(Sierra Madre Cardinal Flower) Butterflies and hummingbirds love the long, scarlet and orange trumpet blossoms of this Lobelia native to the Sierra Madre Occidental Mountains of Southern Arizona and Northern Mexico.

Mexican Cardinalflower is another common name for Sierra Madre Cardinal Flower. In its scientific name, the term laxiflora refers to the looseness of this long-blooming, clump-spreading plant's flower stems. Angustifolia concerns the narrowness of its shiny leaves.

The Lobelia genus is named for French botanist and herbalist Matthias de l'Obel (1538-1616) who served as physician and botanist to Britain's King James I.

Sierra Madre Cardinal Flower triples in height when in bloom. It grows well in full sun to partial shade and tolerates heat. Although it thrives with average watering based on local conditions, this beauty also tolerates drought. It is perennial in a broad range of zones and, due to rapid growth, is a good bedding plant in areas with frigid winters. Plant it in rich soil.
