Senecio serpens is a tantalizing succulent plant. It has bluish-green leaves that appear to be dusted with chalk and are reaching up to the sky. The elongated, upward-moving direction of its leaves and its powdery/chalk-like edges have given Senecio serpens the nickname “Blue Chalksticks”.
When Senecio serpens is given enough sunlight, the edges of its leaves turn purple.
Blue Chalksticks can grow up to 36-inches or 91cm. It comes from the Asteraceae family and is native to South Africa. The succulent blooms small, white flowers in the summertime.
How to Grow and Care for Senecio Serpens
Senecio serpens is easy to grow and maintain. It is popularly used as a garden cover although you can also grow Blue Chalksticks for container gardens.
If used to adorn a container garden or as ground cover, Senecio serpens should be planted in an area the receives 6 to 8 hours of morning sunlight every day.
As an indoor plant, Senecio serpens should be placed near a window that receives the most sunlight per day. You can also place the succulent under a Grow Light for up to 16 hours every day to get the right amount of lighting the plant needs.
Senecio serpens is a succulent plant that is highly tolerant to drought. During the growing season, Blue Chalksticks will hardly need water. Giving the plant more water than it requires will cause its roots to rot.
The recommended schedule is once every three to four weeks. Before watering, make sure the soil is completely dried out. You can do this by feel or by inserting a stick into the soil. If the stick comes out dry, water the plant.
Water the soil until it drips from the drainage holes and accumulates on the tray. Once the tray is filled up, throw away the water. Do not let the plant rest on excess water and avoid watering the leaves.
3. Pot and Soil
Place Senecio serpens in a pot that is big enough to allow its roots to grow. Choose a pot that is made of ceramic material and free of glazing. A ceramic pot encourages evaporation and allows the soil to dry out completely. Make sure the pot has a drainage hole.
The best type of soil for Blue Chalksticks is one that is well-aerated and well-draining. You can opt for cactus soil or specially-formulated succulent potting soil then add perlite or coarse sand at a 1:1 ratio to further improve drainage.
It is recommended to give Blue Chalksticks fertilizer at least once a year. The fertilizer should be diluted to half-strength by adding water and it must be low in nitrogen. The fertilizer will not be necessary if Senecio serpens is planted outdoors.
