Russian Sage vs Lavender: A Comprehensive Comparison

Both Russian sage and lavender are popular herbs that have a long history of use in cooking and medicine. They are both members of the mint family, and they have a similar appearance.

From a distance, they both have beautiful blue-purple flowers and silver-green foliage. But do they come from the same species?

The answer is no. Russian sage (Perovskia atriplicifolia) is native to the mountains of central Asia, while lavender (Lavandula angustifolia) is native to the Mediterranean region.

Despite their different origins, they have both been naturalized in many parts of the world and are now grown as ornamental plants, other than their various uses in cooking and medicine.

They both come from a different Genus, with Russian sage being a member of the genus Perovskia, and lavender is a member of the genus Lavandula.

How to Differentiate Russian Sage from Lavender?

To the untrained eye, Russian sage and lavender may look fairly similar. Both plants have slender, grey-green leaves and delicate blue flowers. However, there are a few key differences that can help you correctly identify each plant.

Size

When trying to differentiate Russian sage from lavender, one of the easiest ways is by size. Lavender typically grows to be about two feet tall, with thin, delicate leaves. In contrast, Russian sage can grow up to four feet tall and has much broader leaves.

The difference in size is likely due to the different climates in which they grow – lavender originates in Mediterranean countries, where the climate is milder, while Russian sage is native to the steppes of Central Asia, where it has to adapt to harsh conditions such as high winds and intense sunlight.

Color

Another way to differentiate Russian sage from lavender is by color. Lavender plants are usually a deep purple color, while Russian sage tends to be more blue-ish.

This is due to the different compounds that are present in the two plants – lavender contains more linalool, which gives it a sweeter scent, while Russian sage contains more camphor, which gives it a more medicinal smell.

The different colors can also be helpful in terms of identification – if you’re looking for a plant to use in cooking, for example, lavender would be the better choice as it will impart a sweeter flavor.

Texture

Russian sage leaves are rough and slightly furry to the touch, while lavender leaves are smooth and silky. Russian sage’s leaves, when touched, can release a small amount of oil that can cause skin irritation in some people. When you touch lavender leaves, on the other hand, you should be able to feel a small amount of powdery residue.

This difference is due to the different compounds that are present in the two plants – Russian sage leaves contain more camphor, which gives them a slightly rougher texture, while lavender leaves contain more linalool, which makes them smoother.

Scent

Russian sage seems to lack that distinctive scent that we associate with lavender. If you’ve ever been lucky enough to catch a whiff of Russian sage, you’ll never forget it. The plant’s distinctively pungent aroma has been described as smelling like sage, lavender, and rosemary, all rolled into one.

Not surprisingly, this fragrance is one of the main ways to tell Russian sage apart from lavender. While both plants have incredibly fragrant flowers, lavender’s scent is more floral and sweet, while Russian sage has a more savory, herbaceous smell.

Lavender’s scent is often associated with shampoos, bath and shower gels, and soaps. Russian sage’s scent, on the other hand, is more often associated with mosquito repellents and mothballs.


Russian sage vs lavender: Final Thoughts

While lavender and Russian sage may seem identical at first glance, these two plants are different in terms of size, color, texture, and scent. Russian sage is a hardy plant that can tolerate drought and poor soil conditions, while lavender requires well-drained soil and regular watering.

Both plants produce beautiful flowers, but lavender blooms are more fragrant. In terms of height, Russian sage tends to be taller than lavender.

Finally, while both plants are popular choices for gardens, Russian sage is more adaptable to colder climates.
