Rumex rothschildianus (also known as Rumex aeroplaniformis) is a small dioecious annual, extremely rare, and endemic to the central coastal plain of Israel. It survives in only a few populations along the Sharon coastal strip.

The plant was first discovered by Aaron Aaronsohn in 1906, who named it in honor of Baron Edmond de Rothschild. Its second name comes from the resemblance of its fruits to little airplanes. The coastal dune vegetation plot is part of the Noah Naftulski garden of Israeli flora. Many of the plants in this collection have been defined as "Red-list species", endangered due to massive development and habitat degradation, including Rumex rothschildianus. At the beginning of December hundreds of seeds of Rumex rothschildianus were sown in both the Garden's nursery and in the coastal dune plot.
The TAU Botanical Garden preserves more than half of the known Israeli endangered plants. They are part of the Garden’s plant exhibitions and used to educate toward the conservation of biodiversity. Our goal is to maintain a stable population that can be reintroduced back into nature when needed. You are invited to observe the seedlings during the winter and enjoy their unique blossom in the spring.
