Description

Lobelia cardinalis, commonly known as Cardinal Flower, is a stunning native perennial plant found in the eastern and central parts of North America. This remarkable plant typically reaches heights of 2 to 4 feet (60 to 120 cm) and is celebrated for its striking scarlet-red, tubular flowers that are arranged in tall spikes. These vibrant blossoms are a magnet for pollinators, especially hummingbirds and butterflies, with their vivid hue and nectar-rich rewards. Cardinal Flowers feature lance-shaped, deep green leaves that provide an attractive backdrop to the brilliant blooms. They thrive in moist to wet soil and are often found along the edges of streams, ponds, and in other damp, low-lying areas. With its dramatic appearance and ecological importance as a pollinator attractor, Lobelia cardinalis is a favorite among gardeners looking to add a burst of color and wildlife interest to their gardens, particularly in the late summer and early fall when it comes into full bloom.  Zones 3-9 

Germination

Germinating Lobelia cardinalis seeds can be an exciting endeavor. To break the seeds dormancy, consider cold stratification, which mimics the natural winter conditions they require. Place the seeds in a damp paper towel or peat moss, then seal them in a plastic bag and refrigerate for 6-8 weeks. After stratification, sow the seeds in a seed tray or pots filled with a well-draining, moist seed-starting mix. Lightly press the seeds onto the surface of the soil; they need light to germinate, so do not bury them. Place the tray or pots in a location with indirect sunlight or under grow lights, maintaining a temperature around 65-70°F (18-21°C). Keep the soil consistently moist, either by misting or using a bottom-watering method. Germination can be slow and irregular, taking anywhere from a few weeks to several months. Once the seedlings have grown large enough to handle, transplant them into individual pots or directly into the garden, ensuring they receive adequate moisture and partial shade as they establish themselves. Be patient, as growing Lobelia cardinalis from seed can take time and careful attention, but the vibrant red flowers and their value to pollinators make it a rewarding choice for any garden.
