Schematic diagram of the structure of the Canna flower
Geographical distribution:
The Canna is native to tropical regions such as America, India, and the Malayan Peninsula, and is distributed in India and various parts of north and south China, growing at altitudes of 800 meters. It has been cultivated artificially and can be grown nationwide, but it is not cold-resistant, and the flowers and leaves wither after frost.
Growth habits:
It prefers a warm and humid climate, is not frost-resistant, and has an optimal growth temperature of 25-30°C. It enjoys full sunlight and fertile soil. In its native region, it does not have a dormant period, growing and flowering throughout the year. It is strong and adaptable, not picky about soil, thriving in moist and fertile loose sandy loam, slightly tolerant to waterlogging. It fears strong winds. Planting in spring, April to May after the frost, the top of the stem forms a flower bud, and the small flowers bloom from bottom to top. During the growing season, the buds of the rhizome continue to sprout and form new stems and flowers, blooming continuously from June to before frost, with a long total flowering period. The rhizome can overwinter in the open in the south of the Yangtze River, while in the north of the Yangtze River, it must be protected artificially to overwinter.
Not cold-resistant, afraid of strong winds and frost. It is not strict about soil requirements, can tolerate poor soil, and grows well in fertile, moist, and well-drained soil. In late autumn, after the plant withers, cut off the aboveground part, dig up the rhizome, dry it for 2-3 days, and bury it in sandy soil in a well-ventilated greenhouse, without watering, keeping it above 5°C for safe overwintering.
Garden use:
The Canna flower is large and colorful, with rich colors and a good shape, easy to cultivate. Many excellent varieties have been bred now, with high ornamental value, suitable for potting or ground planting, decorating flower beds.
Air purification:
The Canna not only beautifies people's lives but also absorbs harmful substances such as sulfur dioxide, hydrogen chloride, and carbon dioxide. It has good resistance, and although the leaves are easily damaged, they quickly grow new leaves after being damaged and recover growth. Because its leaves are easily damaged and sensitive, it is known as the living monitor for detecting harmful gas pollution in the environment. It has the function of purifying the air and protecting the environment. It is an ideal flower for greening, beautifying, and purifying the environment.
