Senecio haworthii (Wooly senecio) Care Guide

Last Updated on March 21, 2021 by Sophie

The Senecio haworthii is known by many names; Ashweed, Cocoon Plant, and Wooly senecio on account of its fluffy white leaves. A succulent dwarf shrub, if you’re looking for a unique plant to add an unusual texture to your indoor garden, then the Senecio haworthii is the plant to purchase. Here’s a complete care guide, as well as propagation tips and how to water this plant!

Senecio haworthii

A part of the Senecio genus, the plant originates in South Africa and typically grows at elevations of around 900 to 1200 metres. Originally called ‘Cacalia tomentosa,’ the plant never reaches a huge height and its compacted leaves feel akin to felt or fabric. Interestingly enough, the term ‘Senecio’ comes from the Latin word for ‘Old Man’ and refers to the furry nature of the succulent plant.

Instead, a mature Senecio haworthii typically reaches 10 – 25 centimetres at maturity. In the summer, provided that the plant is given the right growing conditions, it will produce bright yellow flowers. Please note that this plant is toxic to pets and humans.

Senecio haworthii Plant Care & Watering Guide

Watering your Woolly senecio Plant

Like many succulents, the Ashweed plant is a drought tolerant plant, meaning that it can go long periods of time between waterings (and thus making it the perfect plant for those who find it hard to keep on top of a watering schedule.) With this being said, one of the most common causes of succulent death is overwatering, and so under-watering is most definitely preferable to overwatering. For a more in depth guide, here’s how to water succulent plants.

Best soil conditions for the Ashweed Plant

Due to the succulent nature of the plant, the whale fin enjoys being in well-draining soil with plenty of grit and sand. Ideally, this silver-leafed plant should be planted in a cactus mix as opposed to a soil which contains too much organic matter. A specific succulent mix can often be purchased at your local garden centre, particularly those who specialise in indoor plants.

Best light conditions for the Senecio haworthii

Like most succulents, the Senecio haworthii will do best in bright sunlight, such as by a window, though they can also get by in slightly shadier conditions (of course, with lower light the plant will also need to be watered less frequently and will likely grow at a slower rate).

How to Propagate Senecio haworthii

There are two easy methods when it comes to propagating the wooly senecio. The first of these is to propagate via leaves. Simply gently twist off a leaf from the stem of the plant and leave it to dry out for a couple of days. Then place the leaf on soil and mist every few days.

Within a couple of weeks, roots should start to appear. Trial this method with multiple leaves at a time in order to maximise your chances of success. The other propagation method for the cocoon plant is incredibly similar. Simply use a sterile pair of cutters to cut a portion of stem from the plant. Then leave it to dry out for a couple of days before placing the piece on soil.
