In summary, what you need to know:
Name : Deuterocohnia ( Abromeitiella )
Family : Bromeliaceae
Type : Perennial
Height : 0.10m to 0.50m
Exposure : Sunny
Soil : Dry, drained, stony
Foliage : evergreen – Flowering : Winter
These plants reveal rosettes of more or less large, more or less thorny leaves. They form cushions, which are found in high mountains or in very dry regions.
Deuterocochnia require very dry soil , they even grow on rocks. Very sensitive to humidity, they can withstand temperatures down to -5°C if they stay dry. Give them a very sunny spot.
> Deuterocochnia in the ground
The planting of Deuterocohnia preferably takes place in spring or summer.
- Plant your Deuterocohnia in a mixture of pebbles/gravel, sand and very light soil
- Water very lightly just after planting.
- This plant tolerates fine substrate very well.
- In France, planting in the ground is only possible in the Mediterranean region
> Potted Deuterocochnia
- Choose a rather low and wide container
- Fill it with a mixture of light potting soil, sand and gravel
- Plant your Deuterocohnia and place it in a sunny location
- Water lightly
> Multiplication of Deuterocohnia
To propagate Deuterocohnia , the simplest way is to carry out a division of the rosettes . This plant forms a multitude of small rosettes of fatty leaves. Simply separate the rosettes and replant them to multiply. Choose rosettes where you can see the development of the roots.

Maintenance of Deuterocohnia
Water the Deuterocohnia regularly during the summer, but sparingly. Preferably use rainwater and always let the substrate dry well between each water supply. Fertilize only once a year in the spring.
> Maintenance of Deuterocochnia in a pot:
In winter indoors, if it is hot, just mist the plant. Remember to repot the plant as soon as the rosettes overflow the pot. Starting in May, you can take your Deuterocohnia outside, placing it in a warm, sunny spot.
Deuterocohnia sometimes suffer from root rot. This happens when the substrate is too wet . Except in dry areas, it is better to grow this plant in a pot , in order to bring it indoors during the winter. When you take it out in the spring, the ideal is to place it under a pergola, or any other garden shed.

Varieties of Deuterocohnia
- Deuterocohnia brevifolia (Abromeitiella brevifolia ): rosettes of 3-5cm green leaves spotted with white, the plant reaches up to 80cm in diameter. It forms small clusters of very discreet flowers. Withstands down to -4°C in dry soil.
- Deuterocohnia lorentziana (Abromeitiella lorentziana ): The leaves of the rosettes do not have lateral spines, they reveal a gray-blue tint. This species reaches 30cm to 60cm in height and offers yellow and green flowers, 2-3cm long. Tolerates -4°C in dry soil.
- Deuterocohnia longipetala (Abromeitiella longipetala ): The leaves of this species also sport a gray-blue color, but the edges are prickly. Another notable difference is that the rosette tufts grow to 60cm tall and produce a spectacular inflorescence up to 120cm long. This long yellow flower particularly highlights the bluish foliage.
- Deuterocohnia chrysantha (Abromeitiella chrysantha ): this species is distinguished by its large rosettes 20cm in diameter. With prickly edges, it is colored a light red, counterbalanced by a yellow flower, which resembles that of the longipetala species.
