Thriller, Filler and Spiller

How To Create Fabulous Containers

Container gardening is a brilliant way to add life, colour and texture to any outdoor (or indoor) space. With just a pot and a touch of creativity, you can craft show-stopping planters that elevate your garden, patio or balcony. One design principle that has revolutionised how we approach planters is the captivating concept of “thriller, filler and spiller.”

Fabulous planters A world of possibility

Containers can transform any area from mundane to marvellous. Whether your space is an expansive garden or a bijou balcony, the right planter can work wonders. What makes them special? Think compact bursts of creativity capable of reflecting your personal style.

Containers can instantly add height and drama, soften hardscapes and turn hard-to-plant areas into focal points of beauty. These portable displays also make gardening accessible to everyone, accommodating varying levels of skill, mobility and space. Plus, they offer the flexibility to mix, match or relocate as needed.

Planting up planters Where to begin?

Starting a container garden might seem daunting at first, but all it takes is a little preparation and creativity. Think of the process like storytelling. Your plants are the characters, the container is the stage, and together, they create a dazzling narrative of seasonal charm and beauty.

Considerations for your containers

Before planting, consider the following essential factors:

  • Colours

Will you bring a fiery burst with oranges, reds and yellows? Or will softer tones of whites, blues and greens suit your mood? Choose colours that complement your space and create the vibe you love.

  • Scent

Why limit your planters to visual appeal? Add floral fragrances such as lavender or scented geraniums for a multisensory delight.

  • Contrasting Colours and Textures

Juxtaposing contrasting foliage and flowers creates visual interest. Combine the lush softness of silver-green lamb’s ear with bold, structured succulents, for example.

The thriller, filler, spiller method

Now for the fun part! The “thriller, filler, spiller” formula is all about creating balance, movement and drama in your container design. The idea is:

  1. Thriller (Height and Drama)

The thriller is your statement plant – the star of the show. This is typically placed at the centre in a round container or the back of a rectangular one. Choose a plant with height and architectural interest to draw the eye.

Examples include:

– Spiky grasses like Cordyline or Phormium.

– Bold and bright Canna Lilies.

– Ornamental grasses like Pennisetum.

  1. Filler (Bulk and Texture)

Your filler will complement the thriller, adding texture and volume at mid-height. These plants help blend the composition and keep it looking lush.

Popular filler choices:

– Petunias for colour.

– Heuchera for foliage variety.

– Nemesia for delicate flowers.

  1. Spiller (Trailing Elegance)

The spiller cascades over the edge of the container, creating a sense of flow and abundance. It softens the container and adds a touch of magic.

Good spiller ideas:

– Trailing ivy or sweet potato vine.

– Lobelia for soft, flowing beauty.

– Bacopa for delicate floral cascades.

Choosing the right plants Position matters

Planters aren’t just about looks; their placement significantly influences plant selection. Is your planter destined for a sun-drenched patio, or will it sit in a shaded corner of the garden? Light requirements vary between plants, and matching them to a location will save you disappointment.

Consider factors like wind exposure and heat retention, too, especially for containers in urban or roof garden environments. Hardy plants may be necessary for exposed locations, while shyer species might require a gentler microclimate.

Considering container aesthetics Style counts

The colour, shape and material of your container play a huge role in creating your desired aesthetic.

  • Colour

A terracotta pot complements a warm-toned arrangement beautifully, while contemporary black or grey containers suit sleek modern aesthetics.

  • Material

Ceramic pots retain moisture well but are heavier, while plastic containers are lightweight and affordable. Metal planters offer a modern feel but can heat up quickly.

  • Shape

Square, round or abstract shapes all bring unique focal points to your space. Pick something that complements your overall garden style or decor.

Styling for themes and seasons

Take your containers to the next level by curating them for a specific theme or season. A pastel-themed planter with pastel geraniums and dusty miller can evoke spring perfection; meanwhile, deep reds and oranges paired with trailing ivy are perfect for autumn warmth.

Caring for your beautifully crafted planter Give your plants the best

Once you’ve set up your stunning container, it’s important to care for it properly. Here’s how to keep your plants thriving:

  1. Perfect Watering

Containers dry out more quickly than garden beds, especially in sunny locations. Regular, consistent watering is key—but make sure not to overdo it. Check the soil; water when the top inch feels dry to the touch.

  1. Deadheading and Pruning

Remove spent blooms to encourage more flowers and keep your planter looking fresh. Trim back any leggy growth to maintain a neat appearance.

  1. Drainage and Feeding

Ensuring proper drainage is critical. Always use pots with drainage holes and add a layer of grit or gravel at the bottom. Feed your plants with a balanced fertiliser to sustain steady growth.

Create your show-stopping display

With the thriller, filler and spiller method, you can craft stunning container displays brimming with personality, vibrance and life. Every planter you create is a reflection of your creativity and a brightened corner for all to enjoy.

Now, gather your pots, get those gloves on, and start planting! Remember, gardening is as much about the joy of creation as it is about the plants themselves.

The Ultimate Guide on How to Choose Garden Planters

Gardening is an enriching experience that provides a sense of fulfilment from nurturing the earth and watching your plants grow. One essential aspect of gardening is choosing the appropriate planters for your plants. Picking the right garden planter is as crucial as selecting the right plant, as it impacts their growth and overall appearance. In this guide, we’ll explore the factors you should consider when choosing a garden planter that suits your needs and complements your garden design.

Material – The first key factor to consider when choosing a garden planter is the material. Garden planters are made of various materials, such as terracotta, metal, wood, plastic and stone. Each of these materials comes with different advantages and disadvantages. Terracotta planters are decorative and ideal for plants that require good drainage. Metal planters, on the other hand, are durable, lightweight, and available in various colours. Wooden planters can fit in well with natural garden settings and are lightweight, but they can be susceptible to rot. Plastic Planters are budget-friendly, lightweight, and come in different colours and sizes, but they can easily crack in hot weather conditions. Stone planters are a stylish addition to any garden; they are weather-resistant, but the weight might be difficult to move.

Size – Plant roots need sufficient space to grow, and so, it’s essential to consider the size of your garden planter. You don’t want to choose a container that’s too small and stifles growth or too big, it becomes an obstruction. The size will depend on the type of plant you intend to grow and the space which you have. For large shrubs, trees or vegetable gardens, you will need a planter with a large capacity, preferably more than 60cm in diameter. For small flowers and herbs, you can opt for smaller planters. It’s important to note that the size of the pot should be proportional to the overall size and type of plant being grown.

Drainage – Plants require good drainage to survive and thrive. Therefore, a good garden planter should have efficient drainage holes to allow excess water to drain away. Poor drainage results in root rot and stunted plant growth. A small hole will not allow proper drainage, while oversized holes will cause soil to leak out. Self-watering planters are also a good consideration; they have built-in reservoirs that hold water, as well as providing air for the roots to breathe.

Style – Garden planters come in different colours, shapes, and designs. It’s essential to choose a planter that compliments your garden’s style and the overall landscape. If your garden has a traditional style, you could opt for a terracotta or wooden planter. A contemporary garden design may benefit from sleek metal or stone planters, while ornamental planters can bring charm, character and interest to your garden.

Cost – The price of a garden planter is essential to consider. It’s essential to determine how much you’re willing to spend. A cheaper planter won’t last long, but you don’t have to break the bank to get a quality and long-lasting planter. The type and size of the planter you choose will also affect the cost. The price will vary depending on the material and the design of the planter.

Choosing the right garden planter can transform and elevate the look of your garden, while also supporting the health of your plants. You need to consider crucial factors, such as the material, size, drainage, style, and cost, to select a planter that’ll enhance your garden. With the right planter, your garden can be a haven of relaxation and beauty. Get creative and let your garden bloom.
