Goatweed (Hypericum goyanesii)
Description
Hypericum, also known as St. John's wort or goatweed, is a genus of flowering plants in the family Hypericaceae. The genus is distributed around the world, missing only from tropical lowlands, deserts and polar regions. Many Hypericum species are considered invasive species and noxious weeds and are eradicated from certain areas. There are over 490 species in the genus. Hypericum species are quite variable in habit, occurring as trees, shrubs, annuals, and perennials. Trees in the sense of single stemmed woody plants are rare, as most woody species have multiple stems arising from a single base. Shrubs have erect or spreading stems but never root from nodes that touch the ground. Annual herbs tend to have taproots with a developed system of secondary hair roots. Many species of Hypericum are completely glabrous, others have simple hairs, and some species have long, fine hairs.
