MONADENIUM KEY FEATURES

Monadenium is a genus of about fifty species of perennial succulent, bushy, arboreal. This type of plant grows mainly in eastern or tropical Africa, in countries such as Angola, Namibia, Zimbabwe and South Africa. The genus is characterized by strong differentiations, depending on the area of ​​origin and distribution: some remind  small palms, others  have the stem covered with small tubercles on which the inflorescences sprout directly.

This variability suggests that these species are characterized by a strong adaptation to the environment. Some species produce annual vegetation from an underground tuber. Others keep fleshy fruit throughout the year. In the summer they produce small, petals-free flowers cup – shaped inside   yellow, red or brown wrappings.

The Monadenium, although it comes from drought-resistant territories, seems to prefer shaded areas than sun exposure. It is recommended to pay attention to the milk lymph contained in the tissues: it may be irritating due to the presence of resins and euphoric acid.
