Yellow allamanda is native to tropical America and blooms from May to June. It gets its name because its flower color and appearance are very similar to yellow allamanda. Yellow allamanda has high ornamental value and is now often grown as a potted plant for display in halls, and it can also be seen in park flower beds.

Yellow Allamanda

Yellow allamanda produces fruit after flowering; the capsule has soft spines, and the seeds are winged. The seeds should not be stored for long and are best sown immediately after collection. One-year-old seedlings can be released from the nursery. In production, cutting propagation is mostly used. From late March to mid-April, after the temperature steadily rises, cut half-year-old to 2-year-old branches as cuttings and insert them densely into wet sand or vermiculite beds, spraying to maintain moisture. When the temperature is above 20 C, roots can develop in about 20 days, and after about 40 days they can be moved to nursery beds for cultivation or potted. Nursery seedlings can be released the following year and bloom for viewing. After pruning, 2-year-old yellow allamanda seedlings can sprout multiple branches, forming a full crown and producing more flowers, entering the peak ornamental period.
