A new chapter in our ongoing work in selection and research
Dionaea muscipula has always been at the heart of our work at Diflora. It was not only the first species we successfully hybridized, but it continues to represent a genetically fertile and remarkably stimulating field of research. Despite being a single species, Dionaea displays a wide range of distinct phenotypic (visual) forms, a characteristic that allows us to obtain, through targeted crosses, plants with surprising and highly distinctive traits.
Today, we are pleased to share an announcement that marks a true milestone for Diflora. With great satisfaction, we announce that six of our exclusive Dionaea muscipula hybrid creations—born from patient selection and crossbreeding in our laboratories—have been officially registered as new cultivars by the ICPS (International Carnivorous Plant Society), the international authority responsible for carnivorous plant registration.
ICPS: The Seal of Botanical Validation
Founded in 1972 in the United States, the International Carnivorous Plant Society is the global registration authority for all carnivorous plant cultivars. Its role makes it the international reference point for nomenclature and varietal description.
Why Registration Matters
- Official Naming: Registering a cultivar, followed by its publication in the quarterly Carnivorous Plant Newsletter, grants validity and official recognition to the name associated with a specific plant.
- Genetic Traceability: The ICPS registry ensures that a fantasy name (for example, ‘Fiamma’) is permanently linked to the plant’s detailed description and its distinctive genetic traits.
- Standardization: For enthusiasts, collectors, and experts, registration acts as a standard. It guarantees that any plant sold under that name carries the precise phenotypic characteristics defined by its creator.
This recognition rewards our consistency in research, our care in selection, and the meticulous dedication invested in our breeding program. Diflora’s goal is to continue submitting official descriptions for all our cultivars that stand out significantly for their unique traits.
The “Made in Diflora” Genetic Heritage: Our Six Newly Registered Cultivars
Our six new cultivars, the result of complex hybridizations, present a spectrum of characteristics ranging from trap morphology to coloration, including rare structural mutations.
Dionaea muscipula ‘Fiamma’
A prostrate hybrid, ‘Fiamma’ stands out for its abundance of sensitive hairs on the lobes. Its coloration is the essence of its name: a gradual transition from pale yellow to very dark red, almost black, evoking the image of an intense flame. This cultivar is closely related to ‘Carboni Ardenti’, yet unmistakably different thanks to the dark spotting near the trigger hairs and its long, crossed, markedly irregular teeth. It is the true jewel of our collection for its sophisticated and dramatic coloration.
Dionaea muscipula ‘Fuego Radioactivo’
‘Fuego Radioactivo’ is pure chaotic energy. This cultivar was selected for its large traps—often flattened against the substrate—and for its intense red coloration with pronounced striping and internal spotting. Its elongated shape recalls ‘Louchapatès’, but what makes it unique is its unpredictable dentition: curved, distorted teeth of variable length, arranged in a disorganized pattern that can even begin deep within the lobe. The overall effect strikingly resembles the distorted, chaotic flames of a nuclear explosion.
Dionaea muscipula ‘Phyllopterix’
A giant cultivar with an unusually shaped trap morphology. Its name is inspired by Phyllopterix, a genus of marine fish known as sea dragons. Its defining feature is the presence of multiple traps—often cup-shaped and deformed—fused together into a single complex leaf connected by a single petiole. While it shows similarities to multi-trap forms such as ‘Master of Disaster’ or ‘Mirror’, its composite structure and resemblance to the head and protrusions of a sea dragon firmly establish its uniqueness.
Dionaea muscipula ‘Ruggine’
This cultivar originated from the isolation of a spontaneous Dionaea muscipula mutant. It resembles ‘Scarlatin’, but with longer teeth and a more complex variegation pattern. The name ‘Ruggine’ (Rust) derives from its unique coloration: a variable-intensity red variegation covering the traps, reminiscent of oxidized metal. It is a perfect example of how a single mutation can produce a completely new chromatic effect worthy of registration.
Dionaea muscipula ‘Angry Lettuce’
Born from one of our crosses, ‘Angry Lettuce’ is known for its combination of unique shapes and growth patterns. It incorporates traits from ‘Werewolf’, but with a more elongated, arched, and markedly deformed form. It features aggressive-looking teeth, which inspired the name suggested by our collaborator Helleentje Walker. Young plants display a notable pinkish-red coloration that typically fades to green as they mature.
Dionaea muscipula ‘Twister’
Developed from a cross between ‘Werewolf’ and ‘Dracula’, its defining trait is the spiral shape of its traps—a feature most evident in young leaves and still present, though less pronounced, in mature traps. Its uniqueness is further enhanced by a very rare genetic condition: the absence of trigger hairs inside the lobes. This makes it significantly less reactive in prey capture compared to other Dionaea, but offers a botanically fascinating trait for morphology enthusiasts.
Looking Ahead: Our Commitment Continues
The ICPS recognition confirms the rigor of our selection and propagation process. As Journal readers know, the journey from pollination to the commercial availability of a new clone requires over 24 months of work, including manual hybridization, in‑vitro sowing (cold stratification and micropropagation), and the long acclimatization phase from the heterotrophic laboratory environment to the outside world.
It is precisely during acclimatization that a cultivar’s distinctive traits fully emerge, allowing us to isolate and select the most stable and unique phenotypes.
With the official registration of ‘Fiamma’, ‘Fuego Radioactivo’, ‘Phyllopterix’, ‘Angry Lettuce’, ‘Ruggine’, and ‘Twister’, Diflora not only adds six gems to the Dionaea muscipula landscape and strengthens the prestige of our collection, but also gains renewed motivation to continue our path of research and innovation.
This is only the beginning: our ambition is to keep selecting and submitting to the ICPS all cultivars we consider significantly special and stable. We are pleased to share the link to the official ICPS page in the November issue of the Carnivorous Plant Newsletter, announcing the publication of our new cultivars.
