history
Often paired in proverb form with 有心栽花花不发 (yǒuxīn zāi huā huā bù fā, 'flowers planted with care fail to bloom'), the longer saying contrasts deliberate effort that flops with idle action that thrives.
usage
Also commonly written 无心插柳柳成荫 (yīn → yīn, with 荫 instead of 阴) — both refer to the willow's shade. The 荫 version is more common in modern texts.
