Family: Euphorbiaceae

Scientific name: Euphorbia obesa  Hook. f.

Common Names include: Sea Urchin, Baseball, Vetmensie

Conservation status: Listed in CITES appendix 2.

Origin: Garden origin (Nursery produced cultivar)
 

Dichotomous, trichotomous, quadritochomous...   ...polytomichous.

Polytomy is a form of cristation, an apex divided in 2, 3, 4 or in a lot of  smaller apexes.
It is very unusual to see such an Euphorbia obesa.
Some of these plants are very nice sculptures  one different to each other. There are also plants that show the classical line cristation and polytomy at the same time.

Description:  It is a single-stemmed plant with multiple apexes, creating very odd looking clusters.
It can grow to 20 cm in height with a diameter of 20 cm.

Cultivation: It likes a sunny position, but it can also be grown outdoors where the frost is not too severe. It can tolerate temperatures down to -5C (-10 if the roots are kept dry). It does best in a mineral soil, but is tolerant of a wide range of soil types. Good drainage is essential. Water sparingly during the summer months and keep dry in winter. It is a slow-growing, long-lived plant, and once established, it will be content in its position and with its soil for years. It can tolerate moderate shade, and a plant that has been growing in shade should be slowly hardened off before placing it in full sun, as the plant will be severely scorched if moved too suddenly from shade into sun.

Propagation: It is propagated from seed sown during spring or summer. Germination occurs within 3 weeks, but it can be reproduced by cuttings as well (if available). Flowering can be achieved within 5-8 years.
