Purple Passion Asparagus

Asparagus officinalis

Zones 7–13

Growing

Because this is a perennial, you will begin your garden by planting crowns in the winter. This variety thrives in fertile, well-draining soil with a pH between 6.0 and 7.5. While it can handle some salinity, you should avoid using salt to suppress weeds, as this can damage your soil's long-term health. If you are growing in a container, ensure the medium remains moist but never waterlogged.

When the shoots emerge in the spring, you can harvest them once they reach your desired thickness. Unlike green varieties, purple asparagus is prized for its high sugar content and lower fiber, making it exceptionally tender. Be aware that the beautiful purple pigment is sensitive to heat and may fade to green during the cooking process. To preserve the harvest, you can blanch the spears before freezing them for later use.

For the best flavor, harvest the spears when they are young and tender. If you find yourself with an abundance, you can also preserve them through canning. When storing your unwashed harvest in the fridge, keep them in a cool environment to maintain their sweetness. Always remember that the leaves and seeds of the plant are toxic, so handle them with care.
