When you picture a laurel, the mind often drifts to ancient Greece, to victorious athletes crowned with leafy wreaths, or to the distinguished halls of academia where scholarly achievement is marked by a circular emblem. While this cultural weight is universally recognized, the botanical reality behind the name is far more diverse. The term "laurel" applies to a wide range of evergreen shrubs and trees, many of which are unrelated but share similar glossy foliage and aromatic qualities. Understanding the different types of laurel reveals a world of distinct textures, growth habits, and landscape applications that extend well beyond the symbolic.
True Laurels: The Olives
Botanically speaking, the genuine laurel belongs to the genus *Laurus* and is a member of the Oleaceae, or olive, family. This classification immediately separates the true laurel from the dozens of unrelated plants that share the name. The most common species is *Laurus nobilis*, widely known as Bay Laurel or Sweet Bay. Native to the Mediterranean, this tree is the source of the bay leaves used to flavor stews and soups. When cultivated in the landscape, *Laurus nobilis* grows into a substantial shrub or small tree, characterized by its dark green, leathery leaves and small, inconspicuous yellow flowers. The growth habit is dense and somewhat upright, making it a natural choice for formal hedges or topiary. Unlike many ornamental shrubs, it tolerates pruning exceptionally well, allowing gardeners to maintain a specific size or shape without sacrificing its structural integrity.
Bay Laurel (Laurus nobilis)
Often simply called "laurel," *Laurus nobilis* is the standard against which other plants are compared. It is a staple in Mediterranean cuisine, where the leaves are dried and used to infuse soups, sauces, and braising liquids with a distinctively warm, slightly bitter flavor. Horticulturally, it serves a dual purpose. In the kitchen, the leaves are robust enough to withstand long cooking times, adding depth without dissolving. In the garden, the plant is remarkably versatile. It responds well to container culture, allowing for easy relocation to protect it from harsh winter winds in cooler climates. While it prefers full sun, it can adapt to partial shade, though variegated forms require more light to maintain their colorful foliage. The primary care requirement is well-drained soil; root rot is a significant risk in poorly drained locations.
The Lauraceae Family: Cassias and Their Kin
Expanding the search beyond *Laurus*, we enter the family Lauraceae, which includes some of the most popular landscape plants mistakenly called laurels. This family is primarily tropical, which explains the lush, tropical appearance of many of these shrubs. One of the most common sights is the California Bay Laurel, or *Umbellularia californica*. Though it shares the name and the aromatic leaf, it is distinct from the true bay. California Bay grows into a large, robust shrub or tree and is native to the western coast of North America. Its leaves are significantly larger and much more pungent than Mediterranean bay, often causing headaches if consumed in large quantities. Furthermore, the tree hosts the caterpillars of the California Tortoiseshell butterfly, adding an ecological dimension to its presence in the garden.
Camphor Laurel (Cinnamomum camphora)
Stepping further into the world of ornamental Lauraceae, the Camphor Laurel stands out due to its intense fragrance and controversial nature. Planted for its glossy, dark green leaves and reddish-brown bark that peels to reveal a mottled surface, this tree is a powerhouse of visual interest. However, its status as an invasive species in many parts of the world, including parts of the United States, has led to restrictions on its sale and planting. The name comes from the camphor oil stored within the leaves and bark, which releases a sharp, medicinal scent when crushed. While this scent is desirable in potpourri, it can be overwhelming in a enclosed courtyard. Gardeners in suitable climates must weigh the aesthetic appeal against the ecological impact and vigorous root system that can disrupt sidewalks and foundations.
Cherry Laurel (Prunus laurocerasus)
Perhaps the most ubiquitous shrub in the modern landscape is the Cherry Laurel, a member of the rose family rather than the laurel family. Despite the botanical mismatch, its shiny, dark green leaves make it the go-to choice for instant privacy. Unlike the airiness of a true laurel, *Prunus laurocerasus* grows into a dense, almost plastic-like hedge that blocks out sound and sight. It is the botanical equivalent of a solid wood fence, providing immediate impact. The name derives from the small, cherry-like fruit that follows the white flowers in spring, though these are generally inedible. The primary appeal of Cherry Laurel is speed; it grows quickly to the desired height and width. However, this rapid growth requires regular maintenance, and the dense mat of roots competes fiercely with nearby plants for water and nutrients.
The Misnamed "Carolina" and "Portugal" Laurels
Adding to the confusion are the plants in the Genus *Calycanthus*, commonly known as Sweet Bubby Bush or simply Carolina Allspice. These shrubs are native to North America and have aromatic, reddish-brown flowers that smell of fruit and spice, but they bear no relation to the Mediterranean laurel. They are distinct plants with a specific niche in the native garden. Similarly, the name "Portugal Laurel" is often used as a marketing term. In reality, this usually refers to a specific variety of Cherry Laurel (*Prunus laurocerasus* 'Rotundifolia') or sometimes a true laurel (*Laurus*) selected for its rounded leaf shape. Understanding that "Portugal" is a trade descriptor rather than a botanical classification helps gardeners make informed decisions based on the actual plant requirements rather than the suggestive name.
Choosing the Right Laurel for Your Space
Selecting the appropriate type of laurel requires looking past the common name and examining the growth habit and environmental needs. If the goal is a culinary herb that doubles as an ornamental standard, *Laurus nobilis* is the undisputed champion. For a fast-growing, evergreen screen where flowering is a priority, the Cherry Laurel delivers, albeit with high water and pruning demands. Those seeking a dramatic, tropical statement might opt for the Camphor Laurel, provided the climate is warm enough and the invasiveness is managed. Finally, the true botanical laurel, *Laurus nobilis*, offers the most versatility for container growing and culinary use. By matching the plant to the purpose—whether it be flavor, privacy, or pure aesthetics—the gardener can harness the true potential of these diverse evergreens.
