The genus name, Grevillea, honors Charles Francis Greville, a British horticulturist and co-founder of the Royal Horticultural Society. The specific epithet, lavandulacea, refers to the resemblance of the flowers to those of Lavandula, the genus of true lavender plants. Description Grevillea lavandulacea, commonly known as Lavender Grevillea or Lavender Spider Flower, is a visually captivating flowering shrub that displays distinct physical characteristics. Here is a detailed description of its physical appearance: Size and Growth Habit: Grevillea lavandulacea is a low to medium-sized evergreen shrub that typically reaches a height of 1 to 3 meters (3 to 10 feet) and spreads to a similar width. The overall growth habit of the plant is bushy and rounded, with multiple branches arising from the base. Branches and Foliage: The branches of Grevillea lavandulacea are slender and covered with fine hairs, which give them a silvery-gray appearance. The foliage is composed of numerous narrow, linear leaves that are approximately 2 to 5 centimeters (0.8 to 2 inches) long. The leaves have revolute margins, meaning the edges curve downward, which adds to the plant's overall grace and charm. The color of the leaves is generally green, providing an attractive backdrop for the showy flowers. Flowers: The flowers of Grevillea lavandulacea are the plant's most striking feature. They are arranged in dense clusters, called inflorescences, at the terminal ends of the branches. Each inflorescence contains numerous individual flowers, creating a profusion of blooms when in full bloom. The tubular flowers have a delicate and intricate structure. The long, slender styles that protrude from the center of the flower are often described as resembling spider legs, hence the common name "Spider Flower." The flowers are typically a pale to deep lavender color, although variations with pink or white hues can also be found. The vibrant blooms, combined with the abundance of flowers in the inflorescences, create a visually stunning display. Overall Appearance: Grevillea lavandulacea presents an overall aesthetic appeal with its compact and bushy growth habit, silvery-gray branches, and graceful foliage. The lavender-colored flowers add a touch of elegance and vibrancy to the plant, making it a standout feature in gardens, landscapes, and natural habitats.
