This is a Chelsea Flower show garden by Cleve West, back in 2008. The curving paths are made with Vande Moortel pavers www.vandemoortel.co.uk They are small narrow pavers, like vintage bricks, and they lend themselves to both traditional and contemporary gardens.
The planting here is very pretty. However I notice the centrepiece in this border is a silver Astelia – very striking and architectural but sadly not hardy in our British weather. An alternative could be a silver leaved Artemesia, excellent for setting off those mauves and deep purple irises. The splash of orange (looks like geums) adds some interest to the scheme. I also like the lemon yellow spikes provided by Tellima grandiflora.
