Its red and green flowers appear at the end of long stalks between August and November. The flowers display in a sequence from the lowest point, those following are in a progression of development. The spent flower-stalks may remain well after their season. The length of these stalks from the base is up to 1200 mm tall.

Cultivation

The species germinates readily from seed. As plants generally deteriorate after the second season, they are best treated as a biennial
Biennial plant
A biennial plant is a flowering plant that takes two years to complete its biological lifecycle. In the first year the plant grows leaves, stems, and roots , then it enters a period of dormancy over the colder months. Usually the stem remains very short and the leaves are low to the ground, forming...

. They are dormant in the summer, and watering should be withheld during this period. They are susceptible to the fungal ink spot disease and the leaves are attractive to snails. They are often used as cut flowers, due to their unique appearance and lasting qualities.
