Habitat:

The Pachypodium lamerei f. cristata naturally occurs in the dry, arid regions of southern Madagascar. This habitat is characterized by its hot, sunny climate and infrequent rainfall, conditions that have shaped this plant’s unique adaptations for survival in a challenging environment.

Description:

Pachypodium lamerei f. cristata, commonly known as the crested Madagascar Palm, is a unique and striking succulent. Unlike its standard counterpart, the crested form exhibits a fascinating growth pattern. The main stem, which in the regular form grows upright, in the cristata variety mutates and broadens into a fan-like or wave-like shape, creating a sculptural and unusual appearance. This crested growth is due to a rare phenomenon called fasciation, where the cells at the growth point mutate and cause the stem to flatten and spread out rather than growing round and upright. Typically, the crested Madagascar Palm can reach a height of about 30-60 cm, making it a manageable size for container gardening. The stem is thick and swollen, serving as a water reservoir to withstand drought conditions. It’s covered in sharp spines, which add to its distinctive look. The leaves are long, slender, and green, forming mainly at the top of the stem, giving it a palm-like appearance. However, it’s important to note that despite its common name, this plant is not a true palm.

Cultivation:

Cultivating Pachypodium lamerei f. cristata requires an understanding of its natural arid habitat. This succulent thrives in bright, direct sunlight, so it’s essential to provide it with plenty of light, ideally a south-facing window when grown indoors. The plant is well-suited for warm climates and should be kept in temperatures above 12 degrees Celsius to prevent damage from cold. When it comes to soil, well-draining cactus mix is ideal, as it prevents root rot by quickly draining excess water. Overwatering is a common issue, so it’s crucial to let the soil dry out completely between waterings. During the winter months, when the plant is dormant, reduce watering significantly. Fertilizing is not a frequent requirement; a diluted cactus fertilizer can be used during the growing season for added nutrients. Repotting should be done every few years or when the plant outgrows its container. Handle with care due to its sharp spines.

Propagation:

Propagating Pachypodium lamerei f. cristata is usually done through seeds or occasionally through cuttings. Seed propagation is more common, as cuttings of crested forms can be challenging. When growing from seeds, sow them in a well-draining soil mix and keep them warm and lightly moist until germination, which usually takes a few weeks. Patience is key, as the crested form can take several years to develop its unique shape.

Curiosity:

The crested form of Pachypodium lamerei is a result of a genetic mutation known as fasciation. This mutation creates the plant’s distinctive, flattened growth pattern. Each crested plant is unique in its shape, making it a sought-after specimen for collectors and enthusiasts of unusual succulents.
