Plant Description:
Appearance: Washingtonia robusta is a tall, slender palm tree with a single, straight, and cylindrical trunk that can reach impressive heights of up to 20 to 30 meters (65 to 100 feet). The trunk is usually grayish-brown and smooth, marked with prominent ring-like scars from the shed fronds. In mature specimens, the trunk can take on a slight swelling at the base, enhancing its striking visual appeal.
Leaves: The crown of Washingtonia robusta is composed of large, fan-shaped leaves, giving the palm its common name, “Mexican Fan Palm.” The leaves can grow up to 1.5 to 2.5 meters (5 to 8 feet) in diameter and are divided into numerous stiff segments that radiate from the leaf’s center. The leaf color is a bright green, and the petioles (leaf stalks) are armed with small, sharp spines.
Flowers and Fruits: Washingtonia robusta is a monocarpic palm, meaning it flowers only once in its lifetime, typically after several decades of growth. The flowers are small, cream-colored, and held on large, branched inflorescences that emerge from among the leaves. The flowering event is visually impressive, although it’s relatively short-lived. After flowering, the palm produces small, round, dark brown to black fruit that contains a single seed.
Growth Rate: One of the notable characteristics of Washingtonia robusta is its rapid growth rate. Under favorable conditions, it can put on several feet of height per year, making it a sought-after choice for landscaping projects that require a quick vertical impact.
Cold Hardiness: This palm tree is known for its tolerance to a range of environmental conditions. It is moderately cold-hardy and can withstand temperatures as low as -5°C to -7°C (23°F to 19°F) for short periods. However, it thrives in warm and sunny climates with mild winters.
