Motherwort (Leonurus cardiaca)

Perennial.
75 seeds per packet.

Traditionally used as a cure for menstrual problems (hence the name) and also used as a heart tonic (scientific name is cardiaca for a reason). Plant grows 4-5 feet tall with cute spires of lavender colored flowers. It can be a bit spiky to handle, so be mindful!
