plants in less appropriate areas.
6. Leave dried stems standing through winter to provide food and habitat for wildlife, cutting back to ground level in early spring before new growth emerges.

With its extraordinary visual qualities, exceptional adaptability, and meaningful ecological value, Hordeum jubatum stands as one of the most rewarding and versatile ornamental grasses available to home gardeners today. Whether you are creating a sweeping prairie-style border, a low-maintenance rock garden, a wildlife-friendly naturalistic planting, or simply seeking a few packets of unusual seeds to inject texture and movement into an established scheme, Squirrel Tail Grass deserves a prominent place on your planting list. From a single packet of eighty seeds, you can transform an ordinary garden space into something genuinely extraordinary — a testament to the remarkable power of this humble but magnificent grass.
