The rise of cacti, succulent and succulent plants In interior and exterior decoration, it is no coincidence. This group of plants not only stands out for its great beauty and diversity of forms, but also for its adaptability and low maintenanceThey're perfect for those looking to bring life and freshness to any corner without having to spend too much time on maintenance, making them the centerpieces of gardens, terraces, and homes.
It's common to see combinations of a dozen cacti and small succulents in original arrangements, often accompanied by Zen figures, fountains, or decorative elements, creating harmonious spaces that invite relaxation and visual enjoyment.
Before diving into the world of these fascinating plants, it is essential understand the differences between cacti, succulents, and succulents, since these terms are often confused and, however, each one encompasses its own characteristics that define its appearance, care and decorative uses.
What are succulent plants?
The succulent plants They constitute a very broad botanical group that includes species capable of surviving in hostile, arid environments with low rainfall, thanks to unique adaptation mechanisms. The key to their success lies in their ability to store water in different organs (leaves, stems or roots), which allows them to withstand long periods of drought and intense heat.
Succulence is defined by two great abilities: reduce perspiration (to lose less water) and store water in specialized tissues. Thus, when rainfall or humidity is sufficient, the plant reserves water to use in difficult times. This evolution is accompanied by a very particular morphology: thickened leaves, fleshy stems, reduced surface area, and even protective hairs.
It is interesting to note that succulents are not restricted to a single botanical family, but are present in diverse families such as Crassulaceae, Cactaceae, Agavaceae, Aizoaceae, Euphorbiaceae, and Asphodelaceae, among others. This diversity explains the enormous variety of shapes, colors, and sizes they present.
Among succulents, we can find hanging epichambers, compact plants, multi-colored rosettes, and large specimens. In addition, many succulents have a highly prized ornamental value and are used in xerophytic gardening, minimalist landscaping, and bright interior decoration.
Succulent plants: definition and characteristics
The term crass It comes from the Latin "crassus", which means thick. It is used to identify those plants whose water storage is located mainly in the fleshy leaves, although sometimes also in short stems. Thus, succulent plants are considered a subgroup within the large group of succulents. That is, All succulents are succulents, but not all succulents are succulents..
Succulents have leaves and stems with thickened structures and often various geometric shapes such as rosettes, spirals, or columns. Their specialized tissue allows for efficient water retention, giving them great resistance to drought and remarkable self-sufficiency in pots and gardens with sporadic watering.
Some examples of famous and very popular succulent plants in gardening are:
- echeveria: recognized by their rosettes of leaves and their colors ranging from green to pink, blue or lilac.
- Aloe vera: appreciated for its medicinal properties and adaptability.
- Agave: protagonist of dry and minimalist gardens, with rigid leaves and sharp terminals.
- Crassula ovata (jade plant): highly valued as low-maintenance houseplants.
- Sedum: includes ground cover and hanging species, ideal for rock gardens or green walls.
Typical morphological characteristics of succulents are:
- Thick, fleshy leaves, generally thornless.
- Geometric formations such as rosettes to minimize direct sunlight exposure.
- Hair or wax on the surface to reflect solar radiation and prevent excessive perspiration.
- Extensive, superficial roots to quickly capture water from short rains.
Their compact size and slow growth make them perfect specimens for collecting and decorating small spaces, both indoors and outdoors.
Key differences between cacti, succulents, and succulents
Although there is a great deal of terminological confusion between these groups, it is essential to understand that they are not the sameThe main differences are detailed below:
- Succulent plants: These are the general group, including all those that store water in some part of their structure (leaves, stems, or roots). These include cacti and succulents, but also other botanical families of varying morphology.
- Succulents: a subgroup of succulents that stores water primarily in thick leaves. Examples: Echeveria, Aloe, Crassula, Sedum.
- Cactus: a highly specialized subgroup of succulents that belongs exclusively to the family CactaceaeThey store water in fleshy stems and have a unique characteristic: the areolas.
The biggest source of confusion comes precisely from cacti, as they are often thought of as a separate group of plants because of their spines, but they are actually highly evolved succulents. areolae They are small cushion-like structures or bumps located on stems, from which spines, flowers, and buds emerge. This characteristic is unique to cacti and therefore serves to differentiate them from other succulents.
Cacti often lack true leaves or have very small, modified leaves, with the stem being the main organ of photosynthesis. The spines serve protective functions and reduce water loss through evaporation, but they can also be used to capture dew or generate shade for the plant. There are cacti with and without spines, some even with whitish hairs or glochids, such as species of the genus Lophophora.
Similarities between cacti, succulents and succulents
Despite morphological and taxonomic differences, These groups share common adaptations which allows them to grow in extreme conditions:
- Efficient water storage: They have specialized tissues that retain and conserve moisture, allowing them to survive periods without watering.
- High resistance to drought: They are ideal for arid regions, equipped with mechanisms to withstand heat and lack of water.
- Low maintenance need: They require little care, occasional watering and protection from extreme frost.
- Long life in small spaces: They adapt to small pots and can stay healthy for years with few resources.
Specific characteristics of cacti
Los cactus They have a series of distinctive features that differentiate them from other succulents and crass plants. Their most identifying characteristic is the presence of areolas, small specialized buds from which spines (or glochidia), flowers, and branches emerge. This anatomical detail is unique to the family Cactaceae.
Cactus spines serve multiple functions:
- They reduce transpiration and water loss.
- They discourage herbivorous animals from feeding on the plant.
- They generate shade and protect the surface of the plant.
- In some cases, the whitish or hairy spines reflect solar radiation, helping to regulate temperature.
Furthermore, cacti typically bloom spectacularly and long-lasting, with large, showy flowers emerging directly from the areoles. Most cacti are native to the Americas, especially desert and semi-arid regions, although there are species adapted to tropical and temperate climates.
Specific characteristics of succulent plants
The succulent plants They stand out for their varied leaf shapes and arrangement. The best-known genera have rosette-shaped, spiral, or simple leaves, but always with a clear thickening for storing water. These plants may also have a thick cuticle, hairiness, or waxy coatings that increase their resilience.
Among the most popular botanical families we find:
- Crassulaceae: includes Echeveria, Crassula, Sedum and Kalanchoe.
- agavaceae: such as agave and yucca.
- Aizoaceae: with numerous genera of ornamental succulents.
- Asphodelaceae: where Aloe vera stands out.
Flowering in succulents is often discreet, although some species, such as Echeveria, can produce striking and highly decorative inflorescences.
Basic care for cacti, succulents and succulents
To enjoy healthy and spectacular cacti and succulents, it's a good idea to follow some essential recommendations tailored to the specific needs of each group:
Irrigation
- Due to its resistance to drought, it is ideal Water them only when the substrate is completely dry.
- Excess water is the main cause of death in cacti and succulents, as it promotes root rot.
- In winter, reduce watering frequency to a minimum, taking advantage of the dormant period of many species.
Light and location
- Cactus: They need direct sunlight, being the most tolerant to intense exposure.
- Succulents and other succulents: They prefer bright but indirect light to avoid burning their more delicate leaves. In very hot climates, protect them from direct sunlight during the middle of the day.
Substratum
- They need very draining substrates To prevent waterlogging, the most recommended method is a commercial cactus and succulent mix or a combination of soil, coarse sand, and perlite.
- In cacti, the sand content should be even higher to simulate natural desert conditions.
Temperature and humidity
- Most can withstand high temperatures and dry environments.
- Frost sensitive: Many species do not tolerate extreme cold, so in winter you should protect them if they are outdoors.
Fertilization
- Fertilize once or twice a year with a specific fertilizer for cacti and succulents during their growth period (spring-summer).
- Avoid fertilizing in winter or when the plant is dormant.
Reproduction and transplant
- They are easily propagated by leaf, stem, or sucker cuttings. Transplanting should be done when the plant has outgrown its pot.
- Wear gloves when handling cacti and avoid damaging the roots of more sensitive succulents.
Main decorative uses of cacti, succulents and succulents
The versatility and beauty of this group of plants makes them essential elements for:
- Xerophytic and low-water gardens, ideal for arid areas and warm climates.
- Interior design, thanks to their compact size and the ease with which they can be combined in pots of different shapes and colors.
- Living walls and vertical gardens, as they require shallow substrates and adapt to unconventional supports.
- Centerpieces, terrariums, and custom arrangements for any setting.
Curiosities and frequently asked questions
