What are Senecio Succulent Plants?
Senecio is a widespread genus of beautiful plants that belong to the Asteraceae or daisy family.
In the Senecio genus, more than 1000 species are grown around the world.
You will find highly prized perennial species to noxious weeds. Interestingly, you will find around 100 succulent species in this genus that can be grown as garden plants.
Remember that Senecio plants are regarded as toxic to pets. That’s why we suggest you either grow them in hanging baskets or keep your pets away from the plant.
Some of these plants are grown as trailing plants because of their climbing nature.
The leaves are fleshy and thick, and their colors range from green to bluish or even striped.
Side note: Though Senecio plants include many of the ‘string of’ type plants (e.g., string of pearls, string of bananas, or string of dolphins), the string of hearts is not part of the Senecio genus; the string of hearts plant is part of the Ceropegia genus.
For other ideas on what succulents to grow, take a look at our post on various types of succulents.
Senecio Anteuphorbium (Swizzle Sticks)
Senecio anteuphorbium is commonly known as Swizzle Sticks, is a deciduous shrub and remains dormant during the summer months.
This species stand upright and may reach up to 5 feet tall with green-gray-colored round stems.
The leaves have a lance-like shape. During the winter months, the plant produces beautiful white disk flowers.
These succulents are cold-hardy as they can tolerate temperatures as low as 40 degrees Fahrenheit.
This variety prefers growing in Mediterranean and Tropical climates. Remember that high humidity can be dangerous to these species.
We suggest you water these plants less often as they can retain water in their leaves. Moreover, excessive moisture can damage the roots.
Senecio anteuphorbium grows quite fast, and this succulent enjoys growing under partial or full sun.
Since they grow actively in winter, you should schedule your water period during this time.
Nevertheless, some gardeners suggest watering this succulent species moderately throughout the year. Like the other Senecio plants, these are very easy to propagate.
Senecio Articulatus
Senecio articulatus is generally known by other names – Hot dog cactus, Candle plant, or Sausage plant.
The stems have a unique cylindrical shape. This species is native to South Africa. This Senecio plant is perennial and may reach up to 2 feet tall.

Senecio articulatus doesn’t require too much attention to grow. They thrive even in the full sun or in partially shaded areas.
They are cold-hardy like most Senecio species, and they tolerate temperatures as low as 45 degrees Fahrenheit.
Remember that extended periods under freezing temperatures can inhibit growth. We suggest you keep this plant indoors during the winter months.
Since this species is extremely drought-tolerant, you don’t have to worry about watering too often. Water them only when the topsoil seems dry.
For feeding, you can fertilize them during the early spring. Use a cactus mix potting soil for growing these indoor plants.

Senecio canadicans is a relatively new variety of the Senecio genus with an attractive shape and unique color.
This catchy and unusual perennial has grey-white or silvery leaves with soft, velvety, or downy texture.
The foliage color and the yellowish flowers are the main reasons Angel wings are a popular variety of Senecio to grow.
Senecio canadicans can tolerate temperatures as low as 40-degree Fahrenheit.
Moreover, since these plants are native to the coast, they can tolerate saline soil. If you live in a dry region with well-draining garden soil, you can indeed plant this species in your garden.
While growing them in a container, ensure that you provide these plants with sufficient space because the leaves become huge.
They grow best under the full sun and cannot withstand heavy clay soil that retains moisture.
For propagation, you need to take the cuttings of young shoots in late summer. You may either plant the cuttings in water or soil.
Interestingly, the leaf decoction of Senecio canadicans can be used to treat gastric ulcers because of its gastroprotective activity [1].
It has been found that the aqueous extract can decrease lipid peroxidation.
Senecio Cineraria

Basic Senecio Plant Care Tips
In this section, we will briefly explain the basic requirements of Senecio plants. Their appearance and beauty will vary depending on how you fulfill their needs.
Light
Senecio succulent plants require bright, indirect light. If you live in a colder region, it is better to grow them in containers.
Once they are established, they can survive well in any region.
Remember that if you live in a hot climate, keeping them away from direct sunlight will be better.
Soil
You don’t have to worry about soil pH. Plants belonging to the Senecio genus enjoy a pH ranging between 6 and 7 (neutral range).
In addition, you should make sure that the soil is well-drained and avoid using heavy clay soil while preparing the mix.
Water and Fertilizer
Since Senecio is a heat-resistant genus, you need to water them only when the soil seems dry or the plant starts wilting.
Excessive water will damage the roots. Feed them with liquid fertilizer or organic manure during their growing period.
Temperature and Humidity
These plants can stand with brief periods of dampness or coldness, but prolonged exposure can be harmful.
They can withstand a low as 40-degree Fahrenheit temperature and don’t require high humidity.
Frequently Asked Questions
How big can Senecio plants grow?
Senecio plants can grow up three to four feet in height and three feet wide. Different varieties will have different sizes lengths. Typically, Senecio plants are maintained a bit shorter, with a standard height of one foot. These plants’ growth habits include wandering, clump-forming, and spreading. Its stems are covered with branches and roots, making it an ideal succulent ground cover.
Are Senecio succulents?
Yes, there are more than 1,100 different types of Senecio plants, with around 100 of them being succulents. These resilient, intriguing plants can trail, spread as groundcovers or grow into big shrubby-like plants, depending on their size and shape.
Can I grow Senecio in shady areas?
