Self-heal, all-heal, heal-all, Brunella (Prunella vulgaris)
“Fibrous-rooted perennial from a short rhizome or stem-base; stems solitary or clustered, erect to spreading or even reclining, leafy, square in cross-section, usually unbranched, 10-50 cm long or tall.
Leaves [are] opposite, relatively few, lance-egg-shaped to oblong or elliptic, minutely hairy to hairless, stalked; [leaf] margins smooth or obscurely toothed.
Flowers [are] purplish to pink [...], 1-2 cm long, short-stalked; sepals united in a 2-lipped, spine-tipped tube; petals fused into 2-lipped tube, upper lip hooded and bonnet-like, lower lip 3 lobed (the middle lobe fringed); 4 stamens; 4-lobed ovary; numerous in dense, spike-like cluster atop the stem.”

Collection restrictions or guidelines
Prunella vulgaris is a perennial herbaceous plant that blooms from June through October. Division can occur any time plants are found. In a mild climate, division can take place any time of the year.. Stolon collection can occur whenever rooting stolons can be found.
Seed collection is most easily accomplished by collecting flower heads at the end of their growing season (September, October, November).
Seeds can be sown on-site in densities that are varied according to desired germination and survival outcomes. , 
Plant mortality should be factored into any restoration project using Prunella vulgaris seeds on-site (in situ). 
When seeds are grown in greenhouses or cold frames, they are transplanted (approximately eight weeks ) when they are large enough to handle. 
Germination occurs within two to three weeks. 
Seeds can be stored; I am unable to verify the shelf-life and storage conditions at present.
Recommended seed storage conditions
Unable to verify.
Prunella vulgaris can be propagated by stolon, division, or seed. Propagation by stolon yields larger plants in a shorter amount of growing time. Stolons root wherever they touch soil.
Cold-stratify seeds for approximately one month. 
Seeds can be started in flats, and when the plants are large enough to handle (approximately eight weeks ) they can be transplanted into individual pots and grown to the desired size. Seeds may also be sown directly on site, preferably in late Fall to early Spring. 
Soil or medium requirements
Soil requirements are not exacting.  Prunella vulgaris will grow in sandy soil, volcanic ash soil, loamy soil, and clay soil. Soil moisture requirements range from an average of mesic to a maximum of hydric.  Once established, Prunella vulgaris can tolerate xeric conditions found late-season in Mediterranean climates. 
Seeds can be sown on site, however the best strategy for a successful installation is to transplant plants with six or more leaves. 
Recommended planting density
Typical forest edge density is
approximately three to ten plants per square meter at 800 meters elevation near
Mount Rainier/White Pass (
Around sunny forest edges where the soil is extremely well-drained (pumice and volcanic ash), three plants (groupings of plants approximately 10 cm across) per square meter is average. 
Care requirements after installed
Prunella vulgaris should not be allowed to dry-out during its first growing season. Soil should be kept barely moist to damp in partially-shaded plantings, and moist in full-sun plantings. It is best (in the Pacific NW) to plant during the winter rainy season. 
After plants are established, high soil moisture will cause increased (even weedy) growth. Established plants can tolerate extended dry periods  but do best when soil is consistently moist enough to prevent roots from drying out.
Normal rate of growth or spread; lifespan
variable growth rate. Under cultivation and ideal conditions
(observed without the addition of any fertilizers), plants can spread
approximately 45 cm in a growing season.
In the grand fir (Abies grandis) forests near
Prunella vulgaris is a perennial that can remain evergreen in mild climates. , , 
A single plant may live from three to ten years. 
Plants spread most aggressively/primarily via stolons.
