About Pale-Spiked Lobelia: This plant’s genus name of Lobelia honors Flemish botanist Mathias de Lobel, who studied medicinal uses for plants. The species name “spicata” means “spiked” and refers to the slender stems.
Pale-Spiked Lobelia Germination: Direct sow in late fall, planting on the surface of the soil since these seeds need light to germinate. For spring planting, mix the seed with moist sand and store it in the refrigerator for 60 days before planting. To start indoors, sow the seed 6-8 weeks before the last frost of spring and keep the soil lightly moist until germination. Transplant the seedlings as soon as they can safely be handled and there is no chance of frost.
Growing Pale-Spiked Lobelia Seeds: Keep seedlings well watered and control weeds. These plants appreciate moisture, but also grow well in average soil. To encourage bushier growth, pinch back the stems before they bloom. These plants may self-sow in good growing conditions. Mature plants can be divided in early spring. These flowers attract hummingbirds and butterflies, and flourish near ponds or streams.
Harvesting Pale-Spiked Lobelia: These blossoms do not perform well as cut flowers, and are best enjoyed outdoors.
Saving Pale-Spiked Lobelia Seeds: As soon as the flowers fade, watch the seed heads carefully since the tiny seed can easily blow away in the wind. Shake the seed heads over a container to remove the ripe seed; repeat until all the seed has ripened. Store the cleaned seed in a cool, dry place.
