Introduction to Cherry Laurel and Portuguese Laurel
Cherry laurel (Prunus laurocerasus) and Portuguese laurel (Prunus lusitanica) are both members of the Rosaceae family and are commonly used as ornamental plants in gardens, parks, and along streets. They are particularly valued for their evergreen leaves, which provide year-round interest and can be used to create hedges, screens, or specimen plants. Despite sharing some similarities, such as their broad, glossy leaves, these species exhibit a range of differences that are crucial for gardeners and landscapers to understand.
Origin and History
Cherry laurel is native to the regions of southeastern Europe and southwestern Asia. It has been cultivated for centuries, primarily for its elegant appearance and ability to form dense hedges. On the other hand, Portuguese laurel originates from the Iberian Peninsula, specifically from the mountainous areas of Portugal and Spain. Its cultivation history is less documented than that of cherry laurel, but it has gained popularity in recent years for its compact growth and tolerance to drought.
Physical Characteristics
One of the most notable differences between cherry laurel and Portuguese laurel is their physical appearance. Cherry laurel has larger leaves, typically measuring between 10 to 15 cm in length, with a deep green, glossy appearance. These leaves are oblong in shape and have a slight undulation, adding texture to the plant’s foliage. In contrast, Portuguese laurel has smaller leaves, usually around 5 to 10 cm long, which are also glossy but more elliptical in shape. The smaller leaf size contributes to a more compact, dense foliage when used as a hedge.
Leaf Color and Variability
The color of the leaves can also vary slightly between the two species. While both display deep green leaves, cherry laurel may exhibit a slight blue-green tint, especially in the younger leaves. Portuguese laurel, however, maintains a consistent green color throughout its foliage. Additionally, the new growth on cherry laurel can have a bronzy tint, which fades to green as the leaves mature.
Growth Habits and Conditions
Understanding the growth habits and conditions preferred by each species is crucial for their successful cultivation. Growth Rate is a significant factor; cherry laurel tends to grow faster than Portuguese laurel, especially when young. Cherry laurel can grow up to 6 meters tall if left unpruned, forming a large, dense shrub or small tree. In contrast, Portuguese laurel typically reaches heights of up to 4 meters, making it a more compact option for smaller gardens or where a lower hedge is desired.
Soil and Climate Tolerances
Both cherry laurel and Portuguese laurel are considered adaptable and can thrive in a range of conditions. However, soil tolerance differs slightly between the two.
