The flowering plant genus Canna has nothing to do with cannabis: in spite of the amazing name similarity, the flowering, lily-like plant is not related to the intoxicating hemp plant.

Canna, also called flower tube, are the only plants of the genus Blumenrohrgewächse (Cannaceae) and belong to the family of ginger plants. We introduce you to the colorful tropical plants for your garden.

The canna plant in detail

Canna have, similar to lilies of the valley, no tuber, but a so-called rhizome. From this, in some species, leaves of up to five meters in size develop on so-called "pseudo-stems": these are actually made of rolled leaves, but can reach great firmness.

The flowers are very noticeable, in Canna indica (also called "Indian flower tube") deep red and very large. Because of their splendid coloring and size they are very popular, since 1530 one knows the plant in Europe. Below the flower is the seed of the plant: it is kept in small, soft prickly ovaries. The propagation of the plant in a natural way is quite special and is carried out by pollinating insects. The rhizome in the root region of the cannabis plant is compact and similar in size to a potato.

Canna rhizomes are not winter proof: they must be stored in a cool and dark place in winter frost-free. In the spring, as soon as no more frost is expected, the plants can be put back into the soil.

When you want to enjoy the blossoms of the "Indian flowerpipe", you can certainly influence: plants that have been driven forward from January, which can prepare for application in warm and bright locations, bloom already in spring and keep this flower very long. If planting takes place only after the last night frosts in early May, you will have a beautiful flowering flower in late summer.

Ideal location and optimal care

The choice of location and care for cannabis plants is not particularly difficult. Due to their tropical origin, the plants can be planted in the blazing sun, the location must be very bright. The water supply should be regular, on hot summer days every evening.
