Yes, the spiral cactus does flower, producing showy large flowers.
Understanding the Spiral Cactus and its Flowers
The plant commonly known as the spiral cactus is Cereus forbesii 'spiralis'. This specific variety is recognized not only for its unique twisted stems but also for its ability to produce beautiful blooms.
As stated in the reference, Cereus forbesii 'spiralis' are large, hardy, shrub-like cacti with showy large flowers.
These flowers are typically quite striking and add significant ornamental value to the plant when they appear.
Characteristics of Spiral Cactus Flowers
While the specific timing and appearance can vary slightly depending on climate and growing conditions, the flowers of the Cereus forbesii 'spiralis' generally share common traits with other Cereus species:
- Appearance: They are described as "showy large flowers." Cereus flowers are often white or creamy, sometimes with hints of pink or green, and are known for their size.
- Blooming Time: Many Cereus species are night-blooming, with flowers opening in the evening and closing by morning. This is a common trait for cacti adapted to arid environments, as it reduces water loss during pollination.
- Fragrance: Cereus flowers can be quite fragrant, especially at night, attracting nocturnal pollinators like moths or bats in their native habitats.
Encouraging Flowering
To encourage your spiral cactus to flower, ensure it receives:
- Plenty of sunlight (at least 6-8 hours daily).
- A proper dormant period during winter with cooler temperatures and reduced watering.
- Appropriate watering during the growing season (allow soil to dry out completely between waterings).
- Well-draining soil.
By providing suitable conditions, you increase the likelihood of your Cereus forbesii 'spiralis' rewarding you with its impressive large flowers.
