In this guide, we’ll explore the Lamiaceae family in a way that’s accessible, scientifically accurate, and infused with practical insight. You’ll learn how to identify Lamiaceae plants, what makes their anatomy so distinctive, how they evolved, and why they matter so much to gardeners, cooks, herbalists, pollinators, and global agriculture.
Whether you’re growing herbs on a windowsill or walking through a Mediterranean hillside, you’ll come away with a clearer appreciation for the incredible mint family.
Lamiaceae Family Overview
The Lamiaceae family—often called the mint family—includes more than 7,000 species across roughly 240+ genera, making it one of the largest families of flowering plants. If you’ve ever cooked with basil, inhaled the scent of lavender, sipped peppermint tea, or admired a flowering salvia in a pollinator garden, you’ve met this family up close.
Most Lamiaceae species thrive in sunny, dry, open habitats, and many are native to the Mediterranean region—one of the reasons this family includes so many aromatic culinary herbs.
Lamiaceae plants show an impressive range of forms:
Fragrant herbs (mint, basil, oregano)
Subshrubs (lavender, rosemary)
Woody shrubs (salvia species, some basils)
Small trees in certain tropical genera
Despite this variety, they share distinctive traits that make them surprisingly easy to recognize.
Characteristics of the Lamiaceae Family
Lamiaceae plants are among the easiest families to identify thanks to their unmistakable leaves, stems, and flowers.
Leaf Traits You Can Spot
Lamiaceae leaves tend to be:
Opposite (paired along the stem)
Frequently aromatic when crushed
Usually simple, sometimes slightly toothed
Often covered in glands that produce essential oils
Run your fingers across basil or mint leaves—you’ll feel tiny oil glands and smell the potent chemistry that makes this family so beloved.
Stem Characteristics
One of the signature traits of Lamiaceae is the square stem (four-sided).If you roll the stem of mint or sage between your fingers, you’ll feel the edges.
Flower Characteristics
Lamiaceae flowers are typically:
Bilabiate (two-lipped, like a tiny open mouth)
Arranged in whorls or spikes
Built for pollination by bees, butterflies, and hummingbirds
Zygomorphic (symmetrical in only one direction)
The “two-lipped” flower is one of the strongest clues you’re looking at a member of the mint family.
Fruit Types
Most Lamiaceae species produce:
Schizocarps: small, dry fruits that split into four tiny nutlets
These fruits aren’t showy, but they’re botanically distinctive.
Lamiaceae Subfamilies
Botanists classify Lamiaceae into several subfamilies. While the system can be complex, a few major groups are widely recognized.
Nepetoideae
One of the largest subfamilies, known for high concentrations of essential oils. Includes many culinary herbs:
Lamioideae
This subfamily includes more weedy or shade-tolerant species, such as:
Dead-nettles (Lamium)
Horehound (Marrubium)
They’re not as aromatic but are often important medicinally.
Prostantheroideae
Contains many aromatic shrubs from Australia, including the popular “mint bushes.”
Ajugoideae
A diverse group including:
Bugleweed (Ajuga)
Teak (Tectona), a fascinating woody outlier in the family
Major Genera in the Lamiaceae
Mentha (Mint)
Beloved worldwide, mints are vigorous growers with:
Strong scents
Creeping root systems
High essential-oil content
Peppermint and spearmint are the most common species, used in teas, medicine, candy, and aromatherapy.
Ocimum (Basil)
From sweet basil to holy basil (tulsi), Ocimum species define cuisines across the globe:
Italian
Thai
Indian
Persian
Their scent varies widely depending on essential-oil composition.
Lavandula (Lavender)
Known for:
Relaxing fragrance
Purple flower spikes
Drought tolerance
Lavender is used in perfumes, soaps, oils, and ornamental landscapes.
Salvia (Sage and Salvias)
One of the largest genera, containing:
Culinary sage (Salvia officinalis)
Ornamental salvias (“sages”) beloved by pollinators
Many salvia species have spectacular flowers.
Rosmarinus (Rosemary)
Now botanically included within Salvia, rosemary remains a globally important:
Culinary herb
Medicinal plant
Drought-tolerant ornamental shrub
Thymus (Thyme)
Low-growing, aromatic, and tough—excellent for:
Cooking
Rock gardens
Groundcovers
