‘Zamnesia’ – Trichocereus bridgesii hybrid – Semi Monstrose – Cuts

Zamnesia History

This clone was sourced from Zamnesia and is one of their offered clones. Zamnesia is a weird plant. Clear bridge genetics but an uncommon bridge spine formation. Zamnesia are not very forthcoming with exact genetic lines, but may well be a bridge dominant x pachanoi cross.

One thing is certain, its a weird and wonderful plant :-).

Watering

Watering from Spring (April) to the beginning of Autumn (End of September). Depending on what kind of summer we get will depend on how frequently you need to water, but, less is better with cacti. During the winter months, little to no watering is required or the roots could rot (they do not like to be wet for long periods).

Substrate

In warmer climates, you could go for a more nutrient-rich mixture (50% organic / 50% inorganic). But, in the UK, it is best to err more on the side of inorganic (60% – 70% inorganic) to ensure the pot is drained quickly.

Locality

Trichocereus bridgesii is native to Bolivia, where it grows in the dry Andean valleys.

History and Taxonomy

The species was originally published as Cereus bridgesii by German botanist Joseph zu Salm-Reifferscheidt-Dyck, usually cited as Salm-Dyck, in 1850. His original account records that English botanist and plant collector Thomas Bridges brought the plant from Bolivia in 1846. The name bridgesii was given in his honour. Britton and Rose transferred the species to the genus Trichocereus in 1920, creating the familiar name Trichocereus bridgesii. Following the later reclassification of Trichocereus into Echinopsis, the species became Echinopsis lageniformis. It could not be called Echinopsis bridgesii because that name had already been used for a different Bolivian cactus. Echinopsis lageniformis is the currently accepted botanical name, although Trichocereus bridgesii remains firmly established among growers and collectors, many of whom still refuse to bow to the great Echinopsis takeover!
