Phedimus is a genus of succulent plants within the Crassulaceae family, often referred to as stonecrop. Originating primarily from Eastern Europe and Asia, these plants are recognized for their fleshy leaves and generally low-maintenance nature. The genus encompasses approximately 18 to 19 species, making them a popular choice in gardening due to their adaptability and distinctive appearance.
Common Phedimus Types and Their Characteristics
Phedimus plants have thick, fleshy succulent leaves and produce star-shaped flowers. Their growth habits vary, from mat-forming groundcovers to more upright forms. These characteristics contribute to their visual appeal.
One widely cultivated species is Phedimus spurius, also known as Caucasian stonecrop or two-row stonecrop. This species is a low-growing, spreading succulent with stems that often root as they sprawl along the ground. Its leaves are usually arranged in opposite pairs and can range in color from green to reddish, deepening to a burgundy hue in autumn.
Another common type is Phedimus kamtschaticus, sometimes called Orange Stonecrop or Russian Stonecrop. This species forms a mat of thick, fleshy, rich green leaves and produces bright yellow, star-shaped flowers that appear in clusters during the summer. A popular cultivar of this species is ‘Variegatum,’ which features creamy white edges on its green leaves.
Cultivating Phedimus
Phedimus plants thrive in ample sunlight, ideally receiving at least six hours of direct sunlight daily. While they can tolerate some partial shade, full sun promotes sturdier growth and more prolific blooming. In regions with intense heat, afternoon shade can prevent stress.
These succulents prefer well-draining soil, crucial for preventing root rot and fungal diseases. A sandy, gravelly, or loamy soil mix mimics their natural rocky and sandy habitats. Incorporating amendments like coarse sand or perlite can enhance drainage if the native soil is heavy clay.
Phedimus plants are highly drought-tolerant once established, storing water in their fleshy leaves. Overwatering should be avoided; use a “soak and dry” method, allowing the soil to dry out completely between waterings. Newly planted Phedimus should be watered regularly, about once a week, until well-established.
Maintenance for Phedimus is minimal. They do not require supplemental fertilization, as rich soil can lead to weak, leggy growth. Propagation is straightforward through stem or leaf cuttings, which can be rooted in well-draining soil after allowing the cut ends to callus for a few days.
Landscaping Applications of Phedimus
Phedimus plants are highly versatile and can be incorporated into various garden and landscape designs due to their hardiness and low-maintenance. They are well-suited for challenging areas where other plants might struggle.
Their mat-forming or creeping habits make them excellent choices for groundcover, effectively suppressing weeds and adding texture to garden beds. They are also widely used in rock gardens, where their drought tolerance and ability to thrive in shallow, well-drained soil make them a natural fit among stones and crevices.
Phedimus species are a common selection for green roofs, especially extensive systems, due to their shallow root systems and ability to withstand harsh rooftop conditions with minimal irrigation. These plants also perform well in container plantings, providing attractive foliage and blooms. They can serve as effective border edgings, creating defined lines and adding visual interest along pathways or garden perimeters.
