WHAT ARE THRILLERS, FILLERS AND SPILLERS? 
Simply put, thrillers, fillers and spillers are plants you can put in a container that have different heights and textures. Using a mixture of these three plants creates a fuller looking container that has everything you’re looking for in a garden display, which is dimension, height and colour 
When choosing your plants, make sure you pick colours that suit your container and other flower displays. The colours you choose entirely depends on your personal tastes, but usually one or two shades of complementary colours looks best – for example, purple and pink 
Thrillers 
These are your tallest, most impressive plants that go at the back of your container. These are usually flowers, but in larger pots could also be trees or shrubs. Examples of thriller plants are: 
Hydrangea 
Geranium 
Snapdragon 
Canna lillies 
Fillers 
Fillers are your bushy and bright plants used to close or fill any gaps in your container where soil is still showing. Planted in the middle, these will have the most colour and texture. Fillers should complement your thriller plants and pull the look together. Some good filler plants to include in your planters are:  
Hostas 
Petunia 
Cosmos 
Eucalyptus 
Spillers 
As the name suggests, spillers are plants that hang over the sides on the container, or ‘spill’ over the edge. Their purpose is to add gorgeous cascading foliage and texture, as well as colour and visual interest, to the overall look of the pot. Spiller plants can be: 
Ivy 
Fern 
Creeping jenny 
Dichondra ‘silver falls’
Our gardening expert’s top tip: When choosing the plants for your container make sure they have similar care requirements, like the amount of water and sunlight they need, so they’ll all work well together when planted

Your choice of thriller, filler and spiller plants 
In our container, we've chosen Hydrangea as our thriller because it’s our plant of the month, and we love the large, showy flowers and how it comes in various colours. We’ve also picked Heuchera as our filler and mini ivy for the spiller since it creates a lovely trail - but remember you can pick anything that suits your personal style
