• When beginning to work with colour, start with just two—yellow and orange, for example—and make small groupings, repeating both hues and plant shapes.
• When pairing flowering and foliage plants, don’t assume every green leaf will work effectively with every flower colour. For example, a purple bloom will stand out against chartreuse foliage, but will disappear against a darker, duller leaf.
• Pay attention to foliage, which always dominates the border. Look for patterns and colours in the leaves and echo them in nearby plants. For example, match the purple-red splotch in the centre of ‘Sunspot’ heucherella with a flower of the same colour.
• Study how colour works in the natural landscape and mimic these effects in your garden. White separates colours from one another, emphasizing other plants.
Blue in the background makes a space look larger, while yellow lights up dark corners; keep in mind that red and purple are harder to see from
• Use colour to evoke emotion. For example, light shades create a feeling of openness; dark ones, on the other hand, are more theatrical.
• Don’t be afraid to combine vegetables with ornamentals to create strong contrasts.
