Lindum Wildflower Mat

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

Working with the University of Sheffield’s Professor Nigel Dunnett and the Green Roof Centre, Lindum has developed the Wildflower Mat. Attractive to pollinators, it provides a biodiverse and colourful range of wildflowers, herbs and flowering perennials that will flourish in the conditions created on many types of green roofs.

Why choose Lindum Wildflower Mat?

Features: An attractive mixture of wildflowers, herbs and flowering perennials to produce a biodiverse and colourful alternative to traditional sedum, with a prolonged flowering period, from April – September. The flowering height ranges from 30 – 100cm depending on the substrate depth and maintenance regime.

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

Mixture: The mixture is designed to have a range of plants that flower April – September, which have visual appeal and provide an excellent habitat for wildlife.

As well as a range of wildflowers including Lady’s Bedstraw, Cats Ear and Yellow Chamomile, herbs such as Wild Majoram and Thyme, and pink flowering perennials such as Dianthus are part of the colourful mix.

Maintenance: 1-2 cuts per year at the end of the flowering period, removing all cuttings from the roof.

Through dry/warm periods of time the roof will need a help in hand so it must be watered manually or by a watering system.
