6 Differences Between Russian Sage vs Lavender

Today, we’re comparing two popular plants: Russian sage and lavender. Both share similarities, but they’re distinct in their ways.

⚡QUICK ANSWER⚡: Russian sage (Salvia yangii) is taller (3–5 ft), blooms from July to October, and handles cold and humidity better. Lavender (Lavandula spp.) is shorter (1–3 ft), blooms earlier (May–August), and is prized for scent and culinary uses but dislikes humidity. Both are drought-tolerant and attract pollinators.

Russian sage, botanically known as Salvia yangii, is a subshrub species. It belongs to the Salvia genus, although this wasn’t always recognized. It was formerly named Perovskia atriplicifolia and considered its own genus.

Salvia yangii is predominantly found in Asia, especially in regions like China and Pakistan. It’s less commonly seen in Eastern Europe. This plant thrives in rocky, mountainous terrains with well-drained soil and full sun exposure.

Conversely, lavender, scientifically named Lavandula, is a genus with several species. Most often, when people mention lavender, they are referring to one of the three main species:

• Lavandula angustifolia (English lavender)
• Lavandula stoechas (Spanish lavender)
• Lavandula dentata (French lavender)

While there are many other lavender species, for this comparison, I’ll focus on these three.

Lavender’s natural habitat is in the Mediterranean regions of southern Europe. Similar to Russian sage, it’s a sun-loving plant that thrives in well-drained soil.

Flowering🌸

One of the most striking contrasts between Lavender and Russian sage lies in their blossoms. From their color to their form and timing, these plants exhibit distinct variations.

Flower Size and Structure

Russian sage features inflorescences that rise from its primary stem, branching out into slender flower stalks, which average around 4 inches (10 cm) in length. Attached to these stalks are numerous small flowers, each about an inch in size. This arrangement results in panicles that span approximately 13 inches (32 cm), densely populated with these minute blossoms.

Lavender, in comparison, presents a different picture. While it, too, has a stem bearing flowers, it lacks the lateral stalks seen in Russian sage. Consequently, its flowers cluster closely together. These flowers are smaller than Russian sage’s, about half an inch in diameter. Lavender’s floral arrangement is reminiscent of rye spikelets, but instead of grains, we see small blooms.

Flower Coloration

Russian sage predominantly flaunts blue blossoms with a subtle hint of purple, though some variants lean towards either a lighter or darker shade of blue.

Lavender, conversely, boasts a broader color palette. Most strains within the Lavandula genus exhibit a signature blue shade, so distinctive it’s often referred to as “lavender” color.

But that’s not all. Breeders worldwide have introduced numerous hybrids and varieties. Lavender offers a plethora of colors, including blue, purple, violet, pink, white, and even pale yellow – certainly a wider spectrum than Russian sage. In this color contest, Lavender shines brighter.

Blooming Seasons

In terms of flowering periods, Russian sage, when properly tended, graces gardens from mid-summer up to late September or early October. However, in colder climates, this period may be abbreviated.

Lavender, in contrast, tends to blossom earlier. The French lavender variety, for instance, starts flowering from late spring to July, and in warmer USDA zone 8 areas, this can stretch to summer’s end. English lavender starts its display in June, continuing throughout the summer till October.

Lavender is smaller📏

Lavender tends to be more compact and has a denser growth habit than Russian sage. Typically, a mature lavender plant won’t grow beyond 3 feet in height. To give a specific example, English lavender is one of the more petite varieties and usually caps out at around 30 inches tall.

In terms of width, lavender plants often grow wider than they are tall. With a few years of growth, some lavender bushes can spread beyond 3 feet in width.

On the other hand, Russian sage can readily tower to heights of over 5 feet and can span about 4 feet wide. Essentially, this makes Russian sage nearly twice as tall as lavender. Additionally, the sage has a broad, conical shape, while lavender plants often resemble a flattened sphere.

Foliage Distinctions🍃

Russian sage sports leaves that can grow up to 2 inches (5 cm) in length and 1 inch (2.5 cm) in width. These leaves are connected to the stem by petite petioles and display a finely-divided pattern, giving them a unique texture.

French lavender leaves are particularly striking. They exhibit a lovely pattern along their edges and possess a vibrant green coloration. English lavender contrasts with its gray leaves, which are both shorter and narrower compared to their French counterparts.

In terms of aroma, lavender leaves pack a punch. They’re plumper than those of Russian sage and release a powerful scent when crushed. While Russian sage leaves do offer their own fragrance, they don’t quite match the intensity of lavender’s.

Lavender likes alkaline soil🧪

Lavender thrives best in alkaline soil conditions. However, it can also adapt to neutral or mildly acidic soils.

English lavender is somewhat tolerant, comfortably growing in soils with a pH level between 6.5 to 6.7. In contrast, French lavender leans more towards neutral to alkaline soils, even favoring pH levels up to 8.

Russian sage is less particular about soil pH. It does well in neutral to alkaline soils but is content with a pH range of 6.5 to 6.8.

Hardiness❄️

Russian sage is notably hardy, thriving in USDA zones 4 through 9. Typically, it doesn’t require any special winter care or protection.

Lavender, however, presents a bit more variability in its hardiness. Take French lavender as an example: if you’re situated in an area colder than USDA zone 7, you might run into some challenges.

English lavender flourishes within USDA hardiness zones 5 to 8. It’s well-suited to cold snaps and even snowy conditions.

Usage🧴

Russian sage is utilized in aromatherapy. Its fragrance aids in relaxation and achieving a sense of calm. Beyond that, its applications are fairly limited.

In contrast, lavender is incredibly versatile. For starters, its scent forms the foundation of countless cosmetic products, ranging from perfumes to lotions and shampoos. Moreover, many cleaning products feature the calming aroma of lavender.

💊Medicinally, lavender oil and other parts of the plant are frequently used to alleviate stress and enhance sleep quality. It’s a common component in both modern and traditional medicine.

🍽️From a culinary standpoint, lavender is a star. It’s a key ingredient in a myriad of dishes, particularly in Mediterranean desserts and so much more.

Maintenance🛠️

☀️Both Russian sage and lavender thrive in direct sunlight but can manage with some partial shade. However, lavender has a slightly higher need for sunlight compared to Russian sage.

💧When it comes to watering, Russian sage is more forgiving and can handle somewhat moister soil for extended periods. In contrast, lavender requires well-draining soil and should be watered less frequently.

🌱Russian sage is the bigger plant and has a preference for somewhat richer soil. Meanwhile, lavender is quite content in poorer, sandy soils. Nonetheless, it’s advisable to fertilize both plants annually to ensure optimal growth.

✂️Pruning requirements differ between the two. Russian sage is best pruned in the fall, focusing on the removal of dead branches. Lavender, on the other hand, should be pruned post-flowering.

🐛In terms of diseases and pests, both plants face similar threats. Various diseases and pests can affect them, with treatments typically involving fungicides and insecticides.
