Canna

Canna have mostly annual foliage which emerges from perennial, fleshy, usually winter dormant rhizomes. They are strong and fast growers for any rich, leafy and slightly moist soil. All are very ornamental due to their large, banana-like foliage and clusters of funnel-shaped flowers in summer. Wild species naturally make smaller and more elegant flowers. Please note that taxonomy (= botanical naming) in this genus is in a complete mess and there are uncountable invalid names as well as hybrids which are traded as species and vice-versa. We try our best to keep botanical names and identification as accurate as possible, but we cannot give any guarantee. What we do guarantee is that you will receive seeds of exactly the plants as shown in our photos!
Prior to sowing scarify seed (e.g. carefully scratch the seed coat with fine sandpaper) and soak them in luke warm water for some 48h. Sow at a minimum of some 20°C in any rich soil. Will start to flower the second year. In most species rhizomes can be unpotted in autumn as soon as foliage has started to yellow. Store rhizomes in a dry, cool and frostfree spot until the end of spring. The tallest species, such as Canna paniculata and Canna tuerckheimii, are best grown as evergreens at a winter minimum of some 15°C, for their shoots will usually need 4 to 6 months to start flowering.

Canna altensteinii

Canna altensteinii

200 (280)cm, an ornamental, very tall species with large leaves and terminal racemes with orange flowers. By some authors it is regarded a member of the Canna indica complex, however, Canna altensteinii is clearly distinct. It grows much taller in all aspects and is more similar to the Giant Canna (Canna tuerckheimii). Easily grown in humus rich soil in a sunny spot throughout the year. In winter keep plants at a minimum of some 15°C and reduce watering to a minimum. At lower temperatures plants will go dormant and the rootstock will stay dormant during the cold season. VII-X.

Canna compacta

Canna compacta

160 (200)cm, has elegant broad, banana-like leaves and branching inflorescences with quite large, showy orange-red flowers with a yellowish inner stripe. For any rich, humus rich soil in a sunny spot in summer. Identity of this clone is uncertain. Our plants are seed raised, and all plants are identical and readily set viable seeds. Thus we believe them to be a pure species strain. VI-IX.

Canna flaccida (Golden Canna)

Canna flaccida (Golden Canna)

150cm, Golden Canna or Bandanna of the Everglades is native in wetlands from south-eastern to south-central USA. It makes broad lanceloate, yellowish-green leaves and showy, rather large, pale yellow and lightly perfumed flowers which open in the evening and fade away around noon the following day. It is the most widely used parent in large-flowered hybrid cannas. However, the pure species is rarely known in cultivation. Easily cultivated in any humus rich, always moist soil in a sunny spot during summer. In winter keep the dormant, fleshy rhizomes rather dry in a cool, yet frost free spot. Several companies falsely offer seeds from Canna indica var. flava under the name of Canna flaccida. We provide seeds from the true and unhybridized species. VI-VIII.
