Cereal Rye (Winter Rye)
Secale cereale
Family Poaceae

Cereal rye forgives every procrastinator. Sow it absurdly late in fall — in cold soil where nothing else will sprout — and it still comes up, standing guard over bare beds all winter while its deep roots punch through hardpan and mop up leftover nitrogen that rain would otherwise wash away.
Come spring, the flattened stalks become a ready-made mulch you plant straight into, with weeds suppressed beneath. This is true rye — the grain of rye bread, not lawn ryegrass — and the most forgiving soil tool a garden can own. Keep a bag by the door for every bed you empty.

Terminate by mowing/crimping at flowering in spring, then plant into the mulch.
