Lobelia cardinalis 100 Seeds – Cardinal Flower Heirloom Non-GMO Red Native Pollinator Plant

Lobelia cardinalis, commonly known as Cardinal Flower, is a striking native perennial prized for its brilliant scarlet-red blooms. This heirloom, non-GMO variety brings vibrant color to rain gardens, pollinator gardens, and moist woodland edges. Its tall spikes of tubular flowers are a favorite of hummingbirds and butterflies, making it an excellent choice for wildlife-friendly landscapes.

Cardinal Flower typically blooms from mid-summer to early fall, providing a late-season nectar source.

Planting & Care

Sow seeds indoors 8-10 weeks before the last frost. Press seeds lightly into the soil surface; do not cover, as light aids germination. Keep soil moist and maintain a temperature of 65-75°F. Germination typically occurs in 14-30 days. Once seedlings have several true leaves, transplant into individual pots and harden off before moving outdoors after the danger of frost has passed.

Choose a planting site with moist, well-drained soil. Water regularly to keep the soil consistently moist, especially during dry spells. Apply a layer of mulch to retain moisture and suppress weeds. Deadhead spent flowers to encourage additional blooms. In colder zones, provide winter mulch for protection. Divide clumps every 2-3 years to maintain vigor.
