Description

  • Perennial
  • Pelargonium tetragonum is a rare and unusual semi-succulent shrub native to the dry, rocky regions of the Cape Provinces in South Africa.
  • Because of its unique adaptations, Pelargonium tetragonum thrives in the same conditions as cacti and succulents – it is not a typical bedding geraniums.
  • It is highly sought after by plant collectors for its unique, architectural growth habit that closely resembles an Euphorbia rather than a traditional geranium.
  • Pelargonium tetragonum is distinguished by its almost leafless, green three- to four-angled, jointed and succulent stems.
  • When present, the leaves are fleshy, palm-shaped and sometimes have red zonal markings.
  • It bears large delicate cream to pink flowers from September to December that look like butterflies at the tips of the stems.
  • If supported by other vegetation, it will reach a height of 2 m.
  • Keep in full sun to bright, direct light to maintain its rigid stem structure and promote optimal flowering.
  • It needs well-draining soil and water sparingly during the warm growing season, allowing the soil to dry out completely between watering cycles.
  • The leaves are often dropped during dry periods to conserve water.
  • In the winter, keep the plant almost entirely dry to prevent root rot.
  • Pelargonium tetragonum handles pruning well and can be trimmed back after flowering to manage its gangly habit.
  • It is easily propagated by taking softwood stem cuttings, allowing them to callously dry for a day or two, and rooting them in damp river sand.
