In the world of landscaping succulent gardens occupy a special position. The general term “succulents” represents a large group of plants and species families that are not even related to each other. Succulent plants are the true children of the desert. Distinguished by a variety of forms and colors, the plants from this group have perfectly adapted to surviving in the harsh conditions of the desert. Nowadays, almost all representatives of succulents can be found on the windowsills of city apartments. These plants add natural beauty and vitality to any space with their “juicy” leaves and stems.
Succulents form an extensive and diverse group of plants that do not require special care and look great both singly and in compositions. In this article, you will not only get to know them better, but also learn how they can serve as a beautiful and unpretentious element of your landscape.
What is a succulent? As we mentioned, this plant group includes a huge variety of species and when you want to grow them in your garden, there is a good chance that you may not be sure what exactly to look for. Succulents are often characterized as plants with fleshy, juicy or thick leaves, stems and even roots, in which water is easily stored. Many succulents come from dry regions, such as deserts and semi-deserts. The most famous plants of the desert are cacti which are also classified as succulents. Maybe you have heard the saying – “All cacti are succulents but not all succulents are cacti”.
The impressive appearance and stunning adaptability have made succulent plants one of the favorites of landscape designers. Nowadays, they are experiencing a peak of popularity and are actively used in a variety of designs – you can see them in alpine hills, rockeries, along garden paths, in drought tolerant gardens and in original compositions from succulents in pots, terrariums and various planters.
Succulent gardens – combining beautiful colors in landscape designs
When we talk about Nature as a landscape designer, then we mean that it takes decades for its creations and they can only be destroyed by natural disasters or incompetent human intervention. Man has long ago appreciated the decorative value of succulents as a material for landscape design. Practically, in every botanical garden in the world one can find rockeries, where different kinds of succulents are planted in a picturesque combination.
Following their aesthetic taste and design abilities, many amateur gardeners who collect succulents are involved in creating such compositions. If Nature spontaneously, without thinking about the results, sometimes creates her own masterpieces of landscape, then a person must always follow certain rules to achieve the goal and mimic Nature in the best possible and visually pleasing way.
The selection of plants depends on the level of light. For sun-exposed locations, apart from the decorative properties, one needs to consider the ability of species to withstand direct sunlight, the lack of protection from precipitation, strong winds or nighttime frost. Practically, all succulents need well draining soils and experts advise to add sand and gravel to the native soil when the soil in your garden is not draining well. Beginners need to realize that despite the fact that some species prefer regular moisture and others will survive weeks without water, standing water is not beneficial to succulents. So, what is the right place to plant your succulents? When we talk about landscape designs, your succulent garden shoud be located on a place which receives a good amount of sunlight, moderate watering and sandy soil.
When planting succulents, you need to leave some space between them for free expansion. Fill in the empty places with pebbles, driftwood, etc.
Group the species with similar needs for lighting and watering in different flower beds. Remember that these plants do not need fertile soil.
One of the most naturally looking landscape designs with succulents are the rockeries which are especially suitable for slopes or terraced areas. In addition, the plants are a great choice for retaining walls as they will visibly revive the design of the terraces and help the hill area become a focal point in the landscape.
What are the advantages of succulent gardens? What do you need to know when buying succulents? How to choose the right species for your garden? Having in mind that the group includes thousands of species, the decorative possibilities of these plants are practically unlimited. The main advanatges are:
Colorful appearance – succulents come in so many colors that you may have difficulties to choose just a few;
Texture – this is one huge advantage, as each variety comes with its own unique texture and add exceptional charm to your indoor or outdoor garden appearance;
- Low maintenance – your succulents can survive weeks without water;
- Easy reproduction and transplantation;
- You can use them to create a variety of compositions – rockeries, living walls, miniature-gardens, terrariums, wall panels, table centerpieces, etc.
How to choose succulents for your garden and care for them? Succulent gardens can be designed in many different ways but one of the main rules is to use plants with similar requirements for lighting and watering. When choosing species for your landscape design you need to remember some of the main characteristics of succulents and depending on your idea, garden plot, personal taste and preferences, a visit to a local nursery will be a pleasant trip.
- Succulents vary in size which means they will require different care and will also vary in price. Bigger species (or plant in a large container) usually require less care.
- Always choose healthy plants. For example, the leaves of overwatered plants fall off easily if you bump them slightly. Healthy plants have firm leaves and bright colors.
- Very often you will find more than one plant in a pot, which is normal. Not all succulents come as a single plant.
- Replant all the species that you bought as soon as possible.
Despite the fact that succulents are unpretentious and can be grown even by a child, there are certain rules that you need to know and follow to make sure your plants are healthy.
Moderate temperate is an important factor. Succulents do not love big differences in daytime and night time temperature – they will feel comfortable when the difference is not more than 4-5 degrees. Keep in mind that many species go into hibernation during winter peiof – from about October to March – and the optimal temperature for this perios is between 5 °C and 12 °C.
Most succulents prefer bright light, but there are species that need a partial shade, so make sure you know the needs of your species and group them in the right way.
Irrigation needs to be in accordance with the particular conditions and soil type. It is well known that succulents, left unattended indoors for a week or two, perfectly survive the lack of moisture, because by nature they are ready for this. The general rule for succulent gardens is to water the plants when they are dry during summer months and reduce watering to once a month during winter.
Planting and reproduction – Propagation of succulents can be done with stem cuttings and leaves. The separated stalk can not be put in water, it is necessary to allow it to dry for two days, and then plant immediately into the soil. The leaves are simply placed on wet ground without any cover. The best time for breeding is from April to August.
Succulent gardens – amazingly beautiful landscape designs
A variety of species often serve as a kind of “living colors” for landscape designers who create amazing decorative compositions.
Succulents are one of the most popular plants for vertical gardening as well. You can start with a small panel, and then, having mastered the technology, build a real living wall or a green wall in the garden or on the balcony, even indoors.

The visual appeal of the combination bwteen succulents and stones is amazingly harmonious and refined.
