''In flight school, Ace was a loose cannon. He had little respect for authority, shooting his mouth off at the smallest provocation. But, when it comes to garden warfare, he follows the rules of engagement, taking out distant targets with cold, steely-eyed precision. For zombies, the space around Ace is a danger zone!''

Trivia

 * It is a portmanteau of "ace" and "Aspearagus", seeing as it has a fighter pilot hat.
 * Its damage is similar to the Shamrock, but it shoots farther and does not hide.
 * Shamrock's spears are bigger than Aspearagus'.
 * If the player looks closely, it has a crosshair on its helmet.
 * Its spears resemble rockets. In fact, if the player looks close enough, there is a small fire in the Acespearagus' spears.
 * It is one of the few plants with a confirmed gender, being male.
 * In the Facebook description, the word "garden warfare" may be a nod to Plants vs. Zombies: Garden Warfare.
