Carefree slender vine with large heads of bright yellow flowers resembling oncidium orchids. Blooms profusely spring to fall. The flowers are reminiscent of those of the Lagerstroemia in form, each petal expanding abruptly from a narrow basal claw. They measure a little over 1in across and are brilliant yellow in color. It thrives in sun or light shade and well drained soil, with moderate watering.
