Strophanthus wallichii is a perennial vine or creeper, native to Indian subcontinent. It is an ethnomedical plant, commonly used in traditional medicine in India. The plant has long, dark green leaves and its bark is light red-brown in color. The bright red and crimson, vinous flowers sprout from the twig ends of the vines in February-March.
This plant is best suited to growing in a pot and prefers a sunny or semi-shaded position. It grows very well in USDA Zone 9-11. It is a fairly drought-tolerant plant but regular watering is recommended during the summer months.
If you are growing Strophanthus wallichii in a pot in a region where the temperature falls to low levels, then it is important to take extra care when caring for the plant. Make sure the pot has adequate drainage, as this will help in keeping the root system of the plant protected in cold weather. When the temperature falls below 40Fs, it is important to provide some protection to the plant by moving it to a location with better protection from cold winds.
Regular pruning of the plant is recommended not just to ensure optimal growth, but also to help keep the size of the vine from becoming too large. Strophanthus wallichii responds well to fertilizer, so it is recommended to give the plant a dose of fertilizer every 3 months or so.
Overall, Strophanthus wallichii is a beautiful and rewarding plant to have in your garden. With the right care, it will bring its vibrant red, crimson and vinous flowers to life and help create a stunning display in your garden.
