Rosmarinus officinalis ‘Silver Shield’ is a robust, upright rosemary with sturdy, pale stems covered in fine, soft hairs and matte olive-green aromatic foliage. Naturally high in carnosic acid, it pairs a rich, lingering aroma with natural antioxidant protection for slow-cooked meats, while helping to shield fats from oxidation. Its antioxidant profile peaks in response to seasonal weather and growing conditions. Part of the X-Hishtil series, it shows impressive tolerance to powdery mildew.
