As a result, only the female feet of asparagus bear fruit. The genus Asparagus has 12 spontaneous species. There are 5 in the hexagon including Asparagus officinalis, A. albus, A. acutifolius, A. maritimus and A. tenuifolius. All are edible. However, the maritime asparagus (A. maritimus) has a very pronounced bitterness. Asparagus emits rhizomes, which evolve to give new stems

Agribusiness of Agriculture: Cultivation of asparagus
Asparagus flourishes well in areas where the ground freezes in winter and in regions with dry winters.
Agribusiness of Agriculture: Soil preparation and sowing
Asparagus prefers light, well-drained soils that warm quickly in the spring. Soils engorged with water are prejudicial to it. The seedbed should be about 1.20 m wide. It will have to be rid of any perennial grass and any root. Aging manure or compost will be incorporated during this step.
They do not have to waste energy to produce flowers and seeds. Some varieties selected like the American variety “Jersey Knight”, only produce male plants. Planting 1-year-old claws allows harvesting 1 year before planting seeded seeds. Seeding of seeds should be avoided as much as the shock of transplanting slows down production.
