Lobelia siphilitica var. alba, commonly known as Great White Blue Lobelia or White Cardinal Flower, is a stunning perennial that elevates the elegance of any garden space. Renowned for its pristine white, 1-1/2 inch tubular flowers, this variety adds a splash of luster to shaded garden corners that cloister from the scorching afternoon sun, while harmonizing boldly with vibrant summer hues. Ideal for garden borders, its tall flower spikes bloom later than the L. cardinalis, typically from July to September, ensuring a long and captivating display of beauty. Growing to a height of 24 to 36 inches with a spread of 15 to 18 inches, it thrives best in moist to wet, well-drained soil under full sun, although it tolerates light and partial shade. An award-winning choice for eco-conscious gardeners, this deer-resistant plant attracts a flutter of butterflies and hummingbirds while being tolerant of clay soil and occasional periods of drought. Native to North America, White Cardinal Flower shines in mass plantings and general garden use, flourishing vividly in hardiness zones 4 through 9.
