Wildflower plug plant selection for biosolar roofs
Have you ever thought of combining a green roof with solar panels? There are lots of things to like about this arrangement, not least the variety of plants you can grow. Depending on where they are positioned - under or in front of the panels - you can grow sun or shade loving species, which will get more or less moisture depending on whether they're directly under the panels or under their leading edges.
We offer trays with 13 different species, including shade and sun loving plants, selected from the list below. If you'd like something different just let us know.
Kidney Vetch, Common Knapweed, Viper's Bugloss, Lady's Bedstraw, Perforate St John's-wort, Field Scabious, Autumn Hawkbit, Rough Hawkbit, Common Toadflax, Bird's-foot-trefoil, Musk-mallow, Wild Marjoram, Hoary Plantain, Salad Burnett, Meadow Buttercup, Biting Stonecrop.
Shade / Part Shade:
Agrimony, Lords and Ladies, Wood Avens, Cowslip, Selfheal, Red Campion, Bladder Campion, Tufted Vetch, Common Dog Violet.One tray costs £75, and two or more are £70 each, meaning these small (55cc) native wildflower plug plants work out at 52p/plant before VAT and delivery. These plants come in 6cm deep mixed trays of 104, meaning they are a perfect size for inserting directly into green roof planting medium. Our consultants recommend a higher concentration than for normal planting , so reckon on planting 10 - 16 per square metre. If you buy multiple trays we will endeavour to include as many species as possible from the list. We also supply an appropriate wildflower seed mixture. These native British plants aren't just attractive and good sources of nectar, but they're also essential foodplants for butterfly and moth larvae.
We recommend a consultant who can design, supply and fit a wide variety of green roofs to suit your requirements. Contact us for further details.
All these plants are grown from guaranteed native seed, most of which is collected by the suppliers themselves. They're grown without the use of peat, fungicides or pesticides.
We donate half of our profit on sales of this selection of native British wild flower plugs to Butterfly Conservation
