Mullein and Great Mullein are two different species within the same plant genus, Verbascum. While they share some similarities, there are distinct differences between the two.
One of the key differences lies in the appearance of their flowering spikes. Great Mullein, also known as Verbascum thapsus, has dense spikes of yellow flowers that can reach impressive heights, sometimes exceeding six feet. These spikes are densely packed with flowers, creating a vibrant display. On the other hand, Orange Mullein, scientifically called Verbascum phoeniceum, has flowering spikes that are more interrupted and less dense. The flowers are usually in shades of orange, pink, or purple, and they are arranged in a looser pattern along the spike.
Another noticeable contrast is found in the leaves of the two species. Great Mullein leaves are densely covered in fine hairs, giving them a soft and fuzzy texture. The upper surface of the leaves appears grayish due to this dense hairiness. In contrast, Orange Mullein leaves are less hairy and have a more greenish color on the upper surface. While some hairiness may be present, it is not as prominent as in Great Mullein.
The shape and arrangement of the leaves also differ between the two species. Great Mullein has large, ovate leaves with prominent lobes and a decurrent leaf base. This means that the upper leaves partially wrap around the stem, creating a wing-like appearance. Orange Mullein, on the other hand, has narrower leaves with less pronounced lobes. Its upper leaves are only slightly decurrent against the stem, not as prominently as in Great Mullein.
In terms of cultivation, both Mullein and Great Mullein are hardy plants that can tolerate a wide range of soil conditions. They are often used in gardens and landscaping for their striking appearance and ability to attract pollinators. However, due to their different growth habits and flower characteristics, they may be used in different ways within a landscape design.
To summarize the differences between Mullein and Great Mullein:
Flowering Spikes:
– Great Mullein: Dense spikes of yellow flowers, can reach impressive heights.
– Orange Mullein: Interrupted and less dense spikes of orange, pink, or purple flowers.
Leaf Characteristics:
– Great Mullein: Densely hairy leaves, grayish upper surface, large ovate shape with prominent lobes and decurrent leaf base.
– Orange Mullein: Less hairy leaves, greener upper surface, narrower shape with less pronounced lobes and slightly decurrent upper leaves.
These differences in appearance make each species unique and offer various options for gardeners and landscapers to choose from, depending on their desired aesthetic and design preferences.
