Black-Eyed Susan Overview
Black-Eyed Susan is a vigorous tropical vine with orange or yellow flowers and a dark purple center. In Hawaii, it can be seen on many hillsides, where its bright blooms stand out against green foliage.
This plant is native to Africa and is known scientifically as Thunbergia alata. It grows quickly in warm climates and uses nearby plants, fences, trellises or other supports to climb and spread. Because of that fast growth, it can cover a sunny area in a short amount of time when conditions are right.
Flowers, Growth and Garden Use
The flower is easy to recognize because of its dark center, which gives Black-Eyed Susan its common name. The petals are usually orange or yellow, creating a strong contrast with the purple-black center. This simple color pattern makes the plant noticeable even from a distance.
In Hawaii landscapes, Black-Eyed Susan can add color to fences, garden edges, slopes and trellises. It works best where it has sunlight and room to climb. Because it grows fast, it may need trimming or guidance to keep it from spreading beyond the area where it is wanted.
