This native is a member of the mint family and has clusters of white flowers with lavender spots that bloom in mid-late summer with silvery green leaves that are needle-like.  The plant grows best in full sun and can be aggressive so is ideal for meadows and gardens where it can be confined by hardscape elements.  In 2019, it was selected as the North Carolina Wildflower of the Year.  
Start indoors six weeks before the last frost or outside once the soil is warm.  Needs light to germinate.
