A spiral of colour is the theme top designer Tom Massey has taken on in his latest show garden which displays the way gardens can enhance your mood and help your wellbeing.

Research shows the therapeutic value and feeling of wellbeing that people get from gardening, according to Thrive, the charity that uses gardening to help people living with disabilities or ill health, or are vulnerable or isolated. But colour can also make an impact.

Tom told us exactly what colours to plant.

1. Red

"Red is a very stimulating colour - it's eye-catching, it can mean passion, danger and warning, but ultimately it's an exciting colour," says Massey, who uses Sanguisorba 'Tanna', Crocosmia 'Hellfire' and Panicum virgatum 'Shenandoah' to energise and uplift in his own show garden.

"Red comes to the fore if you want a vibrant bed."

2. Orange

Orange hues spark enthusiasm, fascination, happiness and creativity, combining the energy of red and the happiness of yellow.

If you prefer an orange palette, you might try Achillea millefolium 'Terracotta' and Kniphofia uvaria 'Nobilis'.

3. Yellow

Yellow is the colour of sunshine, associated with joy, happiness and intellect and produces a warming effect, arousing cheerfulness and stimulating mental activity, says Massey.

It's an optimistic, positive colour and plants in this band include Helianthus annuus and Inula helenium.

4. Purple

Purple is associated with wisdom and dignity. Plants in this band include Veronicastrum virginicum 'Fascination' and Miscanthus 'Purpurascens'. Lilac and lavender shades also have a restful quality.

5. Blue

Blue is often associated with depth and stability, symbolising trust, loyalty, wisdom, confidence and calm. Plants in this band include Panicum virgatum 'Heavy Metal' and Phlox 'Blue Paradise'.

6. Greens

Bright colours tend to look more vibrant in sunny settings, while blue and green palettes can flourish in semi-shaded areas, creating a cool, calm atmosphere.

At the centre of Massey's garden, is the screen of towering bamboo.

The colour palette is pure green, the colour of nature, representing growth, harmony, freshness, stability and endurance.

Green has healing power, it is the most restful colour for the human eye and it has strong emotional correspondence with safety and sanctuary.
