Sedum sexangulare, Also known as yellow sedum, Cat's claw o stonecrop, is one of the most prized ground cover succulents for its adaptability, resilience, and the ever-changing beauty of its foliage and blooms. This perennial, a member of the Crassulaceae family, excels in xeriscaping, green roofs, rock gardens, and flowerbeds, thanks to its low maintenance and ability to thrive in harsh conditions.
What is Sedum sexangulare like?
El Sedum sexangulare is a perennial succulent plant herbaceous in appearance and creeping in habit. Reaches a height of between 5 and 15 centimeters Usually, rarely exceeding 20-30 cm in exceptional conditions, although its horizontal development can extend widely, covering rocky surfaces or slopes.
Its fleshy leaves They grow opposite each other in six spiral rows along the stems, forming dense, compact clumps. These leaves are glossy, deep green for most of the year, but They change to copper, reddish or orange tones in autumn and winter, especially when they receive abundant sunlight. This tonal variation is part of their ornamental appeal.
During spring and summer, It produces dense and abundant terminal inflorescences, composed of numerous yellow star-shaped flowers., each with five petals. These flowers create a golden blanket effect on the foliage and attract numerous pollinators such as bees and butterflies, increasing biodiversity in the garden.
Its stems, in addition to being creeping and branched, can send out roots at points of contact with the ground, which explains its rapid ability to form carpets and cover large spaces.
Distribution, habitat and landscape uses
From Central and Eastern Europe, its natural habitat includes rock crevices, walls, slopes and arid coastal areas, where drought conditions and poor soils are common. Thanks to this adaptability, it has become naturalized in other regions and is widely used in Mediterranean and low-irrigation gardening.
Due to its resistance to drought, low temperatures and its small size, Sedum sexangulare is ideal for:
- rockery gardens: covers and beautifies stony surfaces with a natural effect.
- Extensive and landscaped green roofs: provides insulation and promotes water retention, improving the energy efficiency of buildings.
- Vertical gardens and facades: Adds texture and color to living wall and vertical element projects.
- Borders and paths: defines paths and delimits spaces thanks to its soft, leafy texture.
- Xeriscape: a fundamental component in low water consumption gardens.
- Erosion control: Its roots help stabilize slopes and sloping soils.
- Pots and planters: Excellent option for balconies, terraces and patios with little irrigation.
Botanical characteristics and variety within the Sedum genus
The genus Sedum groups more than 400 species of succulents., with an astonishing diversity of sizes, shapes, foliage and flowering colors. Among the most popular in gardening are the Sedum acre (with yellow flower and creeping habit), Sedum album (dark green leaves and white flowers), sedum spectabile (pink flowers and upright bearing), sedum spurium (ground covers with reddish foliage and fuchsia flowers), and sedum morganianum (hanging stems and rounded leaves).
In all varieties, Succulent leaves play a key role in resisting drought, storing water within. Some acquire intense colors in response to cold or direct sunlight, and flowering can vary significantly in color and season depending on the species.
Sedum sexangulare Care: Complete Guide
If you want to enjoy the spectacular and robustness of your Sedum sexangulare for years to come, follow these essential care instructions:
Location, light and temperature
Unlike other succulents, Sedum sexangulare tolerates both full sun and semi-shade..

supports high summer temperatures and moderate frosts (down to -17°C in well-established varieties). The leaves may turn reddish in winter due to the cold, without serious damage. If grown indoors in very cold climates, it can be moved to bright, protected areas during the harshest months.
Substrate and soil conditions
To avoid rot and disease problems, The substrate must be very loose, sandy or stony, and have excellent drainage.An ideal mix includes a universal substrate mixed with perlite, pumice, gravel, or coarse sand (at least 40-50% drainage components). This ensures that water doesn't accumulate in the roots, preventing fungus and root suffocation. Knowing the differences between cacti and succulents can help you better choose the right substrate. differences between cacti, succulents and crass plants.
Sedum sexangulare is not very demanding in terms of pH, although it appreciates slightly acidic or neutral soils and can thrive in both calcareous and siliceous soils, even in very thin or stony substrates.
Irrigation
The key to watering succulents is to avoid excess water.Sedum sexangulare requires spaced watering, allowing the substrate to dry completely between waterings. In spring and summer, weekly or biweekly watering may be sufficient, increasing the frequency only during periods of extreme heat or direct sun exposure.
In cold or wet months, it is recommended to reduce watering to a minimum, even skipping it during rainy and frosty periods. It tolerates short periods of prolonged drought thanks to the water reserves it stores in its leaves.
Subscriber
Sedum sexangulare does not require constant fertilization, although it may benefit from Light fertilizers with specific fertilizer for cacti or succulents Once a month during spring and summer, especially if it has been in the same pot for years. For more details, see Caring for Sedum and other flowering succulentsExcessive fertilization can lead to soft growth that is more susceptible to disease, so low, slow-release doses are recommended.
Pruning and maintenance
Once established, maintenance is very low. A light pruning after flowering To maintain a compact appearance, remove dead stems. If the clumps age or lose vigor, it's recommended to divide them to rejuvenate them and encourage denser growth. It's a good idea to periodically remove weeds and withered leaves to prevent pests and improve the ornamental appearance.
Common pests and diseases
Sedum sexangulare is very resistant to pests and diseases, but not immune. The most common problems are root rot due to excessive watering and, occasionally, the presence of pests such as aphids, mealybugs, or nematodes in very humid environments or overly compacted soils. You can expand on succulent plants and their care.
To avoid these problems:
- Ensures perfect drainage in the substrate and prevents waterlogging.
- Check the plants regularly and clean affected leaves or stems.
- For pests, use organic treatments such as potassium soap or neem oil, and enhance biological control with beneficial insects like ladybugs.
- Disinfect pruning tools to avoid transmitting pathogens.
Multiplication and propagation
El Sedum sexangulare multiplies with enormous ease through:
- Stem cuttingsSimply cut a healthy section, let it dry for a few hours, and place it on moist substrate. It roots quickly and is the most common method.
- Per sheet: Separate a healthy leaf, place it on soil, and after a few days roots and new shoots will appear.
- Mata Division: Ideal for rejuvenating aging plants. The entire plant is removed and divided into several sections, which are then relocated to new locations.
- By seed: less common in gardens, the process is longer and reserved for obtaining large quantities or hybrids.
Due to its vigor and rooting capacity, it can be considered invasive in some contexts, so its spread should be controlled if grown near sensitive species.
- Sedum acre: Very hardy, low-growing, carpet-forming, and with intense yellow flowers in late spring. It tolerates very severe frosts.
- Sedum album: Green or reddish leaves, white flowers, and high drought resistance. Ideal for rockeries and slopes.
- sedum spurium: reddish or green foliage and fuchsia or purple flowers; fast-growing and excellent for covering large areas.
- sedum spectabile: upright growth, deep pink flowers in summer and autumn, great ornamental value and excellent for flower beds and arrangements.
- sedum morganianum: the famous “Donkey’s Tail”, perfect as a hanging plant indoors and on terraces.
- sedum reflexum: needle-shaped leaves, blue-green in color and yellow flowers; widely used in rock gardens.
Ecological and decorative benefits
In addition to its ornamental value, Sedum sexangulare contributes to improving the environment through:
- Improves air quality thanks to photosynthesis and oxygen production.
- Reduces stormwater runoff by retaining moisture on roofs or slopes.
- Increase biodiversity by attracting pollinating insects and strengthening the food web.
- It requires few resources water and fertilization, contributing to sustainable gardening.
