Cardinal Flower

The Cardinal Flower, scientifically known as *Lobelia cardinalis*, thrives in wet, marshy environments and along stream banks. As a wetland wildflower native to North America, it prefers consistently moist soil and can even tolerate shallow standing water, making it unsuitable for dry, arid gardens.

Yes, the plant is famous for its prominent, bright red flower spikes which act as a massive magnet for hummingbirds during the summer blooming season. The deep tubular shape of the red flowers is perfectly evolved to accommodate the long beaks of hummingbirds, making it a vital nectar source for them in North American ecosystems.

Yes, like many plants in the *Lobelia* genus, the Cardinal Flower contains toxic alkaloids that can cause severe digestive distress if ingested by humans or pets. While Native American communities historically used very small, highly controlled amounts of the roots and leaves for medicinal purposes, it should generally be considered poisonous for casual consumption.

To successfully overwinter *Lobelia cardinalis*, you must ensure the plant's crown does not freeze completely, which is why a thick layer of mulch is highly recommended in colder northern climates. Because it naturally grows in wetlands, maintaining moist, unfrozen soil around the roots during the winter months is critical for the plant to survive and regrow the following spring.
