Asparagus Seeds - Purple

Purple asparagus seeds produce a long-lived perennial plant with upright, spear-producing growth that develops into a fern-like mature form. This asparagus type is suited to temperate climates and is commonly planted in dedicated garden beds where plants can establish for multiple growing seasons. It adapts well to a range of soil types when drainage is good and requires patience during establishment, as harvest typically begins after plants are well developed. Purple asparagus is suitable for home gardens and small-scale plantings intended for long-term cultivation.
