Purple Passion, Heirloom Asparagus Seeds

Purple Passion — The Heirloom Asparagus With Deep Purple Spears, 20% More Sugar, and Unmatched Tenderness

Purple Passion is a stunning heirloom asparagus variety that produces large, deep purple spears with a naturally sweet, nutty flavor, setting it apart from standard green varieties. With up to 20% more sugar than green asparagus and less lignin in the stalks, Purple Passion delivers a noticeably sweeter flavor and more tender texture — delicious eaten raw or cooked. A long-lived perennial that, once established, will produce for 15–20+ years. Expect your first harvest 2–3 years after planting as the crowns establish.

Tip: Avoid cooking in aluminum pans. Place freshly harvested spears immediately in water to preserve moisture and crispness.

Why Grow Purple Passion?

Growing Notes

Start 12–14 weeks before the last frost or direct sow indoors or outdoors in early spring. Sow seeds ½ inch deep in fertile, well-draining soil. Transplant seedlings outdoors after frost danger has passed. Space plants 12–18 inches apart in rows 4–5 feet apart in full sun. Asparagus requires patience — do not harvest the first 2 years to allow crowns to establish. Begin light harvesting in year 2–3, and full harvests from year 3 onward. Top-dress with compost each fall. Plants will produce for 15–20+ years once established.
