What Is Star of Bethlehem and Where Does It Come From?
Hippobroma longiflora, commonly known as Star of Bethlehem, is a perennial herb with an erect or decumbent stem, native to Jamaica and now naturalized in humid tropical and subtropical regions, typically along stream banks and ditches. Its leaves are simple, alternate, elliptical to lanceolate in shape with serrated edges, measuring 5 to 15 cm in length. The flowers are solitary, white, and fragrant, with a slender floral tube 6 to 12 cm long ending in five pointed lobes—an adaptation for pollination by long-tongued sphinx moths. It is considered one of the most dangerous plants to cultivate: the entire plant, especially the milky sap, contains pyridine alkaloids such as lobeline and nicotine. Contact with the sap causes intense burning on the skin and mucous membranes and can cause temporary blindness if it reaches the eyes; ingestion is dangerous for humans and animals (including cattle, dogs, and cats), potentially causing vomiting, tremors, muscle paralysis, and, in severe cases, death.
How to Propagate Star of Bethlehem?
Propagation by seeds
- Always wear gloves when handling capsules and seedlings—the sap is caustic even in young plants.
- 1 Seed collection
Harvest the ellipsoid capsules when they are dry and open on the plant, always using gloves.
- 2 Sowing
Distribute the seeds shallowly, about 0.5 cm deep, in a light substrate rich in organic matter.
- 3 Humidity and warmth
Keep the substrate moist and in a warm place (around 21°C) until germination, which occurs in 10 to 14 days.
Materials needed:
Propagation by cuttings
- Avoid direct contact of the sap with skin during cutting.
- 1 Cutting the stem
Cut a healthy stem segment 10 to 15 cm long, always using protective gloves.
- 2 Planting
Insert the cutting into a moist peat and perlite mixture, leaving at least one node buried.
- 3 Rooting
Keep in a shaded and humid location until rooting, in 2 to 3 weeks.

What Diseases Commonly Affect Star of Bethlehem?
TLDR: Star of Bethlehem is susceptible to 6 known diseases. Monitor regularly for early detection.
Spider Mites
Spider mites are tiny arachnids (less than 1/20 inch long) related to spiders and ticks that feed on plant sap. They thrive in hot, dry conditions and can cause significant damage to ornamental and vegetable plants. During severe infestations, crop losses can reach 14% or higher as these pests disrupt vital plant processes including photosynthesis, carbon dioxide absorption, and transpiration.
Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.
Whiteflies
Whiteflies are small, soft-bodied, winged insects closely related to aphids and mealybugs. They are moth-like in appearance, about 1/16 inch long, triangular in shape, and gray-white in color. These sap-sucking pests feed on plant tissue, causing yellowing, stunted growth, and wilting. They also excrete honeydew, which attracts ants and promotes sooty mold growth. Whiteflies can transmit serious plant viruses.
Powdery Mildew
Powdery mildew is a common fungal disease caused by various fungi species including Erysiphe, Podosphaera, Oïdium, and Leveillula. It affects over 10,000 plant species worldwide. The disease thrives in warm, dry climates with high humidity and appears as a distinctive white powdery coating on plant surfaces.
Meaning & Symbolism
Its star-shaped white flowers evoke purity and light, but the plant serves as a reminder that beauty can hide danger: it is one of the most toxic herbs in the garden.
