Your house is a cliff

Think like a plant.  Go on, give it a try.  I've found that peering at the urban environment from a plant's perspective seems to make them a lot happier.  For example, a Rosemary plant in your kitchen garden outside the back door would see itself as sitting at the base of a cliff, which is fine if said outcrop faced South and caught the heat of the day along with the sun's rays.  This is what Rosemarinus officinalis love - a bit of mediterranean heat.  If, however, your yard points North,  you should be thinking of damp, dense walks through light-dappled forests or natural ferneries mottled with mosses and algae.  Your Rosemary would be completely out of place, and would naturally struggle.  Same goes for houseplants - they think they're living in a cave.  A warm, dry-aired and serendipitously-irrigated cave.  Our lighting doesn't do much for plants, so they seek the natural light through the apertures (windows) of the cave walls.  

I apply these ideas to the landscaping in my garden designs too - I wouldn't put a whitewashed rendered wall in a shady garden in Glasgow - it just goes green with algae in no time.  Best to go for a textured stone or timber that'll grow a patina of mosses, liverworts and ferns all by itself. 

With sunlight often at a premium in this country, especially at this time of year, thinking like your plants will reward you with surprising toughness and unfurling beauty through the growing season to come.
