Dwarf Fountain Grass

What is Dwarf Fountain Grass?

Dwarf Fountain Grass (scientifically known as Pennisetum alopecuroides or Pennisetum setaceum ‘Hameln’ for the dwarf variety) is a compact form of ornamental fountain grass that is beloved for its arching, fine-textured foliage and attractive bottlebrush-like flower spikes. Its fountain-like growth habit gives it a soft, cascading appearance, making it a beautiful choice for borders, garden beds, and container planting.

This grass typically grows to a height of around 2 to 3 feet (including its flower spikes), making it a smaller, more manageable version of the standard fountain grass, which can grow taller. Its neat, rounded shape and low-maintenance qualities make it ideal for smaller gardens, urban landscapes, or even patios.

Dwarf Fountain Grass is a perennial plant, which means it will come back year after year, providing long-term beauty with minimal effort. It’s also known for being drought-tolerant once established, making it a good choice for gardeners looking to reduce water usage.

Key Characteristics of Dwarf Fountain Grass

Before diving into the details of how to grow and care for Dwarf Fountain Grass, let’s take a look at some of its key characteristics that make it so popular among gardeners:

1. Compact Size

As its name suggests, Dwarf Fountain Grass is a smaller variety of fountain grass. It typically reaches a mature height of around 2 feet, with a similar width, making it perfect for small spaces and garden borders. This compact size also makes it suitable for container gardening.

2. Fountain-Like Growth Habit

One of the most appealing features of Dwarf Fountain Grass is its arching, fountain-like growth habit. The leaves grow outward and then curve downward, creating a graceful, flowing effect that adds movement and texture to the landscape.

3. Attractive Flower Spikes

In late summer to early fall, Dwarf Fountain Grass produces showy, bottlebrush-like flower spikes that rise above the foliage. These flower spikes start out in shades of green or pinkish-purple and mature to a soft, tan or brown color. The flowers are a striking feature that adds visual interest to the garden and can be enjoyed for their beauty well into the fall.

4. Color and Texture

The foliage of Dwarf Fountain Grass is a rich green color during the growing season and transitions to a golden brown or tan in the fall. The fine-textured leaves create a soft, feathery look, and the movement of the grass in the wind adds an element of tranquility to the garden.

5. Drought Tolerant

Once established, Dwarf Fountain Grass is quite drought-tolerant, making it an excellent choice for xeriscaping or for gardens in areas with water restrictions. It can handle dry conditions better than many other ornamental grasses, although it still benefits from occasional watering in very hot or dry periods.

6. Low Maintenance

Dwarf Fountain Grass is a relatively low-maintenance plant. It doesn’t require frequent pruning or fertilizing, and it is generally pest- and disease-free. This makes it a great option for gardeners who want a beautiful plant without a lot of upkeep.

7. Cold Hardy

Dwarf Fountain Grass is hardy in USDA zones 5 through 9, meaning it can withstand cold winters in many regions without any special care. In colder zones, the grass may die back in the winter but will regrow in the spring.

Popular Varieties of Dwarf Fountain Grass

There are several varieties of Dwarf Fountain Grass, each with its own unique characteristics. Here are some of the most popular ones:

1. Pennisetum alopecuroides ‘Hameln’

‘Hameln’ is one of the most widely grown varieties of Dwarf Fountain Grass. It features compact growth, reaching about 2 feet in height, and produces cream-colored flower spikes in late summer. Its neat, mounding form and fine-textured foliage make it an excellent choice for borders and small garden spaces.

2. Pennisetum alopecuroides ‘Little Bunny’

‘Little Bunny’ is an even smaller variety, reaching only about 12 to 18 inches in height. This makes it ideal for container gardening or for the front of garden beds. Its fluffy, white flower spikes are a charming addition to any landscape, and its compact size makes it perfect for tight spaces.

3. Pennisetum alopecuroides ‘Cassian’

‘Cassian’ is another compact variety of Dwarf Fountain Grass, growing to about 2 to 3 feet tall. It produces golden-brown flower spikes in late summer and has a more upright growth habit compared to other varieties. Its foliage turns a beautiful golden color in the fall, making it a great choice for autumn landscapes.

4. Pennisetum setaceum ‘Rubrum’

‘Rubrum’, commonly known as Red Fountain Grass, is a variety with striking burgundy or reddish-purple foliage. While it is not cold hardy in all regions and is often grown as an annual in cooler climates, it makes a stunning addition to gardens with its bold color. It can grow up to 3 feet tall, and its reddish flower spikes add extra drama to the landscape.

How to Plant Dwarf Fountain Grass

Planting Dwarf Fountain Grass is relatively straightforward, and with the right preparation, you can enjoy its beauty for many years to come. Here’s a step-by-step guide to planting Dwarf Fountain Grass in your garden.

1. Choose the Right Location

Dwarf Fountain Grass thrives in full sun, so choose a spot in your garden that receives at least 6 hours of direct sunlight per day. While it can tolerate partial shade, too much shade can cause the plant to become leggy and produce fewer flowers.

Make sure the location has well-drained soil. Dwarf Fountain Grass can tolerate a wide range of soil types, but it prefers soil that drains well. Avoid planting it in areas where the soil tends to stay waterlogged, as this can lead to root rot.

2. Prepare the Soil

Before planting, it’s a good idea to amend the soil with compost or other organic matter to improve its texture and fertility. This will help the grass establish itself more quickly and encourage healthy growth.

Loosen the soil to a depth of about 12 to 18 inches, and mix in compost or aged manure if the soil is poor or compacted. If your soil is heavy clay, consider adding sand or other amendments to improve drainage.

3. Planting

To plant Dwarf Fountain Grass, dig a hole that is about twice the width of the root ball and the same depth. Gently remove the plant from its container and loosen the roots if they are tightly packed. Place the plant in the hole, making sure that the top of the root ball is level with the surrounding soil.

Backfill the hole with soil, gently firming it around the roots to eliminate any air pockets. Water the plant thoroughly after planting to help it settle in and establish its roots.

4. Spacing

If you are planting multiple Dwarf Fountain Grass plants, space them about 2 to 3 feet apart, depending on the variety. This will give them enough room to spread and grow without overcrowding.

5. Watering

Water the newly planted grass deeply to help it establish its root system. After that, Dwarf Fountain Grass is fairly drought-tolerant and only needs occasional watering during dry spells. Be careful not to overwater, as this can lead to root rot.

6. Mulching

Applying a layer of mulch around the base of the plant can help retain moisture, suppress weeds, and regulate soil temperature. Use a 2- to 3-inch layer of mulch, but avoid piling it directly against the stems of the plant, as this can cause rot.

Caring for Dwarf Fountain Grass

Once established, Dwarf Fountain Grass is a low-maintenance plant that requires minimal care. However, there are a few simple tasks you can perform to keep your grass looking its best throughout the year.

1. Watering

While Dwarf Fountain Grass is drought-tolerant, it does benefit from regular watering, especially during prolonged periods of dry weather. During the first growing season, make sure to water your newly planted grass regularly to help it establish its root system.

Once established, you can reduce the frequency of watering, but make sure the soil doesn’t dry out completely during hot or dry periods. It’s best to water deeply, allowing the moisture to reach the roots, rather than frequent shallow watering.

2. Fertilizing

Dwarf Fountain Grass doesn’t require heavy fertilization, but an annual application of a balanced, slow-release fertilizer can help promote healthy growth and flowering. You can apply fertilizer in the spring, just as new growth begins to emerge. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.

3. Pruning and Deadheading

Dwarf Fountain Grass does not require regular pruning, but cutting back the foliage in late winter or early spring before new growth begins is recommended. This will remove the dead, brown foliage from the previous season and allow the fresh green growth to emerge.

To prune, simply cut the grass back to about 3 to 6 inches above the ground. Use sharp pruning shears or hedge trimmers to make clean cuts. This process helps rejuvenate the plant and keeps it looking tidy.

You can also remove the flower spikes after they have finished blooming, although many gardeners leave them on the plant for winter interest. The dried flower spikes can add texture and beauty to the garden during the colder months.

4. Pests and Diseases

Dwarf Fountain Grass is relatively pest- and disease-free, making it a trouble-free choice for most gardens. However, it’s still a good idea to keep an eye out for any potential issues. Aphids, spider mites, or other pests can occasionally become a problem, but they are usually easy to control with insecticidal soap or by introducing beneficial insects like ladybugs.

In terms of diseases, the most common issue is root rot, which can occur if the plant is overwatered or planted in poorly draining soil. To prevent root rot, make sure the soil is well-draining and avoid overwatering.

5. Winter Care

Dwarf Fountain Grass is hardy in USDA zones 5 through 9, meaning it can withstand cold winters without much trouble. In colder climates, the grass may die back to the ground during the winter months, but it will regrow in the spring.

To protect the plant during harsh winters, you can apply a layer of mulch around the base to insulate the roots. In regions with particularly cold winters, you may also want to leave the dead foliage on the plant through the winter and cut it back in the spring.

Creative Landscaping Ideas with Dwarf Fountain Grass

Dwarf Fountain Grass is incredibly versatile and can be used in a variety of ways in the landscape. Here are some creative ideas for incorporating this ornamental grass into your garden design:

1. Borders and Edging

Dwarf Fountain Grass makes an excellent border plant due to its compact size and neat, rounded form. Plant it along pathways, garden beds, or driveways to create a soft, natural edge. The arching foliage and graceful flower spikes will add texture and movement to your garden borders.

2. Mass Planting

For a dramatic effect, consider mass planting Dwarf Fountain Grass in large drifts or clusters. This works especially well in larger garden beds or open spaces where you want to create a sense of flow and movement. The soft, feathery foliage of the grass will catch the light and sway in the breeze, creating a beautiful, dynamic display.

3. Mixed Perennial Beds

Dwarf Fountain Grass pairs well with other perennials, making it a great addition to mixed flower beds. Combine it with plants that have contrasting foliage or flower colors, such as purple coneflowers, black-eyed Susans, or Russian sage, to create a visually interesting and balanced garden design.

4. Container Gardens

Due to its compact size, Dwarf Fountain Grass is also an excellent choice for container gardening. Use it as a centerpiece in large pots or combine it with other plants in mixed containers. The grass’s arching form and fine texture will add height and interest to your container arrangements.

5. Water Features

Dwarf Fountain Grass looks stunning when planted near water features such as ponds, fountains, or garden streams. The soft, flowing foliage of the grass complements the movement of the water, creating a peaceful and harmonious atmosphere. Additionally, the reflection of the grass in the water can add depth and beauty to the overall landscape.

6. Winter Interest

One of the great things about Dwarf Fountain Grass is that it can provide visual interest even in the winter months. The dried flower spikes and tan foliage can add texture and structure to the garden when most other plants have died back. Consider leaving the grass standing through the winter and enjoying its sculptural form in the snowy landscape.
