The Rose of Jericho is known for its remarkable “resurrection” ability. When dry, it appears as a tightly curled, brown ball. Upon rehydration, it slowly unfurls its branches, transforming into a vibrant, green specimen. This unique adaptation allows it to endure harsh desert conditions, primarily originating from arid regions.
Does the Rose of Jericho Have a Scent?
The question of whether the Rose of Jericho possesses a discernible scent is frequently asked. The “false” Rose of Jericho, Selaginella lepidophylla, typically has a very subtle aroma, often described as earthy or musky. This faint scent is usually only noticeable when the plant is rehydrated, to the point where many individuals may not perceive any fragrance at all. Some users have noted a subtle pine-like scent.
In contrast, the “true” Rose of Jericho, Anastatica hierochuntica, generally lacks any significant or distinct scent. It is not known for emitting a strong, pleasant, or floral aroma. The plant itself is not cultivated for its fragrance, and its extract is typically noted as having no discernible odor in scientific contexts.
Distinguishing the Two Rose of Jericho Varieties
Understanding the “Rose of Jericho” often requires distinguishing between two entirely different plants that share this common name: Selaginella lepidophylla and Anastatica hierochuntica. Selaginella lepidophylla, often called the “false” Rose of Jericho or resurrection moss, is a spikemoss native to the Chihuahuan Desert in the United States and Mexico. When dry, it forms a tight, brown ball, and upon contact with water, it unfurls its fern-like, green foliage as it rehydrates. This plant is able to revive even if uprooted, entering a dormant state rather than dying.
Anastatica hierochuntica, known as the “true” Rose of Jericho, is an annual herb belonging to the mustard family and originates from the desert regions of the Middle East, particularly around Jericho. When it dries, its branches curl inward, forming a ball, and it disperses its seeds like a tumbleweed. Unlike Selaginella lepidophylla, Anastatica hierochuntica can only genuinely “resurrect” and turn green if it remains rooted in the ground; an uprooted specimen will not revive. Visually, Anastatica hierochuntica has a more branch-like structure compared to the fern-like appearance of Selaginella lepidophylla when revived.
Factors Affecting Scent Experience
Several variables can influence whether a subtle scent from a Rose of Jericho, particularly Selaginella lepidophylla, is detectable. The plant’s hydration state plays a role, as any faint earthy or musky odor is more likely to be perceived when rehydrated. When completely dry, the plant is dormant, and scent molecules are not actively released. Environmental conditions, such as air circulation and humidity, can also impact how widely and intensely a scent is dispersed. A well-ventilated area might dissipate any subtle scent more quickly, making it less noticeable.
Individual differences in olfactory sensitivity also greatly affect scent perception. What one person perceives as a faint earthy smell, another might not detect at all. Factors like age, gender, and overall health status can influence an individual’s ability to identify and detect odors.
Common Misconceptions About Rose of Jericho Scent
Common misunderstandings exist regarding the Rose of Jericho’s scent, often leading to expectations of a strong or pleasant fragrance. Neither Selaginella lepidophylla nor Anastatica hierochuntica is recognized for a robust, sweet, or floral scent. The idea of a “rose-like” aroma is a significant misconception, as the plant’s common name refers to its appearance when unfurled, not its smell.
Any claims of a strong, pleasant odor often stem from commercial products, such as perfumes or oils, that use the “Rose of Jericho” name but incorporate synthetic fragrances. These products do not reflect the natural scent profile of the plant itself, which remains largely odorless or possesses only a very faint, natural aroma.
