Forgotten plant #theyellowbell

The yellow bell is an almost forgotten plant in Nigeria (although it is not native to our country), and this is sad owing to the fact that it is the face of the 20 kobo stamp. The flowers are bright yellow and grow in clusters leaves are bright green and sharply toothed, and are either hairy or smooth. If not tamed, it can grow like a wild weed. However, its bright yellow adds a brilliant variety to gardens. Please bring back this plant I really do miss seeing it around.
