Introduction
The Stonecrop family, also known as the Crassulaceae family, is a diverse group of flowering plants that include alpines and succulents. This botanical treasure trove has around 160 genera with more than 3500 species. Some popular members of this family include sempervivums (also known as houseleeks), sedum (stonecrops or jellybeans), and many others that showcase unique characteristics, adaptations, and habits.
Alpine Stonecrops
One striking aspect of the Crassulaceae family is the alpine stonecrops. These plants are adapted to grow in high-elevation mountainous regions with harsh climates where water can be scarce. They thrive in the cold, rocky environments found in these areas and often exhibit characteristics that help them survive such extreme conditions.
One example of an alpine stonecrop is Sedum telephium, commonly known as Autumn Joy. This plant boasts rosettes of fleshy, bright green leaves, which give way to large pink flowers during its bloom period in late summer and early fall. The blooms have a lasting beauty, turning from pink to red as they age, making the Autumn Joy an excellent addition to gardens looking for colorful interest in autumn.
Another species of alpine stonecrop is Sedum nussbaumerianum, also known as Green Carpet Stonecrop. This low-growing plant has a dense mat of dark green leaves that form a beautiful ground cover. It can adapt to various light conditions and is often used in gardens as an attractive yet low maintenance filler for beds or borders.
Succulent Stonecrops
The Crassulaceae family also contains many succulent species, which are known for their ability to store water efficiently. This adaptation has allowed them to thrive in environments with limited water resources such as dry deserts and rocky landscapes. Succulents can be found in a variety of sizes and shapes, from the small, leaf-like Sempervivum arboreum (Tree Houseleek) to the large, branching Sedum spectabile (Showy Stonecrop).
Sempervivums are known for their rosettes of fleshy leaves that form a bowl shape. They can be found in various colors, from green and silver to purple and red, making them visually appealing for gardeners who appreciate diverse foliage options. Sempervivum tectorum (Hens and Chicks) is one particular species with rosettes of bright green leaves that form a bowl shape. This plant forms small offsets, which give it its common name “hens and chicks.” It has a low-growing, spreading habit, making it suitable for use in rock gardens or as ground cover.
Sedum spectabile is a large, branching succulent with a unique star-like shape to its flowers. This plant blooms in late summer and autumn with vibrant pink or purple blossoms that attract pollinators. The Showy Stonecrop’s foliage also provides winter interest due to its color variations during the colder months.
Cultivating and Growing Crassulaceae
Stonecrops are generally easy to grow, making them popular with both amateur and experienced gardeners. They are adaptable and thrive in a variety of soil types, from sandy and well-drained to clayey and loamy, as long as they have good drainage. The majority of Crassulaceae species prefer full sun conditions for optimal growth; however, some alpine stonecrops can tolerate more shade or partial sun exposure.
When it comes to watering, most stonecrop plants require minimal attention and are well suited to drought-resistant landscapes. Overwatering should be avoided, as it can lead to root rot in these moisture-loving yet water-conserving plants. Fertilization is also not typically necessary for Crassulaceae plants as they have adapted to thrive in nutrient-poor environments.
Conclusion
The Crassulaceae family is a diverse group of flowering plants that showcases an incredible array of species, from alpine stonecrops to succulent beauties. Their unique adaptations and characteristics make them invaluable additions to gardens and landscapes where water can be scarce or light conditions challenging. With proper care and attention, these fascinating plants will thrive and provide both visual appeal and practical benefits for years to come.
