Astragalus aquariensis is a perennial herb 6-12in. tall with spikes of vibrant yellow flowers that bloom late June-August. It is endemic to Utah and likely somewhat parasitic.
As of 2006 this species was no longer listed as a candidate because a recent survey found more individuals than previously and there is no evidence of factors that might impact the species as posing a threat. The increase of individuals may be attributed to studies that have shown this species trends are potentially linked to the weather, and specifically to precipitation.
