Rosemary is a widely appreciated herb, found in gardens for its aromatic foliage and attractive appearance. Many gardeners cultivate it for both ornamental and culinary applications. A common question is whether its creeping variety can be used like its upright relatives. This article explores the edibility of creeping rosemary and important considerations for its use.
Edibility of Creeping Rosemary
Creeping rosemary (Rosmarinus officinalis ‘Prostratus’) is edible. Like all Rosmarinus officinalis varieties, its leaves and tender stems are safe to eat. It shares the same botanical classification as upright rosemary, possessing similar compounds for flavor and aroma. Its edibility stems from its genetic lineage within the Lamiaceae family, which includes many commonly consumed herbs.
Flavor and Culinary Uses
Creeping rosemary’s flavor is consistent with upright rosemary, offering a pungent, piney, and somewhat camphoraceous taste. Some suggest it’s slightly milder, possibly from harvesting younger, more tender growth. This makes it versatile in the kitchen, adding depth to various dishes.
It can be incorporated into marinades for meats like lamb, chicken, or pork, imparting its distinct aroma. It also enhances roasted vegetables, especially potatoes and root vegetables, when added fresh. The herb works well in baked goods like focaccia bread or rosemary shortbread. It can also infuse oils, vinegars, or beverages like lemonade for a unique twist. Both fresh sprigs and dried leaves are suitable.
Identifying Creeping Rosemary
Proper identification is important for safe use. This variety has a distinctive low-growing, trailing, and spreading habit, often cascading over walls or along the ground. Its stems are flexible and tend to root where they touch the soil, forming a dense mat. The leaves are needle-like, about an inch long, with a dark green, somewhat leathery upper surface and a silvery-white, fuzzy underside.
Small, typically pale blue flowers appear along the stems, usually in late winter or early spring, though blooming can occur intermittently in mild climates. These flowers are also edible and contribute a delicate, slightly sweet flavor. Its prostrate growth habit is the primary visual cue distinguishing it from taller, upright rosemary cultivars. Leaf and flower characteristics remain consistent across the species.
Safety Considerations and Precautions
Several safety precautions should be observed when consuming creeping rosemary. Ensure the plant has not been treated with synthetic pesticides, herbicides, or fungicides, as these chemicals can be harmful if ingested. Source rosemary from a trusted garden or cultivate it yourself using organic practices. Before use, thoroughly wash harvested sprigs under cool running water to remove dirt, insects, or surface residues.
Individuals with known allergies to Lamiaceae family plants (including mint, sage, and lavender) should exercise caution. While generally safe, consuming very large quantities can interact with certain medications (e.g., blood thinners or diuretics) or exacerbate pre-existing medical conditions. Consume herbs in moderation and consult a healthcare professional if you have health concerns or are on medication.
