Garden quote

[baggins]

Does anyone know where this quote came from. I have found it on some sites but never with an author  to it.

To plant a garden is to believe in tomorrow.

[Clanad]

Not sure of your quote, but another, similar is,

Faith is planting a tree under whose shade you know you'll never sit...

Apparently Jewish in origin...

[jake-the-peg]

Of all the wonders of nature, a tree in summer is perhaps the most remarkable; with the possible exception of a moose singing "Embraceable You" in spats.
-- Woody Allen

[Octavius]

"Gardening is a way of showing that you believe in tomorrow."

I think the author is unknown, or at least uncredited.

I'm fairly sure that it will be a compaction of, or a paraphrase of, the sentiment/s at the end of Voltaire's 1759 novel Candide.

The young Candide lives in the little German principality of Thunder Ten Tronck, under the guidance of his tutor, Pangloss, a theorist of optimism. A liaison with his beloved Cun�gonde causes him to be exiled, and soon afterward the principality is sacked by the Bulgars, who rape Cun�gonde and leave Pangloss for dead. Candide then encounters every kind of eighteenth-century horror, from enslavement by the Turks to bondage on a French galley, and ends up on a little farm near Constantinople, wisely counselling Pangloss that the only worthwhile thing for people to do is to cultivate their gardens.

But then again; maybe not. P.S. the book sounds a dirge but it's actually bloody funny.
