Andrea B. Posted July 1, 2013 Share Posted July 1, 2013 Blum, A.G. (2013) Salvia columbariae (Lamiaceae) Chia. Flowers photographed in ultraviolet and visible light. http://www.ultraviol...lumbariae-chia/ Joshua Tree National Park, California, USA05 March 2012Wildflower Pollinator: Bees. Also self-pollinating. Comment:Chia, abundant in the US southwest and Mexican northwest, produces seeds which have medicinal value to many Native American nations. The seeds also have some economic value for novelty planters frequently sold in the US during the Christmas season.Birds, ants and other insects and rodents feed on the seeds. Nectar loving insects visit also. The plant is easily grown, drought tolerant and does not require fertile soil.The dark green, corrugated leaves are quite attractive. The primary marker on the flower is the Visible white ring on the lower lip. In UV, the two-lipped flower shows some moderate to heavy UV-absorbing tonalities with no distinct marks. The stem is UV-bright, so the darker flower cluster does stand out somewhat. Reference:1. Natural Resources Conservation Service (2013) Chia Plant Guide.
