Look low, where the grass grows wild and tangled. Spot the tidy, purple-topped spikes rising from a mat of green.
🌐 WHERE
Widespread across temperate regions; grows in meadows, lawns, woodland edges, roadsides, disturbed ground.
⌚ WHEN
Prunella blooms July to September and sometimes into early October. Leaves can be spotted almost year round, and it can be fun hunting them without the blossoms to guide you. Harvesting this plant for tea is generally done while in flower.
🌿 ENGAGE 🌿
Feel the square shape of the stem by gently rubbing it between thumb and fingers.
Count how the leaves pair up along the stem’s ladder.
Gently examine the flower head—notice how the tiny florets cluster in a ring. See if you can find at least one head without any purple.
Follow the fuzzy leaf edges with your fingertip. What would you call this shape?
Sit beside a cluster of Prunella and see what else shares its lowly space.

🌿 TRY THIS: 🌿
Sketch the flower from different angles.
Record what other plants grow alongside it.
Analyze its structure—how does its shape relate to pollinators?
Bonus: Try “Mapping the Mat” – draw or photograph all visible species in a 1-foot square where Prunella grows. Use the “Seek” app by iNaturalist to identify any species you don’t yet know, and spend a little time learning something special about each one.
[from the old “Jo Journey” – July 19th, 2023]
I use this herb more than any other, in part because of its immunity-boosting properties, but also because it grows abundantly where I live and is easy to identify, harvest, store, and use.
Prunella vulgaris is called “heal-all” because it has been used for so long to help so many different ailments. As mentioned, I use it because it boosts the immune system and also has nutritive value. I add a pinch of my dried, self-harvested Prunella to almost every tea bag I make. My Mate even knows it as “that plant we add to every tea”. :wink:
I harvest Prunella when it is in flower, gathering the above-ground parts from select locations around the property. Sometimes it is ready earlier than mid-July, but this has been a rainy year (2023), and the Prunella here are just beginning their lengthy flowering season. I have harvested them from our yard here in eastern Michigan as late as mid-October. The fact that it blooms right here on the property where I live — for three whole months or more — makes it easy for me to gather enough for the whole year, using the bulk of it in the winter months when we drink tea EVERY day. :D
After I finish gathering Prunella, I remove the softer parts from the toughest main stems, and set them out to dry for several days. You CAN use the main stems, but I remove them simply because I have plenty dried herb without them.
