Although not native to the US, originating in South America (Brazil and Argentina), glandularia pulchella has been established in many southern USA states. Clusters of bright purple flowers are produced during spring and summer, borne at the end of short stalks. Each contains several dozen components; five-lobed flower heads with whitish centers, a little less than one inch in diameter. The plant has dense clumps of narrow, finely divided leaves, and grows quite close to to the ground.
