Best Plants for Raised Beds

Have you heard of the benefits or planting in raised ornamental garden beds, but you’re wondering “what can I plant here that will thrive in the conditions and look amazing?” Then, you’ve come to the right place because that’s exactly what you’ll learn in this article.

A raised bed is an elevated garden usually filled with some type of mixture of potting mix, soil and compost, often contained within a wooden, metal, or stone frame. This method of gardening offers distinct growing environments compared to traditional in-ground planting.

First of all, we’ll go over some of the basic growing conditions common in raised planter beds, some of the pros and cons of using raised beds, and then we’ll go over a list of some amazing plants that will suit the space – including screens, small shrubs, ground covers and strappy plants. You’ll notice a clear focus on native Australian plants with a few exotics sprinkled throughout.

Best Plants for Raised Beds

These raised beds allow plants to cascade over the sides, and have a strong colour palette of greens, yellows and oranges. https://www.shutterstock.com/image-photo/artistic-street-decorations-raised-rectangular-flower-1500212861

Growing Environments for a Raised Bed

Soil Quality and Composition

  • Controlled Soil Quality: Raised beds allow gardeners to precisely control the soil quality, which can be manipulated to suit the needs of particular plants by combining optimal amounts of compost, fertiliser, and well-drained soil. This is especially beneficial in gardens with poor soil.
  • Improved Drainage: The elevated nature of raised beds ensures better drainage, reducing the risk of waterlogging and root rot.

Sunlight and Temperature

  • Enhanced Warmth: The soil in raised beds tends to warm up more quickly in the spring compared to the ground, allowing for earlier planting.
  • Increased Sunlight Exposure: Raised beds can be positioned to maximise exposure to sunlight, crucial for photosynthesis and plant growth.

Weed and Pest Control

  • Reduced Weed Growth: The controlled environment of a raised bed can reduce the invasion of weeds, making maintenance easier.
  • Pest Management: Elevated beds can be less accessible to some ground-dwelling pests, though they may attract others.

Benefits of Raised Beds

  • Soil Customisation: Allows for precise tailoring of soil conditions to meet plant needs.
  • Better Drainage: Reduces risks associated with poor drainage.
  • Extended Growing Season: Warmer soil extends the growing season.
  • Ease of Access: Easier to manage without bending, ideal for individuals with mobility issues and people in wheelchairs.
  • Aesthetic Appeal: Can enhance the visual appeal of a garden space.

Drawbacks of Raised Beds

  • Initial Cost: The construction of raised beds can be costly, requiring materials and soil.
  • Watering Needs: Raised beds may dry out more quickly, necessitating more frequent watering.
  • Limited Space: The confined area of raised beds can restrict the growth of larger plants and trees.
  • Tough Growing Conditions: Without irrigation, the excess drainage and heat can scorch some plants and can commonly lead to premature plant death.

Plant Characteristics for Thriving in Raised Beds

  1. Compact Root Systems: Plants with shallow or compact root systems are ideal as the depth of soil is limited.
  2. High Water Efficiency: Drought-resistant or water-efficient plants perform well due to the potential for quicker soil drying.
  3. Soil Preference: Plants that thrive in well-drained, rich soil benefit from the customised soil mix of raised beds.
  4. Sunlight Tolerance: Sun-loving plants that require full sun can be positioned optimally for maximum light exposure. Obviously, a planter box in the shade won’t get as hot, dry, or sunny as a planter box in full sun.

Styling Planter Boxes for Optimal Space Utilisation

Styling planter boxes effectively can transform an urban space, garden or patio, making the best use of available space while creating an aesthetically pleasing environment. By considering factors such as colour, texture, form, shapes, and layers, you can design planter boxes that not only maximise space but also enhance the visual appeal of your outdoor area.

Colour

Selecting a cohesive colour palette for both the plants and the containers can create a harmonious look. You might opt for vibrant, contrasting colours to make a bold statement, or choose muted, complementary tones for a more subdued, elegant appearance. Additionally, consider the colour of the planter boxes themselves: neutral shades like grey, black, or white can provide a modern backdrop, allowing the plants’ colours to pop, while brightly coloured boxes can inject energy and personality into the space. Warm colours like red, orange and yellow excite the passions, while cool colours like blue, green and purple can calm the passions.

Texture

Texture adds depth and interest to planter boxes. Combining plants with varying textures—such as the coarse leaves of succulents, the needle-like leaves of westringia, and the smooth surfaces of glossy lilly pilly leaves—creates a dynamic visual effect. The planter box material also contributes to the overall texture. Wooden boxes offer a rustic charm, metal ones add contemporary sleekness, and ceramic containers can provide a touch of traditional elegance. Mixing different textures within the same planter or amongst several planters can result in a more engaging and layered design.

Form and Shape

The form and shape of the plants and planter boxes significantly impact the overall aesthetic and functionality of the space. Tall, upright plants can add height and structure, while trailing varieties soften edges and create a cascading effect. Similarly, mixing different shapes of planter boxes—rectangular, square, round, and troughs—can break the monotony and add visual interest. Grouping plants with different forms together helps to balance the composition and ensures that no single element dominates the space.

Layers

Creating layers within planter boxes helps make the most of vertical and horizontal space. Layering involves arranging plants at varying heights and depths to create a sense of fullness and dimension. Start with taller plants at the back or centre (depending on where people will view it from) and gradually move to shorter plants at the front or edges. This tiered approach ensures that all plants receive adequate light and are visible, contributing to a lush, well-organised display. Don’t forget the ground-covering plants which can be a lot more exciting than relying on mulch to cover the surface. And embrace the cascading appearance of trailing and strappy plants, which blur the edges of a raised bed beautifully.

Using Vertical Space

Incorporating vertical elements can maximise limited space, especially in small gardens or patios. Consider using tiered planters, columnar shrubs, climbers, hanging baskets, and/or wall-mounted planters to elevate some of your greenery. Vertical gardening not only saves floor space but can also create striking visual points and make the area feel more expansive.

Grouping and Spacing

Effective use of space also involves strategic grouping and spacing of planter boxes. Clustering several planters of varying sizes and shapes can create a focal point and add complexity to the design. Ensure there’s enough space between planters for easy maintenance and to prevent overcrowding, which can impede plant growth and health. Thoughtful spacing allows each plant to thrive and the arrangement to look intentional and well-considered. Plant labels should give you info on a plant’s mature size – otherwise, search for this info online. Remember that different cultivated varieties within the same species can differ drastically in their growth habits.

Seasonal Considerations

Styling planter boxes should also take into account seasonal variations. Plan for seasonal rotation by choosing plants that can be easily swapped as the weather changes, or choose plants that flower or add interest synergistically throughout the year. This keeps the display fresh and vibrant year-round. Incorporate evergreens or perennial plants as the backbone of your design, supplemented by seasonal annuals for bursts of colour and variety.
