Pentanema montanum, commonly known as Mountain Goldenrod, is a perennial herb native to the Mediterranean region, including mountainous areas and rocky slopes. It exhibits a moderate growth rate, typically reaching 1-3 feet (0.3-0.9 meters) in height and 1-2 feet (0.3-0.6 meters) in width. This plant is characterized by its lanceolate leaves and clusters of bright yellow, daisy-like flowers that bloom in the summer, adding a splash of color to the garden. The flowers are attractive to pollinators such as bees and butterflies.

Mountain Goldenrod is valued for its drought tolerance and ability to thrive in poor soils, making it a suitable choice for xeriscaping and rock gardens. It is also used in borders and wildflower meadows for its low maintenance and long blooming period. Gardeners appreciate its adaptability to full sun conditions and its preference for well-drained sandy or loamy soils. While generally pest-free, it can occasionally suffer from mildew or root rot in overly moist conditions.CC BY-SA 4.0
