This plant is originally from eastern Cape and KwaZulu-Natal but is now very happy in the shade in the plectranthus flower-bed near the main entrance to the Park. The leaves are ovate and lightly toothed. The flowers are among the largest of all the Plectranthus species. They grow in racemes at the tip of the stem but only on one side.
Plectranthus comes from the Greek plektron meaning a spur and anthos, flower; referring to the spur that is found at the base of the corolla tube of the type species for the genus while saccatus, meaning bag-like in Latin, refers to the shape of the corolla tube.
