Lobelia, Perennial Plant Features
Commonly called cardinal flower, perennial lobelia is a super-easy North American native plant, especially if you have wet, swampy soil. Although it will grow in almost any sunny or partially sunny spot, perennial lobelia likes to have its feet wet so it's the perfect choice for low spots in your landscape that collect water after a rain. Perennial lobelia develops eye-popping, bright red flowers that attract droves of hummingbirds and butterflies throughout the summer. And add extra interest by scoping out varieties that have rich bronze or purple foliage throughout the growing season. The plant grows 18 to 24 inches tall and is relatively deer resistant.
