Arum rupicola, commonly known as Rock Arum, is a perennial herb that is deciduous or semi-deciduous depending on the climate. It is native to rocky slopes and woodland margins in the Middle East and Transcaucasus region. This plant typically grows to a height of 1-1.5 feet (30-45 cm) and a width of 0.5-1 feet (15-30 cm). The Rock Arum has arrow-shaped leaves and produces inflorescences consisting of a hood-like spathe, which can be purple, and a central, rod-like spadix that may be red. The flowering season is in the spring, and while the flowers are not particularly showy, they are intriguing and have a unique appearance.

Rock Arum is valued for its foliage and the architectural form of its inflorescences. It is often used in shaded garden areas, woodland plantings, and as an underplanting for larger shrubs. It prefers part shade but can tolerate full shade, requires medium amounts of water, and thrives in well-drained soils rich in organic matter. While it is not commonly afflicted by diseases, it can be susceptible to root rot if overwatered or planted in poorly drained soils. It is not known for being invasive and does not have aggressive roots, making it a safe choice for most garden settings.CC BY-SA 4.0
