The maximum size of sedum can vary depending on the specific variety and growing conditions. Generally, sedums are considered relatively small to medium-sized plants, although there are some larger cultivars available. Let’s explore the different types of sedums and their potential size.
Creeping or groundcover sedums, such as Sedum acre and Sedum spurium, typically have a low, spreading habit. These varieties form dense mats of foliage and are well-suited for filling in gaps in the garden or cascading over walls. They generally reach a maximum height of around 6 inches (15 cm) and can spread up to 12 inches (30 cm) or more. These sedums are excellent for rock gardens or areas with poor soil quality.
Mid-sized sedums, like Sedum ‘Autumn Joy’ and Sedum ‘Matrona’, are popular choices for many gardeners. These varieties usually grow to a height of 1 to 2 feet (30 to 60 cm) and have a clumping or upright habit. They produce clusters of colorful flowers that attract pollinators and add visual interest to the garden. Mid-sized sedums are versatile plants that can be used as fillers in mixed borders or as focal points in container gardens.
Taller sedums, such as Sedum ‘Herbstfreude’ (also known as Sedum ‘Autumn Joy’), can reach heights of 2 to 3 feet (60 to 90 cm) or even more. These varieties often have sturdy stems that support their large flower heads. Taller sedums are well-suited for the back of borders or as stand-alone specimens in the garden. They provide vertical interest and can create a stunning display when in bloom.
It’s worth noting that the size of sedums can also be influenced by growing conditions, including the amount of sunlight, soil fertility, and moisture levels. In optimal conditions, sedums tend to grow larger and spread more vigorously. However, they are generally adaptable and can tolerate a range of conditions, including drought and poor soil.
While sedums are not typically considered large plants, there are variations in size among different cultivars. Whether you’re looking for a low groundcover or a taller statement plant, there is likely a sedum variety that will suit your needs and preferences. Experimenting with different types and observing their growth in your garden can be an exciting and rewarding experience.
