Hibiscus cannabinus is an unusual member of the hibiscus family grown for cash crop paper making. They germinate in 24 hours in heat and can reach 18ft tall in 9 months of growth, but more likely 6ft to 8ft in a UK Summer. Useful for a fast growing foliage plant in a tropical border with pale lemon yellow flowers. We have a new strain now with palmate leaves and larger 4” flowers.
