Wildflowers

The wild flowers of Inis Meain
image025.jpg
What better way to roof a house than with a carpet of exotic  wildflowers grown on Inis Meain interspersed with sedum?
 That's what occured to us as we dreamt up an environmentally friendly way of re-roofing an old farm shed that is being painstakingly restored.

The curse of modern farming techniques - herbicides, pesticides, deep plough tractors, ripped up hedgerows, are alien to Inis Meain,
several several hundred varieties of wildflowers flourish here.  Here on the most isolated of the Aran Islands, you can wander for hours among stone walls built by hand over centuries and be astonished by the array of wild flowers all around you.

They include Spring Gentian, Pyramidal Bugle, Dense-Flowered Orchid, Irish and Mossy Saxifrages, Purple Milk Vetch, Bird's Foot Trefoil, Mountain Pansy. All shades of Thrift, Bloody Cranesbill, Common Butterworth, marsh orchids, Mountain Everlasting, Ladies Mantle, Long stalked Cranesbill, wild Thyme, Field Gentian, stone Bramble, Spleenworts, Harts-0tongue, Rusty-back.

Along the north coast a long sandy beach contains sea rocket, se bindweed, sea holly and sea spurge. Ray's Knotgrass and Rock Samphine covers many rock faces.

In high summer the upper fields are a riot of Oxeye Daisy, Knapweed, Carline Thistle, Devil's Bit and Harebells along with Frog Orchids and Common Ladies Tresses.

There are many many more plants
in this botanical paradise, some yet to be charted. What makes the island so rich in flora is that the Arans are a continuation of the limestone of the Burren, Co Clare. The little soil there is is rich and well drained and the rock keeps the land warm through then winter.

Look at a typical gryke and you might see a Mediterranean plant - the maidenhair fern for example - living within six inches of a plant more commonly found in alpine locations such as the bloody cranesbill.

We want to preserve all this biodiversity and so to the new roof.



Our cottage is a traditional rye thatched dwelling
The thatch is formed from individual handfulls or dornans of straw . its a skilled and labour intensive process which sadly is dying out all over Ireland. Inis Meain is one of the last redoubts of skilled thatchers and Synge's cottage (below) was recently restored with a full traditional rye thatch.

We have watched the tin roof on an outlying shed deteriorate over the years and finally decided to turn it into a wilflife friendly living green roof planted Inis Meain wild flowers and plants. The outhouse is being sympathetically restored in the vernacular style by our neighbour Sean Faherty a gifted stone mason and all round craftsman.

This is the modest outhouse (where a family lived in the 1960s) and which is destined to have a living wildflower roof and walls insulated with hemp and lime sometime later this year.

June 2009:
The Wildlife Roof and Hemp wall shed starts to take shape
Our neighbour Sean has been restoring this small outbuilding to the main cottage over the winter. The idea is to build a state of the art green building, complete with a living roof of Inis Meain wild flowers. But first Sean has had to raise the walls and install hefty rafters to take the weight of the sod roof. A plywood covering is in place awaiting delivery of a special waterproof membrane from Northern Ireland.

A Green Roof .....New England Style



ReNatur_Norwegian_House.jpgnorway040s.jpgNewEnglandroof.jpeg

The American Orchid Society began as a green roof club.   American women on the Great Plains in the 1860's, mostly German, conducted contests called 'Das Schoenste Orchideenhaus,' in which women competed with displays of native buffalo orchids (now extinct due to the demise of bison wallows which was their only habitat), various fringed orchids, and other choice native plants.  

The recent lack of green roofs is actually a gap in the ancient continuum of green roofing.  Deep traditions of sod roofs, much elaborated upon with local gems, are common in Ireland, Britain, Scandinavia, Japan, Northern China and Mongolia, the Middle East, and Native North America.  Though tipis and wigwams are the common image of First Nations housing, sod roof, semi-subterranean houses predominated through the north half of the continent.  Adobe predominated in the south half.

 Bringing the green roof into the modern era bears some explanation.  There are two basic types of green roofs: those added to existing roofs, and those designed into the building plan at the start.  

Waterproof barrier must be placed between green roof drainage and the existing roof.

An air gap between the two roofs is needed to retard 'sweating' and excessive, constant moisture.

The total weight of the green roof, wet and planted, must not exceed to load per square foot the existing roof can bear.  

The green roof must have sufficient drainage away from the underlying roof.

Plants you use must endure extremes of heat, sun, wind, and cold.  Alpine and coastal plants are great candidates.  Also, shallow-rooted plants work best.

 

Thanks to the New England Wildflower Society for their article



Watch below how we intend to insulate the walls of our Inis Meain  shed. using hemp mixed with lime creates a breathable surface that should retain heat and eliminate dampness. Read here for more details on the process and materials involved.

Its a very simple and effective process as this short video explains.





If we decide to put help and lime on the outside of the adjoining cottage, we might use the Hempire solution detailed here.


One day we hope to install a stove like this, the Saey Cuig
