A standard perennial alfalfa whose good yields continue for 4-5 years and then can be plowed under and re-seeded. Alfalfa is an excellent choice for the home gardener to enrich soil that won't be used for 2 or more years, and can make a nutritious mulch or compost by cutting it several times in the course of a summer. Does a good job of crowding out weeds. If alfalfa hasn't been grown on your soil in the past, an inoculant is recommended and this seed is not treated with inoculant. Grows about 3 feet tall. Sow 1/2 lb for 1000 sq. ft.
