Redwing. Ones first impression when seeing this plant is rather befuddling. Because it has yellow flowers and seed along side them which resemble maple seed. It is native to southern Brazil, northern Argentina and surrounding countries. One might also have a hard time deciding whether it is a vine or a shrub. It's kind of a cross between both. More like a rambling rose. But both its flowers and its seed are quite ornamental, with flowering starting in early summer and continuing into the fall. The flowers and seed are seen simultaneously. Give it full sun for best flower, but it will also perform well in part shade. It does well in almost any soil, just don't give it wet feet.
