Lobelia cardinalis, commonly known as Cardinal flower, is a herbaceous perennial plant native to North America. It is named for its vibrant red flowers that resemble the color of a cardinal's robe.
The Cardinal flower is a popular choice for gardeners due to its striking appearance and ability to attract pollinators like hummingbirds and butterflies. The plant typically grows to a height of 2 to 4 feet (60 to 120 centimeters) and features lance-shaped green leaves. In late summer to early fall, it produces erect spikes of tubular flowers that are primarily bright red in color, although there are cultivars with pink or white blooms as well.
The flowers of Lobelia cardinalis are known for their intense color and can create a stunning display in a garden or landscape. They are typically arranged densely along the flower spikes and provide a vibrant contrast against the surrounding foliage. The plant prefers moist to wet soil conditions and thrives in partial shade to full sun.
Lobelia cardinalis is often used in perennial borders, woodland gardens, or near water features such as ponds and streams. It is a relatively low-maintenance plant, but it may require regular watering, especially during dry periods, to ensure optimal growth and flowering.
