Yellow Mandevilla is a perennial vine-like shrub with yellow Allamanda like flowers. The flower color is almost neon yellow throughout. Its foliage is oval, simple (no lobes), glossy and yellowish-green. Sometimes, but rarely, the leaves may be matte with tiny hairs.
Grows as a vine-like shrub when it is young. The light yellow, trumpet-like blossoms appear on the tips of new growth and from side branches on the vine. Flowers bloom almost year-round, although the plant is not covered with flowers like the Allamanda.
Hummingbirds and butterflies will visit the blossoms.
Yellow Mandevilla grows well in average to poor, well-drained soils in full to partial sun. Provide ample moisture, especially from spring to late summer, to prevent leaf drop. It is also drought and salt tolerant.
Yellow Mandevilla makes a wonderful, ever-blooming specimen plant. Grow it as a small vine upon a trellis or allow it to ramble in a mound in the mixed border or as a groundcover among shrubs and rocks.
All parts of plant are poisonous if ingested. Handling plant may cause skin irritation..
