What are succulent plants?

Succulent plants —also called succulents— are those that have developed thickened and fleshy organs (usually leaves, but sometimes stems or even roots) specialized in storing water. This adaptation allows them to survive and thrive in arid environments with poor soil and scarce rainfall, where other plants would struggle to thrive.

The term "succulent" comes from Latin succulents, which means "juicy," reflecting the characteristic texture of their tissues. Succulents often come in striking colors and shapes, from bright green to lilac, reddish, or bluish tones, and can be found both in miniature size and as large shrubs. Some species, such as Lithops (living stones), are tiny and go unnoticed among the stones, while others such as the Aloe vera They have long, robust leaves with serrated edges.

In addition to storing water, many succulents have additional adaptations such as:

• Hairs or trichomes that retain dew and ambient humidity on the leaf surface.
• Compact forms or low growth to reduce transpiration and water loss.
• Waxy cuticles and sunken stomata to minimize evaporation.
• Ability to perform CAM photosynthesis, opening the stomata mainly at night to reduce water loss.

What are the main families of succulent plants?

Succulent plants are distributed across numerous botanical families. Some of the most important and representative, along with their key characteristics, are:

• agavaceae: About 300 species, mainly with succulent leaves. The most notable are Agave y Yucca.
• Aizoaceae: More than 2.000 species of succulent leaves, including miniature jewels such as Lithops y Pleiospylos.
• apocynaceae: About 500 species, including succulent stems (e.g., adenium).
• Asphodelaceae: Approximately 500 species with fleshy leaves, where the following are found: Aloe y haworthia.
• Crassulaceae: Around 1.300 species with storage organs in the leaves. This includes genera such as Crassula, echeveria, Kalanchoe y Sempervivum.
• didieraceae: Only 11 species, with succulent stems.
• Euphorbiaceae: More than 1.000 species, many of them with succulent stems and leaves.
• Portulacaceae: 26 genera with succulent organs on both stems and leaves.

It is important to note that the term "succulent" is not strictly defined from a botanical point of view, and can include a multitude of species with similar water retention strategies, even if they differ significantly in their geographical origin or morphology.

Outstanding features of succulent plants

• Thick leaves and stems: They store water in specialized cells.
• Wide variety of shapes and colors: From compact rosettes to bushy structures, spiral, triangular shapes, etc.
• Adaptation to water stress: They can survive without watering for extended periods, making them ideal for dry environments and people with little time for watering.
• Resistance and longevityMany species live for decades and can withstand adverse conditions.
• Decorative versatility: They allow for creative combinations in flowerpots, vertical gardens, centerpieces, terrariums, and minimalist compositions.

How do succulent plants multiply?

One of the enormous advantages of succulent plants is their ease of multiplication, which allows you to have new plants from a single mother. The most common methods include:

• Leaf cuttingsRemove a healthy leaf and let it dry for two or three days until it forms a callus. Then place it on dry substrate and wait for roots and new leaves to sprout.
• Stem cuttings: Cut a segment of stem, let it heal for a few days and plant it in loose soil until it roots.
• Division of suckers or shootsMany succulents generate secondary shoots around them, which can be separated and planted separately.
• Sowing seeds: A slower and more laborious method, but it allows you to obtain new varieties and experiment from scratch.

Succulent propagation is usually best during spring and summer, when the plants are actively growing. It's essential to use clean tools, allow the cut areas to dry before planting (to avoid fungal infections), and use well-drained substrates.

Types of succulent plants: essential and original varieties

The world of succulents encompasses thousands of species, but some genera and types are especially popular for their beauty, rarity, or ease of cultivation. Below is a detailed guide to the main varieties:

Aeonium

A genus of about 70 species, most of them endemic to the Canary Islands and Madeira. They form rosettes of fleshy green, brownish, or even purple leaves, depending on the variety. They can develop long stems, and their rosettes often branch out into showy clumps. Their size varies from 30 centimeters to over a meter in some species.

Aloe

Composed of more than 500 species, the most notable is the Aloe vera, famous for its medicinal properties. The Aloe They have thick, triangular, spirally arranged leaves with serrated edges. They grow in a rosette shape and, in warm climates, may flower with large, tubular, yellow or orange spikes.

argyroderma

A small South African genus known as "living stones." It grows to just 2-3 centimeters tall and has opposite, fleshy, rounded leaves. Highly prized for collecting and miniature gardens.

conophytum

With over 400 species, these miniature plants are ideal for small spaces. They have two leaves fused into a rounded structure and produce small yellow or violet flowers.

Crassula

One of the most popular and varied genera, with more than 600 species and numerous forms: from shrubs such as Crassula ovata (jade tree), to triangular-leaved varieties (Crassula pyramidalis). They withstand indoor and outdoor conditions well.

Lithops (Living Stones)

Small succulents camouflaged among the stones, with just two fused leaves and colors that mimic the mineral environment. When they bloom, they produce daisy-like flowers. Ideal for collectors.

Pachyphytum

A Mexican genus of plants with very fleshy, rounded, powdery leaves. They grow no taller than 20 centimeters, and their small flowers range in color from green to pink.

Pleiospylos

Between 20 and 40 miniature African species. Opposite, globose, and very thick leaves, with spectacular central yellow or purple flowers.

Sempervivum

A genus distributed throughout Europe and Asia, famous for its great resistance to cold. They form dense clusters of rosettes covered with hairs and runners, with pink or reddish flowers.

Other succulents of interest

• KalanchoeKnown for its colorful and prolonged flowering, it requires indirect light and moderate watering.
• Senecio rowleyanus (Rosary): Ideal for hanging, with pearl-shaped leaves.
• Sedum: Widely used as a ground cover or in rock gardens.
• Afra portula: Easy-care hanging succulent, known as the “mini jade tree.”
• Ceropegia woodii: : Chain of hearts, elegant and perfect for indoors in hanging pots.
• rhipsalis: Hanging branches, perfect for creating green cascading effects in baskets.

Essential care for succulent plants

The greatest attraction of succulents lies in their easy maintenance. However, to keep them looking healthy and beautiful all year round, it's key to know certain growing guidelines:

Light and location

• Abundant (but filtered) sunlightMost succulents require at least 4-6 hours of light daily. Direct sun promotes intense colors, but some sensitive species (Haworthia, Gasteria, certain Echeveria) prefer partial shade or bright indirect light.
• Avoid intense sun in summer: Especially during the central hours, to prevent burns.
• Well-ventilated spaces: They provide a dry environment and prevent fungal diseases.
• For indoor plants, place your succulents near south-, east-, or west-facing windows, and rotate the pots occasionally to ensure even growth.

Adequate watering

• Succulents prefer deep and spaced waterings: Let the substrate dry completely between waterings. In general, water every 7-10 days during warm weather and every 20-30 days during winter.
• Avoid waterloggingExcess water is the main enemy, as it rots roots and encourages fungi.
• Do not wet the leaves or leave standing water in dishes.: Directs water to the substrate and removes excess after watering.
• If you have any doubts, insert a toothpick into the soil: if it comes out clean, it's time to water.

Substrate and drainage

• Very draining substrate: It's essential. You can use commercial substrates for cacti and succulents, mixtures of universal soil and coarse sand/perlite, or pumice with 20-30% compost.
• Pots with drainage holes: They allow excess water to flow and prevent root asphyxiation.

Subscriber

• Fertilize in spring and summer, when the plants are growing.
• Use specific fertilizer for succulents, liquid or granulated, with low nitrogen content so that the tissues do not soften.
• Avoid fertilizing in fall and winter, when plants go dormant.

Transplant

• Repot every 2-3 years or if the plant is outgrowing the pot. Always do this in spring.
• Do not water immediately after transplanting.: Wait 4-5 days to reduce the risk of rot.

Temperature and rusticity

• Most tolerate cool temperatures, but only some (such as Sempervivum, jovibarba o Sedum) can withstand light, occasional frosts below -2 °C. Those of tropical origin should be kept indoors in winter.
• Avoid exposing them to hail or sudden changes in temperature.

Propagation: Keys to multiplying your succulent plants

• Division of suckersIdeal for species that produce secondary rosettes (Echeveria, Sempervivum, Aloe, etc.). Separate the offspring once they have their own roots.
• Leaf or stem cuttings: Leave a leaf or piece of stem exposed for 1-3 days, then plant it in dry substrate and wait for it to take root.
• Propagation by seeds: Suitable for repopulating pots, although it requires patience and stable humidity and temperature conditions.

Common problems, diseases and pests

Succulents are very hardy, but can be affected by:

• Excess irrigation: Causes root and leaf rot. Symptoms: soft leaves, black spots, unpleasant odor.
• Ethiolation: The stems lengthen and turn white due to lack of light.
• Sunburn: Brown spots from sudden exposure to intense sun.
• PestsMealybugs, mites, aphids, caterpillars, snails, and slugs. Remove manually or use specific treatments.
• fungi and bacteria: They appear due to humid conditions and poor ventilation. Apply fungicides if necessary.

Tip: Keep your plants clean, check the undersides of their leaves regularly, and make sure the soil is always dry before watering again. Use terracotta pots, which promote evaporation and prevent excess moisture.

Flowering succulents: species and tips to stimulate flowering

Not all succulents flower readily in cultivation, but some species are known for their floral displays. Prominent examples include:

• Agave: It blooms only once at the end of its life, producing a spectacular central inflorescence.
• Sempervivum: Generates flower stems with flowers in shades of pink and red.
• Kalanchoe: : Long flowering indoors if it receives enough light.
• echeveria: Colorful inflorescences in spring and summer.
• Crassula ovata: Small star-shaped flowers, usually white.

To encourage flowering, respect dormant periods, reduce watering in winter, and fertilize during the growing season.

Hanging succulents: decorative styles and recommended species

• Senecio rowleyanus (Rosario): Spherical leaves that hang forming long green curtains.
• Sedum morganianum (Donkey's tail): Long stems with fleshy, compact leaves, with a hanging appearance and very decorative.
• Ceropegia woodii (String of Hearts): Heart-shaped leaves, ideal for indoor spaces and hanging pots.
• rhipsalis: Hanging branches, perfect for creating green cascading effects in baskets.
• Afra portula: Imitation jade hanging tree, easy to care for and excellent for beginners.

Ideas for decorating with succulent plants

Succulents stand out for their decorative versatility, adapting to both indoor and outdoor environments. Here are some practical suggestions:

Terrariums and miniature gardens

Terrarium growing allows you to create miniature landscapes inside glass containers, recycled fish tanks, cups, or jars. It's important to control watering and drainage, using a base of gravel and loose substrate to prevent waterlogging. Add decorative stones, figurines, and moss for an original finish.

Rockeries and succulent gardens

Rock gardens, both in the ground and in large planters, allow you to combine different succulents with stones, logs, and gravel. Low-maintenance succulent gardens require little watering and provide a modern, natural look to the space.

Vertical gardens

Green succulent walls (vertical gardens) are a trend. They can be created with special frames or modular panels, using small, shallow-rooted species (Echeveria, Sedum, Sempervivum, Pleiospilos, etc.). They bring freshness and life to walls, balconies, or bright interiors.

Original pots and combinations

Use pots made of porous materials such as clay or terracotta and combine shapes and colors to create attractive arrangements. Remember to choose compatible species in size and watering/lighting requirements.

Themed centerpieces

Ideal for celebrations, events, or simply to decorate tables and furniture. You can create themed centerpieces for each season (Halloween, Christmas, spring) by combining succulents with other dried and natural decorative elements.

Frequently asked questions about succulent plants

• How often should I water my succulents? Only when the substrate is completely dry. In summer, once a week or every ten days. In winter, every 2-4 weeks.
• How to prevent succulents from stretching and deforming? Provide sufficient natural or artificial light. "Etiolation" is caused by a lack of light.
• Is it necessary to fertilize succulents? Yes, during spring and summer, but use low doses of specific fertilizer for succulents.
• What to do in case of rot? Remove affected parts and replant in clean, dry substrate.
• Can I place them in the bathroom or kitchen? Avoid humid or poorly ventilated environments to prevent fungi.
• When should I transplant my succulents? Do this in the spring every two or three years, or when the roots are sticking out of the container.

• Periodic rotation: Rotate the pots to ensure symmetrical development.
• Cleaning: Remove dust from leaves with a soft brush to prevent stomatal obstruction and improve photosynthesis.
• Selection of species according to climate: If you live in a cold area, opt for Sempervivum, Sedum o jovibarba. For warm climates, echeveria, Kalanchoe y Aloe They are ideal.
• Suitable pots: Prefer terracotta ones and make sure they have good drainage.
• Avoid sudden changes in environment: If you move your indoor plants outdoors, gradually acclimatize them to the sun.

With all this information, succulents become an excellent choice for both novices and discerning collectors. Thanks to their incredible resilience, the variety of species, and the ease with which they are propagated, they allow for unleashing creativity in any setting. From sustainable gardens to original centerpieces, succulents prove every day that beauty and functionality can go hand in hand in the plant world.
