Gertrude Jekyll, like Monet, was a painter with poor eyesight, and their gardens - his at Giverny in the Seine valley, hers in Surrey - had resemblance's that may have sprung from this condition. Both loved plants that foamed and frothed over walls and pergolas, spread in tides beneath trees; both saw flowers in islands of colored light - an image the normal eye captures only by squinting.

Or perhaps you notice a congregation of ladybugs on a rose stalk. Don't invoke the old nursery saying and ask them to fly away home. Their house is not on fire. Your roses are, with aphids, which the ladybugs are feeding on - and you can bless yourself that they have come to your rescue.

I love blue more than any other color. I am inordinately attracted to any blue substance: to minerals like turquoise and lapis lazuli, to sapphires and aquamarines; to cobalt skies and blue-black seas; Moslem tiles - and to a blue flower whether or not it has any other merit.

A garden is a private world or it is nothing.

Sooner or later every gardener must face the fact that certain things are going to die on him. It is a temptation to be anthropomorphic about plants, to suspect that they do it to annoy.

It takes a while to grasp that not all failures are self-imposed, the result of ignorance, carelessness or inexperience. It takes a while to grasp that a garden isn't a testing ground for character and to stop asking, what did I do wrong? Maybe nothing.
