Phuopsis stylosa, the Caucasian crosswort or large-styled crosswort, is a low-growing, mat-forming, aromatic perennial plant in the madder, or bedstraw family Rubiaceae. It has whorls of narrow, aromatic leaves and terminal clusters of tubular pink flowers. Phuopsis stylosa is native to the Caucasus and Iran, and is widely grown elsewhere as a garden plant.
The plant gives off an odor which can be confused with that of some Cannabis species.
This ground cover plant has a magnificent and very particular summer flowering (from June to August). Indeed, the plant forms many small flowers (between 30 and 50) of pink color which form a round bouquet at the end of the stems. But this plant is best known for its fragrant characteristics since Crucianella stylosa exudes a scent of Marijuana.
Crucianella stylosa is a fast growing plant, hardy to at least -20° C, drought resistant and requiring no special maintenance. For its cultivation, this cannabis-scented plant requires a light, fresh and well-drained substrate. Sow in September-October under frame or cold greenhouse or in spring between March and May. The germination rate is around 90%.
