The vegetable life does not content itself with casting from the flower or the tree a single seed

The vegetable life does not content itself with casting from the flower or the tree a single seed,

but it fills the air and earth with a prodigality of seeds,

that,

if thousands perish,

thousands may plant themselves,

that hundreds may come up,

that tens may live to maturity;

that,

at least one may replace the parent.
