In-Depth Botanical Safety Analysis
Mandevilla (*Mandevilla spp.*), commonly known as Rock Trumpet or Dipladenia, is a genus of spectacular, fast-growing tropical climbing vines in the dogbane family (*Apocynaceae*) that is **highly toxic and chemically hazardous** to both dogs and cats. Celebrated for their showy, trumpet-shaped blossoms in shades of pink, red, and white, Mandevillas contain **cardiotonic glycosides** throughout their tissues and produce a thick, sticky **milky latex sap** when their stems or leaves are broken. This milky latex is highly irritating, triggering immediate contact dermatitis (red, itchy skin rashes) upon physical contact. If chewed or swallowed, the sap causes severe oral burning, swelling of the mouth, hypersalivation (drooling), nausea, vomiting, and diarrhea. The active glycosides can also interfere with cellular processes and affect heart rhythms if consumed in large quantities. Immediate emergency care includes flushing the skin and mouth with water. For a gorgeous, pet-friendly flowering climber, replace Mandevilla with non-toxic choices like the Petunia or Sweet Alyssum.
