A mixture of wildflowers, sedums, herbs and flowering perennials, specifically designed for green roofs and sustainably grown in the UK.

Working closely with the University of Sheffield’s Dr Nigel Dunnett and the Green Roof Centre, developing the Wildflower & Sedum Mat to provide a biodiverse, colourful and drought tolerant range of wildflowers, sedums, herbs and flowering perennials that will flourish in the conditions created on many types of green roof.

Features: An attractive mixture of drought tolerant wildflowers, herbs, sedums and flowering perennials to produce a biodiverse and colourful alternative to traditional sedum, with a prolonged flowering period, from April to September. Flowering height is 20-30cm.

Benefits and uses: As an alternative to pure sedum it combines the drought tolerant aspects of sedums with the colour and ecological benefits of wildflowers and other species, attracting a wider range of birds, bees, butterflies and invertebrates.

Mixture: The mixture is designed to have a range of plants that flower from April to September, which have visual appeal and provide an excellent habitat for wildlife. As well as a range of wildflowers including Oxeye Daisy, Lady’s Bedstraw, Cats Ear and Yellow Camomile, three sedum varieties are included, and herbs such as Wild Marjoram and Thyme, and pink flowering perennials like Dianthus are part of the colourful mix.

Maintenance: One light cut in late autumn removing all cuttings.
