With its feet firmly planted in the water, its long, slender leaves arrayed around a sturdy stalk, and its gently curving petals, the plant’s appearance first suggested an iris: a beautiful if somewhat puzzling version of the irises native to Texas.
In fact, I’d come across Canna glauca, a member of the Canna family native to Texas, Louisiana, Florida, and South Carolina in the United States. The plant favors a wet environment, and often goes by the names water canna, or Louisiana canna. The specific epithet glauca refers to its blue-green leaves.
I’ve never been a fan of so-called canna lilies, which aren’t lilies at all, but members of a genus which originated in tropical areas of the Americas before being introduced into other parts of the world. But C. glauca, less frowsy than many canna cultivars, caught my eye with its color and simpler form.
