URARIA CRINITA
If I remember correctly, we received this Uraria crinita (synonyms: Doodia crinita Roxb., Hedysarum crinitium L.; common name: Asian Foxtail; Family Fabaceae) plant from a donor and displayed this during the GardenTech in 2009. Since then, we managed to propagate this plant from the seeds.
The plant sends up erect spikes of small pinkish flowers that open gradually from the base to the tip. 2 links are shown below:
