Description
The Canna lily produces wide, often reddish‑brown veined leaves and bright flowers in red, orange, or yellow, adding an exotic accent to beds. Native to tropical America, it thrives best in wet garden beds near ponds or as a striking container plant on terraces. Flowers appear from July to September, attracting bees and other pollinators. The plant is heat‑loving and cannot tolerate frost; its rhizomes require a frost‑free winter location.
Care instructions
Plant the rhizomes after the last frost (around mid‑May, week 20) in a sunny, sheltered spot. Cannas are thirsty and appreciate nutrient‑rich, moist soil; in wet beds or containers they can receive slightly more water. Remove spent flowers regularly to extend blooming into autumn. Before the first frost, dig up the rhizomes, clean them, and store them cool and dry at about 5–10 °C over winter—e.g., in a cellar in a box with slightly damp substrate. Varieties such as ‘Durban’ with variegated foliage also need the same winter care.
