Common St. John's Wort (Hypericum perforatum)

A packet contains 1/5 teaspoon of seed, ~640 seeds. 2020 germination test results 62%

Pretty yellow blooms on a medium sized perennial herb that can alternately crawl or stand tall. Used medicinally both internally and externally. Use internally with caution if using any medications, for some reason this plant interacts with a huge number of medicines. Externally the partly-dried flowers are often infused in oil, which turns a pretty amazing shade of red. The species name perforatum refers to the little "holes" you can see in the leaves of this species if you hold them up to light, they are actually oil glands. Can be dispersive by seed, so harvesting all the flowers or deadheading plants is recommended, do not abandon. Hardy to zone 4.
