Description

The species is a shrub that grows up to 30 centimeters in height. It stands erect and is a bushy, rounded shape with erect or tortuous branches. The stems are 4-lined and are green when young, but later become red-brown and flattened, and still later turn grey. The species has 9-16 flowers that usually grow from two nodes. The flowers are 2-2.5 centimeters in diameter with elliptic and rounded buds, and their petals are bright yellow. It has 30-40 stamens, 3 ovaries, and 3-4 times as many styles as ovaries.[2]

Uses

H. rupestre, alongside several other species, is used as a traditional folk medicine in its native country, Turkey. Because of this, it has been investigated for its antibacterial properties, and ethanols extracted from it have been shown to be effective antimicrobials against Staphylococcus aureus and Bordatella bronchiseptica.[3]
