Senna Meridionalis Dwarf
Senna meridionalis dwarf (formerly Cassia meridionalis), commonly known as the Succulent Cassia or Taraby, is a rare, pachycaul deciduous shrub endemic to the arid spiny forests and limestone plateaus of southern Madagascar. Highly coveted by caudiciform and bonsai collectors, it naturally forms a fat, gnarled stem with a dwarf, tree-like habit even as a seedling.
Key Characteristics of Senna Meridionalis Dwarf
-
Natural Bonsai Habit: Features a swollen, water-storing trunk (caudex) and thick, zigzagging branches that give it an ancient, miniature tree appearance.
-
Nyctinastic Foliage: Produces delicate, pinnate leaves with tiny leaflets that naturally fold shut at night or when under drought stress.
-
Bright Yellow Blooms: Under strong light, mature plants bear bright yellow, buttercup-like flowers during the summer growing season.
Cultivation & Care Highlights
| Parameter | Care Requirement |
| Light | High light to full direct sun. Maximum sunlight is required to maintain compact growth and trigger flowering. |
| Substrate | Highly porous, gritty mineral mix (70–80% pumice, perlite, lava rock, and coarse sand with 20% organic compost). |
| Watering |
Summer: Water thoroughly once the soil dries completely; it can take frequent watering when actively leafed out.
Winter: Cut back drastically as leaves drop. Keep almost completely dry during dormancy to prevent caudex rot. |
| Temperature | Heat-loving. Maintain above 12°C–15°C (54°F–59°F); protect strictly from freezing. |
