Individually planted extensive green roof

When to specify...

Individual Plug Plants are used when the client wishes to choose a particular type and species of vegetation. The 'plugs' are varieties of sedums, grasses, herbs and perennials and are planted by hand to the required density. The more plugs per square metre, the faster the vegetation will establish to cover the roof entirely.
