The floriferous cane, also called canna indica, is a perennial rhizomatous herbaceous plant native to South America; it produces long oval, pointed, rigid, erect leaves, of very decorative color, bluish-green, or green-brown, or even with a margin in a contrasting color. Starting from June-July, until the first colds produce long erect stems, rigid, high up to 120-150 cm, which carry a compact panicles of very colorful flowers, which bloom in succession. The canes generally produce flowers in shades of yellow and red, although there are rosy or salmon-colored hybrids. These rhizomatous plants are very popular in gardens, used mainly in large corner spots, or even in large containers. The fleshy roots tend to widen a lot; it is advisable to remove the withered flowers, so as to prolong the flowering; if you leave the flowers the canes produce long pods containing small roundish seeds, generally fertile.
The species of indica cane are planted in a predominantly sunny, or semi-shaded, place, especially in areas with a very hot and dry summer period; the fleshy rhizomes can withstand short frosts, but in areas with very cold winters they must be sheltered inside during the cold months; they can be cultivated in pots, bringing the containers to a sheltered place in October, or we can eradicate the rhizomes, as soon as the leaves have started to dry; the rhizomes must be cleaned, then placed in fabric bags, mixed with sawdust or shredded bark, to be kept in a dark and dry place. They settle down during the spring season.
In general, the species of flowering reed are satisfied with the rain water as irrigation, although regular watering, to be administered when the soil is dry, promotes a luxuriant flowering and allows to better appreciate all the beauty of these plants; during the month of September the watering is interrupted to allow the plants to go into vegetative rest. From April to August it is necessary to dissolve fertilizer for flowering plants in the water, every 15-25 days to ensure optimal growth of our indica cane plants.
As far as the soil is concerned, we can say that these plants develop without problems even in the common garden soil, but it is advisable to plant them in fertile, well-drained, soft and deep soil to obtain good results of growth of the flowering cane.
For those who wish to prune the plant, it is useful to know that it is not necessary to provide for pruning. The cane indicates it does not need to be cut to develop at its best. It is sufficient to remove the dry or damaged parts so as not to develop diseases or parasites more easily.
The multiplication of the flowering cane occurs in spring by seed, or in autumn by division of the rhizomes.
