It is very unusual to see such an Euphorbia obesa.
plants are very nice sculptures one
different to each other. There are also plants that show the classical
polytomy at the same time.
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.
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 -5°C (-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
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.
