Asparagus is a long-lived perennial that takes 2-3 years to establish but then produces harvests for 15-20 years or more. It requires patience upfront but rewards with decades of spring spears. Male crowns are more productive than female plants as they don't waste energy on berry production. One of the most rewarding investments in any Australian home garden.
