Senecio: varieties, characteristics, and how to grow these fascinating succulents
Senecio is one of the most appreciated succulent plant genera among plant enthusiasts. This genus includes hundreds of different species, many of which have become popular for their diverse and unique shapes, trailing growth habit, and ease of cultivation.
Some Senecio species have become true icons in the world of decorative plants: just think of the famous String of Pearls or the curious String of Dolphins.
Characteristics of the Senecio plant
Plants belonging to the genus Senecio are part of the Asteraceae family and are widespread in many parts of the world. Succulent varieties are known for their ability to store water in their leaves, making them resilient and easy to manage, with infrequent watering requirements.
The main characteristics of Senecio are:
- Fleshy and decorative leaves
- Trailing or upright growth
- High drought resistance
- Minimal maintenance
Thanks to these qualities, Senecio is a perfect plant even for those with little experience with succulents.
Senecio: a versatile genus
Senecio is a very unique genus because it comprises many different forms. Such a vast variety of appearances that they don't seem to belong to the same genus!
Among the many existing species, some varieties have become particularly popular for their unique aesthetics. Here are some of the most fascinating ones.
Senecio Rowleyanus (String of Pearls)
Senecio Rowleyanus, also known as String of Pearls, is probably the most famous variety of this genus: an evergreen.
Its spherical leaves resemble small green pearls strung along long trailing stems, creating a spectacular decorative effect.
This plant is perfect for:
- Hanging pots
- Shelves
- Bright bookshelves
With good light and moderate watering, Senecio Rowleyanus can grow rapidly, forming long green cascades.
Senecio Herreianus
Senecio Herreianus is very similar to Rowleyanus but features teardrop-shaped leaves, meaning they are more elongated and oval.
Among its main characteristics:
- Elegant trailing growth
- Characteristic teardrop shape
- Very decorative appearance
Senecio Rowleyanus Variegated
Senecio Rowleyanus Variegated is a rare and highly prized version of the classic String of Pearls.
Its leaves retain the spherical shape typical of Rowleyanus, but feature white or cream variegation, which makes the plant even more decorative.
Senecio Stapeliiformis
Senecio Stapeliiformis is a completely different variety compared to trailing Senecio: one that deviates from small succulent leaves to take on a different and unique appearance.
This plant features cylindrical, upright stems, decorated with green and purplish stripes reminiscent of Stapelia (hence, the reference to the genus!).
Senecio Peregrinus (String of Dolphins)
Senecio Peregrinus, also known as String of Dolphins, is one of the most curious succulent plants.
Its leaves are incredibly similar in shape to small dolphins jumping out of the water, from which its name is derived.
This plant is much loved because:
- It has uniquely shaped leaves
- It grows with a trailing habit
- It is perfect for hanging pots
Senecio Peregrinus is a true collector's plant, highly appreciated by enthusiasts.
How to cultivate Senecio
Light: where to place Senecio?
Senecio loves very bright environments: an essential characteristic for it to grow well, preventing rot and wilting. It can also be exposed to direct sunlight for a few hours, but it is best to avoid the intense sun typical of the hottest hours.
A well-lit window is the ideal position.
Watering: when to water Senecio?
Being a succulent plant, Senecio requires infrequent watering.
It is important to:
- Allow the substrate to dry out completely between waterings
- Avoid water stagnation
- Reduce watering during winter, when the light is less intense and the hours of daylight are shorter.
Substrate: how to prevent root rot
Choosing the right substrate is extremely important to prevent Senecio from rotting, given its low and specific watering frequency: Senecio leaves are succulent and fleshy, which means they store water.
Our Cactaceae & Succulent mix is an extremely light, well-draining, and sandy substrate.
