Haemanthus namaquensis.
one of the first Pachypodium gracilius that I purchased, I love this thing.
bad photo, but it took less than a day for this Welwitschia to germinate, and I also checked a few more, and they are also germinating.

A revisit from an article written for The Caudiciform and Pachycaul Society buy the man, Bihrmann himself.
Are you curious about caudiciform plants? This term often sparks debate among plant enthusiasts and collectors. Originally, the Latin word ‘caudex’ referred to a plant’s stem. ‘Caudiciform’, meaning stem-like, refers to plants forming a structure akin to a stem, such as the unique Xanthorrhoea quadrangulata. However, in the world of plant collecting, ‘caudiciform’ has come to include plants with any significantly swollen part, broadening its definition and use.
This expanded definition of caudiciform is no longer strictly scientific, leading to various interpretations. For instance, plants like Boophane disticha may not traditionally fit the caudiciform criteria, yet they are often included in collections. Understanding and categorizing these plants can be challenging, especially when considering the vast diversity of plant forms.
Plant classifications, such as Phanerophytes, Chamaephytes, Hemicryptophytes, and Geophytes, categorize plants based on the location of their swollen parts in relation to the ground. This categorization is essential for collectors, particularly when artificial modifications, like raised caudexes, are common.
A central question in the caudiciform discussion is: What qualifies a plant as a caudiciform? Should it include plants with swollen leaves, branches, or roots? For instance, while Plectranthus ernstii has fat branches, and might not have a swollen stem, it’s often included in the caudiciform category. Conversely, succulents forming a single sphere, like Euphorbia obesa and Echinocactus grusonii, are typically excluded, despite their similarities to accepted caudiciforms like Pseudolithos cubiformis.
This brings us to another debate: should the swollen part of a caudiciform be above the ground, as seen in plants like Ariocarpus fissuratus? And what about plants with swollen roots or rhizomes, like Pereskia diaz-romeroana and Asparagus declinatus? These classifications are crucial for collectors who often expose these parts for display.
Interestingly, the concept of caudiciform plants extends to horticulture and gardening. Common crops like turnips and carrots could be considered caudiciforms due to their swollen roots. However, annual and biannual plants are usually excluded from this category, despite certain exceptions like Ipomoea batatas (sweet potato).
The evolution and growth patterns of caudiciform plants, like Bursera graveolens and Adansonia grandidieri, raise further questions. Some plants develop a significant caudex only to lose it later, while others take years to develop this feature. This growth aspect is crucial in determining whether a plant is considered a caudiciform at a particular stage of its life.
In conclusion, ‘caudiciform’ is a dynamic and open term in the plant world. While it’s challenging to define it precisely due to its broad usage and the diverse forms of plants, it remains a fascinating topic for plant collectors and enthusiasts. Whether you’re a seasoned collector or a curious gardener, understanding caudiciform plants adds an intriguing dimension to the world of botany and plant collection.
