Appearance

It is a perennial herbaceous plant that grows up to 1.2 m tall and is found in wet places, streambanks, and swamps. The leaves are up to 20 cm long and 5 cm broad, lanceolate to oval, with a toothed margin. The flowers are usually vibrant red, deeply five-lobed, up to 4 cm across; they are produced in an erect raceme up to 70 cm tall during the summer to fall. Forms with white and pink flowers are also known.

''Lobelia cardinalis'' is related to two other ''Lobelia'' species in to the Eastern United States, ''Lobelia inflata'' and ''Lobelia siphilitica'' ; all display the characteristic "lip" petal near the opening of the flower and the "milky" liquid the plant excretes. ''L. siphilitica'' has blue flowers and is primarily pollinated by bees, whereas ''L. cardinalis'' is red and is primarily pollinated by the ruby-throated hummingbird .

Naming

It was introduced to Europe in the mid-1620s, where the name ''cardinal flower'' was in use by 1629, likely due to the similarity of the flower's color to the vesture of Roman Catholic Cardinals.

Habitat: Pond side: I rarely see this wildflower, and this patch is now gone. It was bulldozed when the small pond that it grew beside was dredged to eradicate invasive fish and plants.  Unfortunately, the workers were not that careful and destroyed the habitat surrounding this pond.
