How to Grow Purple Asparagus

Purple asparagus is a variety of asparagus that is tender and usually it is possible to eat the whole asparagus from its tip to its base.[1] Purple asparagus is sweeter than green or white asparagus and produces thicker spears.[1] Learn how to grow purple asparagus from crowns.


  1. 1
    Purchase or obtain a good healthy asparagus crown of the purple variety.
  2. 2
    Plant the crown anywhere from 6 inches to a foot (15cm to 30cm) deep in fertile rich soil.
  3. 3
    Water the soil where you planted the crown. Maintain a constant moisture for the majority of the asparagus's active growth.
  4. 4
    Allow the asparagus to grow for 1 to 2 years of undeterred growth.
  5. 5
    Harvest. Once the waiting period is over, you may begin harvesting your asparagus by cutting the stalks to the ground for three month. After the third year has elapsed, you may extend the cutting season to two months.
    • Do not cut out all the stalks or you will kill the plant. Always leave a few to nourish the plant and allow for regeneration.
  6. 6
    Enjoy your purple asparagus in any asparagus recipe.


  • Cut the stalks before they get too big to achieve the best flavor.
  • Plant asparagus crowns in early spring for best results.


  • Do not eat the berries of the asparagus plant; they are toxic.
