Mexican Lobelia

Lobelia

Cardinal Flower

In the dog days of August, just when the border is not looking so lively, this genus of colorful, stately selections rejuvenates the garden with spectacular leafy flowering spires, attracting crowds of eager hummingbirds. Perfect in meadow plantings, these sturdy herbaceous perennials appreciate a well drained site, a light winter mulching, rich, moist soils and partial shade in warm climates, except for Lobelia tupa and Lobelia laxiflora, which like it hot and on the dry side.

<i>Lobelia laxiflora</i>

A lush-looking, bushy perennial capable of enduring considerable neglect, this impressive Lobelia plays host to festive bicolored blooms. Spreading by underground rhizomes, a close thicket of slender, yet sturdy, red-tinted stems strikingly set off narrow and lustrous, pointed green leaves that extend 2 to 4 in. Slim, 2 in. long red tubes are loosely clustered at shoot tips, while each bright-hued flower flares to reveal a sunny yellow throat.

Hailing from Arizona and Mexico, the Mexican Lobelia entices gardeners and hummingbirds alike with nectar-rich blossoms, can tolerate some shade, but looks its best in sunny, dry sites and has been reputed to possess anti-inflammatory alkaloids.

Blooms June–September.

Size: 2' 0" – 2-1/2' high x 2' 0" – 3' 0" wide.

Hardy to zone 8.
