Growing Tips

To grow motherwort in the home garden, the seeds will need to be stratified for several weeks. They can be sown directly to the garden area. Why not sow the seeds in late fall, allowing the natural winter to stratify them for you?

Motherwort is very forgiving, growing well in all light conditions, and most soils. Be aware that it also self-seeds like a champion, so do not allow it to reseed unless the entire area is given over to this lovely herb. Reduce the chances of it getting away from you by cutting back to 3-5 inches after flowering, but before those seeds mature. Motherwort blooms from mid to late summer and can be harvested anytime.

Motherwort is also an interesting herb for the ornamental landscape. It has a clumping habit and can grow up to 4 ft tall. The leaf structure is very unique, and the purple/blueish flower is a cool, soothing addition to the garden. Divide the roots in fall, and remember that it is in the mint family, so motherwort will reseed and take over if you are not careful.

Harvesting and Storage

The entire herb is harvested after flowering and dried. The dried plant is then made into a tincture, or stored and used as a tea.
