Oxalis peduncularis

Native from southwestern Colombia to Bolivia, this perennial herb or small subshrub has fleshy stems and three-part leaves. Slender flower stalks rise above the foliage and branch into clusters of yellow flowers. The five petals can show reddish streaks, while the sepals may have purple margins. Plants grow upright or with ascending stems and can reach about 20 inches tall when flowering. It occurs in Andean habitats. Photographed in Colombia.
