The world of succulent varieties is vast and diverse, with each species exhibiting unique characteristics. However, within the same botanical genus, there are often species that closely resemble each other. This similarity can sometimes lead to confusion and potential deception by sellers. Jelly Bean and Sedum corynephyllum are such succulents that are challenging to differentiate. Do you know the key factors to distinguish between these two? Let's explore them together!
Jelly Bean Succulent and Sedum corynephyllum
Sedum pachyphyllum Rose, also known as Jelly Bean, is a lovely succulent belonging to the Crassulaceae family. It's named after its plump, jelly bean-shaped leaves. This succulent typically grows to a height of 4 to 6 inches and can spread up to 12 inches. It prefers bright and filtered sunlight but can still tolerate direct sunlight, especially in cooler climates. Soak and Dry is the best method for the succulent, and remember to water less frequently during the dormant winter months. A cactus or succulent mix with a well-draining gitty is ideal for its health. You can propagate Sedum pachyphyllum through stem or leaf cuttings. How to Propagate Jelly Bean from Stem Cuttings.
Sedum corynephyllum, commonly known as Corynephyllum Stonecrop, is a succulent plant that also belongs to the Crassulaceae family. Full sun is the preferred condition for these succulents, and they can be propagated either through stem cuttings or by division. Sandy or rocky soils work well in the growth of Sedum corynephyllum. Like most succulents, Sedum corynephyllum prefers to dry out between waterings. Water conservatively, ensuring the soil has thoroughly dried before the next watering. It is known for its hardiness and ability to tolerate a wide range of conditions. It is often grown as a ground cover or in rock gardens.
How to Differentiate Jelly Bean and Sedum corynephyllum
Leaf Shape Differentiation
When it comes to comparing the leaf shapes of Sedum pachyphyllum Rose and Sedum corynephyllum, there are distinct differences that can be readily observed. In the case of Sedum pachyphyllum Rose, commonly known as Jelly Bean Sedum, its leaves present a larger upper portion and a narrower lower section, showcasing a curvaceous form reminiscent of a banana. Conversely, Sedum corynephyllum exhibits leaves with a smaller upper region and a wider lower area, and these leaves tend to be slightly straighter, bearing a resemblance to cucumbers in shape.
Conversely, Sedum corynephyllum boasts relatively shorter leaves, while Jelly Bean Sedum displays comparatively longer ones. When these two varieties are placed side by side, these distinctions in leaf shape become even more pronounced and easily discernible.
Leaf Color Differentiation
Under normal circumstances, the leaves of Jelly Bean exhibit a bluish-green hue with a touch of verdancy. However, their leaf tips turn red or pink in environments characterized by ample sunlight, cooler temperatures, or certain temperature differentials. On the other hand, Sedum corynephyllum presents a lush green color as its baseline, with the yellowish leaf tips transitioning to shades of orange or orangish-yellow under the same environmental conditions. It's worth noting that Sedum corynephyllum displays relatively minor variations in leaf color changes. It's also worth mentioning that the similar-looking succulent known as Sedum rubrotinctum 'Aurora' will turn entirely red under abundant sunlight exposure.
Furthermore, the leaves of Sedum pachyphyllum Rose are coated with a thin layer of waxy white powdery frost, while the leaves of Sedum corynephyllum are smooth and lack any powdery coating. This characteristic can also be used to distinguish between Jelly Bean and Sedum rubrotinctum.
Distinguishing between Jelly Bean Sedum and Sedum corynephyllum also relies significantly on the differences in their stem characteristics. The stem of Jelly Bean Sedum is tender, green and exhibits a somewhat sinuous nature. No matter how it grows, Jelly Bean always possesses the succulent-trait stem. This means that after the leaves drop, the stem's epidermis prominently displays leaf scars, making it a notable feature for identification.
In contrast, Sedum corynephyllum showcases conspicuously woody stems. The appearance of its stem closely resembles tree bark, featuring well-defined, aged, and yellowish grain patterns. These stems grow in a straight and smooth fashion, leaving no visible traces after the leaves have fallen. How to Care for Woody Stem Succulents.
Sedum Jelly Bean exhibits a proclivity for producing an abundance of side shoots, resulting in the formation of clusters plants. Over time, these clusters can expand to fill entire containers, creating a lush display. Notably, when these side shoots first emerge, they are characterized by a powdery white appearance, adding a distinctive feature to the plant.
However, Sedum corynephyllum follows a more solitary growth pattern. Its stems remain upright and singular without readily forming clusters of offspring plants. Any emerging side shoots from Sedum corynephyllum typically exhibit a green coloration right from the outset, in stark contrast to the white-tinged shoots of Jelly Bean Sedum.
Aerial Root Differentiation
The extent to which they develop aerial roots and the reasons behind their aerial root growth differ between them. Jelly Bean Sedum is recognized for its tendency to develop aerial roots, driven by various factors. Soil compaction, which hinders root respiration, prompts aerial root growth to access oxygen. Nutritional demands from budding side shoots stimulate these roots to seek added nutrients and moisture. Root rot issues can also drive aerial root development as a survival response to damaged or unhealthy root segments.
Sedum corynephyllum doesn't have the same affinity for growing aerial roots as Jelly Bean does. When they do emerge, it often signifies potting stress, driving the plant to absorb air moisture to compensate for soil deficiencies, especially in arid conditions or high humidity. Sometimes, these roots may signal underlying root issues, potentially causing stem desiccation and shrinkage.
Although these two varieties may initially appear as identical twins, upon closer examination, we can discern differences in their stems, leaves, and propagations. The purpose of this differentiation is to help you better understand these two varieties so that you can select higher-quality plants based on these characteristics when making a purchase. In the process of distinguishing them, we are, in fact, uncovering their unique beauty from different angles. Hope you love both of them!
