Senecio Crassissimus
Senecio Crassissimus, sometimes called “Vertical Leaf Senecio,” is an original succulent admired for its architectural habit and unusual color. Its thick, flattened, almost oval leaves are arranged vertically, as if standing upright like blades around the stem. This distinctive arrangement gives the plant a highly graphic and decorative look, perfect for lovers of modern compositions.
The leaves of Senecio Crassissimus range from blue-grey green to violet along the edges, creating a subtle and elegant contrast. The waxy epidermis protects them from heat and drought while enhancing their greyish tone. This color play becomes even more pronounced when the plant receives abundant light.
Over time, Senecio Crassissimus forms a compact small shrub reaching 60 to 90 cm in height. Its semi-woody stems bear rosettes of vertical leaves that overlap harmoniously, creating a structured and balanced appearance. Its silhouette, both simple and elegant, makes it ideal for bright corners or dry gardens.
Its thick, vertical foliage is a direct adaptation to its environment: this particular orientation limits direct sun exposure, reducing evaporation and preserving internal moisture.
🌞 Direct sun: 5 to 6 hours per day enhance its purple hues and compact growth.
🌤️ Filtered sun: During very hot summer periods, light protection at midday prevents burns.
⚠️ Lack of light: Too much shade leads to elongated stems and loss of color.
🌱 Spring / summer: Water every 12 to 15 days, always waiting until the substrate is completely dry.
🍂 Autumn / winter: Reduce drastically; sometimes light watering every 3 to 4 weeks is sufficient.
⚡ Tip: Use a draining mix with added perlite or pozzolana to prevent any risk of rot.
🌞 Ideal: Between 18 °C and 28 °C.
❄️ Minimum: Can tolerate 5 °C briefly, but should be protected once temperatures drop below 10 °C.
🏠 Wintering: Bring indoors in a bright location in cold areas.
🪨 Recommended substrate: Use cactus substrate or succulent potting soil.
💡 Tip: Improve drainage by adding 40% perlite or pozzolana.
🌸 Season: Summer.
🎨 Color: Small bright yellow flowers in clusters.
🕑 Duration: A few days to a week, depending on growing conditions.
💡 Tip: A liquid cactus fertilizer in spring can encourage flowering.
