A blue and purple border, cool and restful.
Blues and purples are the most restful colours in the garden – they recede, cool the eye, and make a space feel bigger and calmer. A blue and purple border, lifted with silver and the odd spark of contrast, is one of the most sophisticated schemes you can plant.

How to build a blue and purple scheme
Blues and purples work because they are 'cool' colours – they sit back, calm the eye and make a border feel deep and serene. But a scheme of blues alone can read flat, so the trick is variety within the range: true blues, violet-purples, lavender and mauve, plus plenty of silver foliage to lift them and stop them muddying together.
A single spark of contrast makes the whole thing sing – a touch of soft yellow or apricot, or a little white, catches the eye and makes the blues look even bluer. Used sparingly, that one accent is what turns a nice border into a memorable one.

How does the AI garden design work?
Upload a photo of your garden or a single border, and tell us what you'd like: refresh your borders, keeping your garden's shape, or redesign the whole space with new layout, paths and planting. Pick a style, and we generate a photorealistic redesign of your actual garden. When you love one, unlock its planting plan – every plant, how big each grows, and where each goes.
Are the plants real – can I actually buy and plant them?
Yes. Every design can become a planting plan of real, available UK plants, with each plant's mature height and spread, where it goes and a month-by-month flowering guide. The plans are built on real horticultural data and shaped by a professional gardener – not generic AI guesses – so the garden in the picture is a garden you can genuinely plant.
Is it really free, and what does it cost after?
Yes, you get 3 free designs every day, straight away. Free designs carry a small watermark. If you want more designs, higher quality and clean images that are yours to keep, a one-off Fresh Look starts at £19 and covers your whole project. The £9 Design Pack is a separate one-off that gives any single design its clean image and full plant list, only if you want to make it real.
What colour goes best with blue and purple in a border?
Silver foliage lifts and links them, while a small amount of soft yellow, apricot or white makes a striking accent – the warm contrast makes the cool blues look richer. Keep the accent sparing so the scheme stays calm.
