Heen Bovitiya (Osbeckia octandra)

Product description

This small herbaceous plant is native to Sri Lanka and is known for its many medicinal properties. The leaves, stems and bark are traditionally used in powder form in Sri Lanka to treat various ailments and diseases, including e.g. diabetes, liver damage and cancer. Besides its medicinal uses, the plant also seems to be very suitable for combating soil erosion. Its extensive root system, ability to grow in poor, acidic soils and high growth rate make the plant interesting for planting on degraded land. But the ornamental value of the plant should not be underestimated either. The leaves are graceful with a striking vein and fine red hairs. The flowers are bright pink with large yellow stamens. 

Outside the tropics, this species is best kept indoors as a houseplant. If sown in spring and during a warm summer, however, it can also flower outdoors as an annual. The minimum temperature is around 10grC and the plant likes a semi-sunny position. The best soil is a sandy mixture that is allowed to dry out between watering.  

Sowing description: Sow the seeds in sowing soil at a temperature of around 20-25 degrees Celsius. There is evidence that adding some wood ash, to mimic a recent forest fire, may be beneficial for germination. Keep the soil constantly slightly moist. Germination usually follows after a few weeks.
