Senecio Haworthii can be a conversation piece in any garden arrangement. The leaves are its eye-catching feature. Approximately 2cm long, the leaves of this succulent shrub are covered by dense, shiny, silver-white colored hairs that make them resemble cocoons.

Thus, the succulent is also known as Cocoon Plant. Another popular alias is Wooly Senecio. The leaves of Cocoon Plant are arranged by its stems and this gives it a thick, columnar appearance.

How to Grow and Care for Senecio Haworthii

The cylindrical, cocoon-like leaves of Senecio Haworthii make it a favorite of many horticulturists. Placed against the backdrop of green-colored succulents, the silver-white, fuzzy hairs of Cocoon Plant make it stand out as an accent piece.

The leaves are not just for show. Their thickness and density are a result of the leaves adapting to changes in temperature that range from -6ºC to 40ºC (42.8ºF to 104ºF).

With a bit of planning, Senecio Haworthii is easy to grow and care for.


As a garden succulent, plant Senecio Haworthii in an area that receives 6 hours of morning sunlight every day.

This type of succulent grows best at a temperature between -4° C – 10° C (-25° F – 50° F). If the temperature in your region drops below -1° C (30° F), it would be best to move Cocoon Plant indoors.

As an indoor succulent, place Senecio Haworthii near a window that receives 3 to 6 hours of morning sunlight.


Senecio Haworthii is a drought-tolerant succulent and can survive long periods of time without water.

The best method to use for watering is the soak and dry method. Check the topsoil. If it feels dry to the touch, it’s ready for watering.

If you want to be sure, insert a stick an inch into the soil. Remove the stick and if the end feels dry, then go ahead and water until the soil is completely soaked.

Cut back on the watering schedule during the winter months because the soil tends to stay moist longer.

Pot and Soil

The best pot to grow Senecio Haworthii is ceramic or made of terracotta because it allows moisture to escape from the soil.

If the roots are immersed in moist soil for a long period of time, they will rot and develop fungi that can infect the entire plant. It’s also important to make sure the pot has a drain hole with a mesh cover to allow excess water to spill out.

Cocoon Plant is resilient and can thrive in different types of soil but we recommend sandy loam potting mix with gravel added to improve drainage.

Method 2 – Leaf Cuttings Method

Step 1: Choose a leaf from the stem that has no signs of disease.

Step 2: Perform a clean cut of the leaf from the stem by using a sterilized and sharpened knife or a pair of garden shears. To ensure a successful propagation, make sure no parts of the leaf are on the stem.

Step 3: Place the leaf cuttings in a warm and dry place and allow it to develop hard calluses in 2 to 3 days.
