Clarke & Clarke Secret Garden Leiden Teal/Berry FabricClarke & Clarke Secret Garden Leiden Teal Berry Fabric. Leiden is a mid scale print that evokes a folk style in the drawing of these beautiful botanicals, a nod to it's namesake, The Hortus botanicus Leiden, the oldest botanical garden in The Netherlands. This is a modern take on an old world design where the spacing of each flower and plant gives way to a soft ground with some pastel notes. * Available in 5 colourways * Fabric Collection: Secret
