Planting Seeds: Why I love working with plants
28 March 2014 Architectural Association, London   A scribbled stem and tangled suggestion of branches - the miscellaneous vegetation of architectural sketch lore – humble plants are drafted in to provide that crucial nod to a softer, slower side of life.  Plant life gets a raw deal, though.  Reduced to the generic, some 315,000-odd species are overlooked as a creative resource - but to me plants are the ultimate palette, the most intriguing, restless, stimulating material.   Every plant comes as a specified unit: that is, it is not simply a rose, an oak or a daisy.  Botanists have done all designers an enormous favour by using a classification system which crosses language barriers and allows us to pin-point the exact criteria we desire.  Genus, species and cultivar - these are your allies.  Thinking of a birch tree – with horizontal patterns in the bark:  Betula.  A delicate arrangement of trailing branches: Betula pendula.  A sturdier, more upright form?  Betula utilis.  Seeking the whitest-of-white bark on this birch tree?  Betula utilis Jacquemontii.  A slow growing version for a smaller space?  Betula utilis Jacquemontii ‘Snow Queen’.  And so it goes, enabling your ‘common’ oak to be agreed on by those for whom an English woodland is as alien a space as the terrain of Mars (Quercus robur - the English Oak tree was associated with Mars Silvanus, the god of agriculture and healing, by the ancient Gauls and the Romans).

The quirks of evolution plus extensive human meddling mean that some cultivars will flower in winter, whilst others of the same species peak in summer.  Autumn riches can be played off against the strong, solid dependability of an evergreen, framed and contained, or massed, to run riot and clash in a short-lived extravagant flourish.  A plant will flare up, distract you, lead you astray, and then cool off, allowing your gaze to trail elsewhere...   Plants offer up the opportunity to create a space with no fixed end.  A tree may grow for centuries, becoming broader, gnarly, riddled with holes, before dying slowly and then entering the incredible process of decay – weathering, fading, rotting, warping, splitting, springing out violent orange crops of fungi and thickets of vivid moss.  A snowdrop (Galanthus) bursts out of the ground in late winter, provides an urgent flurry of white and vanishes, unseen for another year.  Yew trees (Taxus baccata)  hold the secret of eternal youth: by cutting them back in their ‘juvenile’ stage, they remain buoyant and flexible, able to be sculpted over and over again.

If the plant got there first, it is offering its own set of parameters to a space: it sets an agenda.  The specific nature of that plant can imbue a place with folklore, with atmosphere, with shadows, with scent.  It can determine the light, welcome or repel visitors, dictate the view.
