Suzanne with black eyes
Black-eyed Susan (Thunbergia alata) is a perennial climber that thrives in warm climates and is often grown as an annual in our latitudes. Originally from East Africa, it is prized for its abundant flowering and voluble habit, which enables it to cling naturally to trellises and pergolas. Its flowers, in shades of yellow, orange or white, have a characteristic dark centre. It grows to a height of 10 metres.
It usually reaches a height of 1.5 to 3 metres and flowers from June until the first frost. Its heart-shaped foliage remains semi-evergreen in mild regions.
To thrive, Black-eyed Susan needs rich, well-drained, slightly moist soil. It prefers a sunny spot but will tolerate part shade. Regular watering is necessary during dry spells, while preventing excess water from escaping. Sow in a greenhouse.
Sow indoors from February to March or directly in the ground after the last frost. Germination takes around…
