Euphorbia razafindratsirae

OriginEuphorbia razafindratsirae is endemic to Madagascar, specifically found in the Toliara province. It was officially described in 1998. It is named in honor of the Razafindratsira family, renowned Malagasy botanical collectors.

Habitat In its natural environment, this species thrives in dry deciduous forests and spiny thickets. It is typically found growing in sandy or rocky soils. It is well-adapted to the semi-arid climate of southwestern Madagascar, where it utilizes its succulent stems to survive prolonged dry periods.

DescriptionEuphorbia razafindratsirae is a slow-growing, highly branched succulent shrub prized for its intricate and defensive "thicket" appearance.

• Growth Habit: It forms a compact, densely branched shrub that can reach up to 1 meter in height. The branching is often very tight, creating a bird-nest or cage-like structure.

• Stems: The branches are slender, cylindrical, and dark green to grayish-brown. They are relatively thin, usually measuring only a few millimeters in diameter.

• Spines: The stems are heavily armed with thin, needle-like spines. These spines are derived from modified stipules and are arranged along the stems, providing the plant with a fierce, "armored" texture.

• Foliage: The leaves are small, narrow, and concentrated at the tips of the new growth. They are deciduous and will drop off during the dry dormancy period to conserve moisture.

• Flowers (Cyathia): It produces small, subtle greenish-yellow flowers (cyathia) at the branch apices.

• Cultivation: This is a connoisseur's species that requires full sun to bright light to maintain its dense branching habit. It necessitates a well-draining mineral substrate and must be kept warm and mostly dry during the winter.
