Bugleweed loves to dwell in flood-prone areas where it gets to enjoy the goodness of loam, clay, and silt. The seeds are directly sown in the soil as soon as the soil can be worked in spring. Try not to sow bugleweed seeds too deep because they require a generous amount of light to germinate.

Bugleweed requires plenty of water and partial to full sun exposure for proper germination and also after it reaches maturity to spread robustly via its rhizomatous system to form colonies. It is preferred to be grown outdoors as the indoor plantation does not do well and is quite laborious. The seeds need to undergo cold stratification for a month, all the while keeping them moist. Then after the last frost, the seedlings can be planted either outdoors or in a giant-sized pot that mimics a wetland, wet meadow, or shore.

It takes around 8 to 12 weeks for the American bugleweed seeds to germinate. If it is provided with ideal moist, soggy conditions, it can thrive and spread by both stolons and seeds to form colonies.

From July, American bugleweed sets its foot in the blooming phase and continues to produce exquisite clusters of white flowers till September. The tiny white flowers proffer nectar for honeybees and butterflies in return for robust pollination.

After fertilization comes forth a fruit in the form of a set of 4 nutlets, each bearing a single seed. The seeds can then spread in the wild on their own or be saved by humans to be planted again for the perpetuation of the bugleweed life cycle.


Bugleweed should be harvested as soon as the plant starts giving flowers, usually in July. 

Only the aerial parts of American Bugleweed are harvested and the rhizome is left intact to encourage the re-growth of the aerial matrix.
