Senecio globosa is one variation of Senecio articulatus (=hot dog or candle cactus). Many times it is also referred as Senecio articulatus v. globosa. The globosa’s jointed segments are more rounded compared to those of the articulatus species.
Not much information about this rare succulent. There are many different species of Senecio plants and mostly are native to South Africa and Madagascar. Just like any other cacti and succulents, S. globosa has to kept drier during winter months and moderate watering during warmer months.
Nothing really spectacular about this dainty plant except the odd shape and the interesting leaves are quite pretty. The small globular stems seem to be stacked in a precarious way that you may be afraid they are going to fall. Ha, ha…… I read somewhere that this plant has flowers, so I cannot wait to see mine flowering.
Update January 18, 2012:
Senecio globosa is supposed to drop leaves in the winter time, but here in Melbourne is summer now and ours is still bare. Some new growths are not round, instead they are long/more like cucumber. Weird! So far I have moved the plant into a better pot.
