Mandevilla boliviensis, of the Apocynaceae family, is a tropical vine with trumpet-shaped blooms. The mandevilla is hardy to USDA zones 10 and 11. Since it cannot tolerate the cold, it is often grown as a houseplant. If grown indoors, keep the plant in area that gets at least partial sun and is above 65 degrees. Cut back the plant by one-third in February or March to stimulate new growth. Just like African violets, mandevilla requires high phosphorous fertilizer.
Keep the mandevilla plant away from children and pets as it is poisonous if ingested.
