Our protagonist is a deciduous tree whose scientific name is Acacia horrida. It is popularly known as African carambuco, African buffalo acacia, orange mimosa, African aroma, sweet thorn and prickly acacia. It is native to South Africa, found in the savannas and deserts. It reaches a height of 3 to 6 meters, with a more or less rounded crown composed of branches armed with long thorns.

The flowers are grouped in small inflorescences in the shape of a ballerina’s pom-pom 1-2cm in diameter. The fruit is long, dry and inside we find round and hard blackish seeds. It has a life expectancy of about 30 years.
