Gomphocarpus sinaicus
Sinai Milkweed
The Gomphocarpus sinaicus, or Sinai Milkweed, is a hardy perennial plant native to arid and semi-arid regions of the Sinai Peninsula and surrounding areas in the Middle East. Known for its erect, branching stems, narrow green leaves, and small, star-shaped cream or pale green flowers, this plant thrives in harsh, rocky environments. It grows up to 1 metre tall and produces characteristic inflated seed pods, which contain silky seeds that are dispersed by wind.
This drought-tolerant plant is an important species in desert ecosystems, offering nectar for pollinators and serving as a larval host for butterflies.
