Our mystery seeds from last week were from a vine commonly called queen’s wreath or coral vine, scientific name Antigonon leptopus.
Queen’s wreath is known for its heart-shaped leaves and showy pink flowers.
It is a perennial plant that is native to Mexico and South America. In case you’d like to grow it, queen’s wreath is listed as an invasive plant in Florida and in a few other countries.
Queen’s wreath belongs to the buckwheat family, Polygonaceae.

Do you think the seeds look like the buckwheat seeds? I can see some similarities in the triangular shape.
