He who hunts for flowers will finds flowers; and he who loves weeds will find weeds. – Henry Ward Beecher

We can in fact only define a weed, mutatis mutandis, in terms of the well-known definition of dirt – as matter out of place. What we call a weed is in fact merely a plant growing where we do not want it. – E.J. Salisbury, The Living Garden, 1935

A weed is but an unloved flower. – Ella Wheeler Wilcox

But make no mistake: the weeds will win; nature bats last. – Robert M. Pyle
