If growing it 'for fun' then go ahead - but if you want to establish a productive asparagus bed then my best advice is to buy crowns of an all male variety.
Seeds will produce male and female plants. Male plants are more long-lived and produce an earlier crop of much more productive plants. Female plants produce seeds the production of which will compete with the crowns for nutrients/energy.
If your neighbour wants his/her asparagus bed to remain productive I would advise pulling out all fruit-producing fern and any seedlings.
Hope that's helpful
