Description
Ophiopogon japonicus is a short, grass-like herb that typically grows up to 30 cm tall. Its dark green, linear leaves measure between 20 to 40 cm in length and about 0.5 cm in width. The plant produces small, bell-shaped flowers that range in color from pale lilac to white, appearing on a short raceme. The fruit of the O. japonicus is a distinctive cobalt blue berry, less than 1 cm wide.
Cultivation
Renowned for its ornamental use, Ophiopogon japonicus serves as an excellent groundcover due to its turf-like appearance and low maintenance requirements. Several cultivars have been developed, including:
‘Albus’: Known for its white flowers.
‘Compactus’ and ‘Kyoto Dwarf’: Dwarf varieties that do not exceed 4–5 cm in height.
‘Silver Mist’: Features variegated leaves with white stripes.
This plant thrives in full sun to partial shade and can endure temperatures as low as -20°C when dormant during winter in normal soil conditions. While it is sometimes sold for freshwater aquaria, it is not a true aquatic plant and will only survive for a few months underwater before dying. Propagation is typically done through side shoots.
Traditional Uses
In traditional Chinese medicine, Ophiopogon japonicus is revered for its medicinal properties. Known as mai men dong, both the plant and its tubers are used to address yin deficiency. According to the “Chinese Herbal Medicine Materia Medica,” the herb is sweet, slightly bitter, and slightly cold. It enters the heart, lung, and stomach channels, nourishing the yin of these organs, clearing heat, and soothing irritability. Liriope spicata is often used as a substitute for this herb.
Conclusion
Ophiopogon japonicus is a multifaceted plant that offers aesthetic value as an ornamental groundcover and significant therapeutic benefits in traditional medicine.
