Plant Guide: Canna lily
Canna x generalis, commonly known as Canna lily, is a warm-weather herbaceous perennial with a bold, tropical look. Its broad leaves, colorful flowers, and tall stature make it a great focal point or accent in landscapes. Native to the southern regions of America, it thrives in tropical and subtropical climates, is very hardy in proper zones, and requires minimal maintenance. In addition to its visual appeal, it attracts pollinators and supports ecosystem health, making it popular in horticulture. The name Canna comes from the Greek word “Kanna,” meaning reed-like, referring to its long stem. In the past, its rhizomes were harvested for their high-quality starch and used to make noodles, but it became less common as crops like potatoes and corn gained popularity. Its hard, round seeds were once used in India as shotgun pellets, giving it the nickname “Indian Shot.” Today, it is primarily grown for ornamental purposes, with over 2,000 unique cultivars available. Canna lilies grow well in warm, humid climates and belong to the Cannaceae family. They spread through rhizomes and can grow 6–16 feet tall and about 2–3 feet wide. Their large, elliptical leaves (18–36 inches long) are usually green, though some cultivars feature purple or red tones. Flowers bloom in spikes at the top of the stalk and vary in color, sometimes displaying spots or stripes. Hardy in USDA zones 8–11, Canna lilies also provide environmental benefits, including stormwater pollutant removal, but are most valued for their striking appearance and vigorous growth.
