Growing Sorrel in Zone 3B

Sorrel is an underused perennial herb with a sharp, lemony flavor. It’s one of the first edible greens to emerge each spring.

Zone 3B has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.

Top Growing Tips

• Perennial in most zones; dies back in winter, returns reliably
• Young leaves are mildest; larger leaves get more intensely sour
• Remove flower stalks promptly to prevent bolting and keep leaves coming
• Add to soups, egg dishes, and sauces for bright lemony flavor
• High in oxalic acid — eat in moderation, especially if prone to kidney stones

Companion Planting
