"Marriage? It's like asparagus eaten with vanaigrette or hollandaise, a matter of taste but no importance," opined Françoise Sagan (1935-2004), French playwright and screenwriter of Bonjour Tristesse.
Nevertheless, the French have had a thing for asparagus ever since it infiltrated their border with Spain following the Arab conquest of the Iberian Peninsular.
Asparagus reached England by the sixteenth century. During the following hundred years it was being raised commercially. It was not until the late 1800s, nonetheless, that it was popularized as a favourite of Queen Victoria's son, Edward, Prince of Wales--along with strawberries. Later to become Edward VII, he established entente cordial, much appreciating both French fare and fairer sex.
Asparagus was a labour-intensive, laborious crop and so largely limited to the tables of the rich. Thanks to air transportation and modern production techniques this is no longer so. Still, it is not exactly cheap and imported quality questionable. Thus, some keen gardeners desiring to become gourmet descendants of royalty, choose to establish their own plantings. Since asparagus beds have been known to remain productive for a century or more, some work is initially necessary--perhaps more than most envisage.
Choose a bright, sunny location in well-drained soil free from competing tree or shrub roots. For a double row prepare a trench, three feet (a metre) wide, a foot (30cm) deep. Spread composted animal manure on the bottom and fork over. Backfill with soil/composted manure or triple mix to ground level, tamp down to 4 to 6 inches from surface and apply a generous amount of bone meal fertilizer. Space asparagus crowns 6 inches (15cm) from sides of trench, a foot (30cm) apart; cover with 3 inches (7cm) of soil/compost or triple mix; as shoots ('spears') emerge fill in the more soil mix. For the first season, weekly weeding is advisable.
One of the reasons for commercial asparagus' high price is that, left to itself, the plant is dioecious, that is, having separate male and female plants. Since the female plants are less productive, older selections such as the venerable 'Martha Washington' are half female, half male. Newer cultivars are almost all higher-yielding male, such as Jersey Giant, Jersey Knight, and Jersey Prince. Suggests Richters of A. officinalis 'Jersey Giant':
Plant this year and harvest your first crop next spring! Male variety are 35% more productive than other "co-ed" varieties. About 95% of plants are male.
Not surprisingly, the sexual orientation of asparagus has attracted researchers. Working with an international team of breeders and genome scientists, plant biologists at the University of Georgia have sequence the genome of garden asparagus as a model for sex chromosome evolution. Their study appeared in the journal Nature Communications.
More down-to-earth advice emanated with the American radio broadcaster Paul Harvey (1918-2009) who drew a comparison when he recommended: "Government has to be cut back like asparagus . . . every day . . . or it gets away and goes to seed."
