Overview of Sedum Types or Varieties
Sedums can be classified into several categories based on their growth habits and characteristics. The main types include:- Creeping Sedum
- Tall Sedum
- Trailing Sedum
Creeping Sedum
Creeping sedums are low-growing varieties that spread horizontally, making them excellent ground cover options. They typically have fleshy leaves that can come in various colors, including green, yellow, red, and variegated forms.-
Examples:
- Sedum acre: Also known as goldmoss stonecrop, this variety features bright yellow flowers and is often used in rock gardens.
- Sedum album: Known as white stonecrop, it has small white flowers and is favored for its drought resistance.
- Sedum reflexum: Commonly referred to as reflexed stonecrop, it produces clusters of yellow flowers in the summer and is ideal for borders and rocky areas.
Tall Sedum
Tall sedums grow upright and can reach heights of 1 to 2 feet. They often produce larger flower heads that attract pollinators like bees and butterflies.-
Examples:
- Sedum 'Autumn Joy': This popular variety blooms with pink flowers in late summer that mature to a deep red in fall.
- Sedum spectabile: Known for its large pink flower clusters, this variety is a favorite for adding height to garden beds.
- Sedum 'Purple Emperor': This variety features dark purple foliage that contrasts beautifully with its pink flowers.
Trailing Sedum
Trailing sedums are characterized by their long stems that cascade over the edges of pots or walls. These varieties are often used in hanging baskets or as container plants.-
Examples:
- Sedum morganianum (Burro's Tail): This popular houseplant has long trailing stems covered in plump leaves.
- Sedum sarmentosum (Stringy Stonecrop): Known for its thin stems and small round leaves, this sedum is perfect for ground cover or hanging arrangements.
- Sedum 'Kelp Forest': A unique variety that features trailing stems with a rich green color.
Growing Conditions for Sedums
Light Requirements
Most sedums thrive in full sun, requiring at least six hours of direct sunlight daily. While some varieties can tolerate partial shade, they may not bloom as profusely or maintain their compact growth habit.Soil Preferences
Sedums prefer well-draining soil. They thrive in sandy or gravelly soils that allow excess water to drain away quickly. Heavy clay soils can lead to root rot, so it's essential to amend the soil with sand or perlite if necessary.Watering Needs
One of the key advantages of sedums is their drought tolerance due to their water-storing leaves. Newly planted sedums should be watered regularly until established. Once established, they typically require little supplemental watering unless experiencing prolonged dry spells.Temperature and Hardiness
Sedums are adaptable to a wide range of temperatures but generally prefer moderate conditions. Most varieties are hardy in USDA zones 3-10. However, extreme heat above 90°F can cause leaf scorch, so providing some afternoon shade during heatwaves can be beneficial.Care Tips for Sedums
- Fertilization: Sedums do not require much fertilization; in fact, overly rich soil can lead to weak growth. If needed, a light application of compost in spring can promote growth.
- Pruning: After flowering, trim back spent blooms to maintain the plant's shape and encourage bushier growth. This also helps prevent flopping in taller varieties.
- Pest Management: Sedums are generally pest-resistant but may occasionally attract aphids or mealybugs. Regular inspections and treatments with insecticidal soap can help manage infestations.
- Propagation: Sedums are easy to propagate through leaf cuttings or offsets. Simply remove a healthy leaf or offset from the parent plant and allow it to callous over before planting it in well-draining soil.
