Cestrum thyrsoideum, commonly known as Longtube Jessamine or Firecracker Jessamine, is a semi-evergreen shrub native to the understory of tropical forests in the Americas. It exhibits a moderate growth rate, reaching heights of 6-9 feet (1.8-2.7 meters) and a spread of 4-5 feet (1.2-1.5 meters). The plant is characterized by its tubular yellow or orange flowers, which are particularly showy and bloom profusely in the spring and summer, attracting hummingbirds and other pollinators. The foliage is dense and provides a lush backdrop for the vibrant flowers.

Longtube Jessamine is valued for its ornamental flowers and ability to attract wildlife. It is used in tropical and subtropical gardens for border planting, as a specimen plant, or integrated into mixed shrub borders. It thrives in full sun to part shade and prefers medium draining loam or clay soils. While it requires medium amounts of water, it is somewhat drought-tolerant once established. This shrub is not known for significant problems with diseases or pests, but it can be sensitive to cold temperatures and may require protection in cooler climates. It is also important to note that all parts of the plant are toxic if ingested, so caution should be exercised in gardens with pets or small children.CC BY-SA 4.0
