greening up our Fine City

Went trolling about in Norwich at the weekend and was delighted to discover a "living wall" on the newly extended Marks & Spencers store on Rampant Horse Street.
According to the EDP, it covers 152sq m. Plants quite happy to grow vertically up this British institution include:  

Armeria maritima
Blechnum spicant
Galanthus nivalis
Galium odoratu
Geranium macrorrhizum
Hebe pinguifolia ‘Pagei’
Helleborus argutifoliu
Luzula nivea
Phyllitis scolopendrium
Sarcococca humilis
Thymus vulgaris

Yes please, Norwich. More of this and less ghastly winter bedding.
