A pity about the rather uninformative - though catchy - title. In fact, this is a garden-design or planting-scheme book. And a super one too! A better designation might have been something like "Painting with Plants".
Think all those atmospheric NGS or National Trust gardens, scaled down to fit a typical plot, and with a less-than-one-gardener's work-load. Well, here are some ideas to achieve it.
As mentioned by another reviewer, the author imparts a few strong opinions that not everyone will agree with. But this doesn't detract from the book; if any readers are encouraged to analyse their own views more critically, it should only be beneficial for their own garden designs.
The text is effectively an informal discourse, and very readable. It's good to dip into too! It addresses an impressive range of garden situations, conditions, requirements and styles. It does not deal with garden constructions, only plants - a good thing, in my opinion.
I'm no lover of the sort of modernistic, modified-building-site, edifices that pass as gardens at places like Chelsea! Maybe neither is Stephen Lacey. Certainly, Real Gardening only exudes his unaffected enthusiasm for growing attractive flora...
There is nothing culinary. Nor does it explicitly cover practicalities like care and propagation. But little nuggets of useful information for many of the suggested plants are provided.
In summary, for a comprehensive, non-prescriptive, guide to artistically planning (or enhancing) your garden, I can't think of a better starting place than Real Gardening.
