Guide to growing Black Eyed Susan Vine - Thunbergia
Thunbergia are half hardy climbing plants. They bloom from summer to autumn and usually carry flat or trumpet like flowers.
The Thunbergia flowers may be white, yellow or orange, and often have a black centre.
There are many different species of Thunbergia grown in the garden and some of the common varieties include Black eyed Susan Vine, Orange clock vine, Clock vine and Sky vine.
How to grow Black Eyed Susan Vine
It is best to start growing black eyed Susan vine indoors when growing from seeds. The process should be started about 7 or 8 weeks before mid spring. The seeds should be sown into peat pots and lightly covered. It should take about two or three weeks for black eyed Susan vine and other Thunbergia seeds to germinate at a temperature of 18 to 25 degrees centigrade.
Once ready transplant the vine outdoors in mid spring (when it always remains above 10 degrees centigrade) with a spacing of 30 to 50cm. Ideally black eyed Susan vines should grow in a sunny or a partially shaded area of the garden that has a moist, organic soil.
Caring for Black Eyed Susan Vine
These vines like to have moist soil so keep well watered during the growing season. If you require more black eyed Susan vine (Thunbergia) then you can take cuttings in the spring.
