Canna, a perennial.

I don't know about propagating them from seed. They might not bloom the
same color. Flowers come in white, yellow, gold, orange, red, and
combinations of those. Leaves might be green or variegated with red or
yellow.

I would strongly recommend buying plants from a nursery, but only when
they are in bloom. Otherwise, you will not really know what flower
color they will have.

Cannas do okay in temperate climates where the soil does not freeze.
They do best in climates with hot summers and mild winters. They
require full sun, regular irrigation, and rich loose soil.

Actually, I am not fond of cannas because I don't think they are
attractive when not in bloom.



There are some with superb leaf colour that do look exceptional in leaf
especially if they are planted so the sun shines through the leaves.
Pretoria is probably the most common of those but there are better forms
available with red, yellow and orange stripes.
Yet others like C. musifolia are grown just for their leaf shape and colour
, as the name suggests they look like bananas, and those you certainly don't
want to flower as it spoils the effect.
