COMMON SELF-HEAL
Prunella vulgaris
Brief Summary
Common Self-heal is a rugged, low-growing perennial herb belonging to the mint family (Lamiaceae). Easily recognized by its square stems, opposite leaves, and compact, beehive-like spikes of hooded purple flowers, this globally famous botanical workhorse combines deep historical medicinal value with exceptional adaptability, flourishing beautifully across Northern California's damp montane meadows.
Brief Summary of Floral Composition
The inflorescence is a dense, terminal, spike-like cluster made of multi-flowered whorls (verticillasters) tightly subtended by broad, kidney-shaped green bracts with hairy margins. Each individual flower is bilaterally symmetrical (zygomorphic) and ringed by a two-lipped, purplish calyx. The corolla tube splits into a broad, concave, hood-like upper lip and a 3-lobed lower lip featuring a finely fringed central lobe. Hidden safely inside the upper hood are 4 stamens (arranged in two unequal pairs with unique, pronged filaments) and a single central pistil with a deeply 2-cleft style.

Key Characteristics
The Layered, Beehive Spikes: The most defining feature is its dense, square-angled, cylindrical flower spike at the top of the stem. The spike is composed of tight, overlapping, reddish-green bracts that resemble a miniature pinecone or beehive, out of which the individual flowers erupt.
Two-Lipped Purple Flowers: The small, tubular flowers are a rich violet, lavender, or purple. The upper petal forms a hooded, helmet-like structure that protects the pollen, while the lower petal splits into three fringed lobes, providing a perfect landing pad for insects.
Square Stems & Opposite Leaves: True to the mint family, the stems are distinctly four-sided (square) and slightly hairy. The leaves are ovate to lanceolate, lance-shaped with smooth or shallowly dented edges, growing in a neat, opposite pairing along the stem.
Prostrate to Semi-Erect Habit: It is a creeping perennial herb that spreads via underground runners (stolons) but shoots up erect flowering stems typically ranging from 4 to 15 inches tall.
Notable Significance
The Ultimate Folk Medicine: As its names "Self-heal" and "Heal-all" imply, this plant has a legendary global history in herbal medicine. It contains high levels of rosmarinic acid, tannins, and volatile oils, giving it powerful antibacterial, antioxidant, and astringent properties. Historically, it was a vital poultice for stanching wounds, treating sore throats, and reducing fevers.
Edible Component: The young leaves and stems can be eaten raw in salads, boiled as a potherb, or dried and brewed into a refreshing, health-boosting herbal tea.
Bumblebee Magnet: The hooded floral architecture is perfectly adapted for bumblebees and long-tongued solitary bees. When a bee lands on the lower fringed lip and pushes inside for nectar, the hooded upper lip brushes pollen onto the bee's back.
Locations Found
Habitat: Exceptionally versatile and moisture-loving. It thrives in damp, open environments including moist mountain meadows, lawns, open woodlands, river and stream banks, and roadside ditches.
Local Context: Prunella vulgaris is a cosmopolitan species, with both a native subspecies (subsp. lanceolata) in North America and an introduced European strain (subsp. vulgaris). In the 96063 area, it is incredibly common in mid-summer, carpeting the rich, damp, snowmelt-fed meadow borders and grassy clearings around the southern Cascades.
In preparation for the Wildflower Festival, we've been photographing the wildflowers around Mineral. Watch the album where we're keeping them to see how they progress throughout the season. We'll have a sheet with names and photos for the day of the Wildflower Festival. "I know the names of the flowers, but forget them, if I don't use them," says Stephanie Dennis. "That's why having an annual Wildflower Festival could be helpful. I've been noticing the little flowers more than ever since preparing for the Festival," added Lisa Chandler.
