Jovellana punctata is an unusual rarity from Chile with colorful sprays of happy little flowers! These sprightly blooms appear in large numbers from spring through fall. Its festive markings are purple, yellow and red, with no two flowers having the same pattern. Maybe they communicate something to bumblebees? Or to each other?? This is a cool-climate species that might not thrive in warm areas. It is a very rare plant, and freshly picked seeds are hard to find.
Manihot grahamii / Hardy Tapioca / Graham's Cassava: a native of Eastern South America, from Brazil through to Argentina. I've done a quick web search and this has been successfully grown as far north as North Carolina. (This photo said it was taken in the Pacific NW).
