Edmund Spenser

Amoretti 26. Sweet is the rose, but growes upon a brere

Sweet is the rose, but growes upon a brere;
Sweet is the iunipeer; but sharpe his bough;
Sweet is the eglantine, but pricketh nere;
Sweet is the firbloome, but his braunches rough*;
Sweet is the cypresse, but his rynd is rough;
Sweet is the nut, but bitter is his pill**;
Sweet is the broome-flowre, but yet sowre enough;
And sweet is moly, but his root is ill.
So every sweet with soure is tempred still,
That maketh it be coveted the more:
For easie things, that may be got at will,
Most sorts of men doe set but little store.
  Why then should I accompt of little paine,
  That endlesse pleasure shall unto me gaine!
