Hoya Sweetheart (Hoya kerrii) is a charming succulent vine from the tropical forests of Southeast Asia, including Thailand, Vietnam, and southern China. Part of the Apocynaceae family, this beloved heart shaped plant has won over collectors and casual plant lovers alike as one of the most recognizable easy care houseplants around.
The Hoya Sweetheart is instantly recognized by its thick, waxy, perfectly heart-shaped leaves in a rich forest green that practically glows in bright indirect light. Each leaf is firm and slightly succulent, holding moisture beautifully and giving the plant a sculptural, architectural quality. Mature vining plants develop long trailing stems that look stunning cascading from a hanging basket or draped over a shelf.
Given the right conditions, including a slight drop in nighttime temperatures, Hoya Sweetheart can reward patient growers with clusters of tiny, star-shaped flowers in creamy white to pale pink, often with a sweet, subtle fragrance. Blooms tend to appear on mature specimens during warmer months, making a flowering Hoya Sweetheart a genuinely exciting moment worth waiting for. This plant is pet friendly, so you can display it anywhere in your home without worry.
Hoya Sweetheart thrives near kitchen moisture, appreciates being rotated regularly for even, balanced growth, and does best away from air conditioning or heating vents that blast dry air directly onto its leaves. Come summer, you can move it outside to a sheltered spot where it soaks up the warmth and humidity. A mature specimen displayed in a hanging basket delivers a bohemian, lush look, while a single-leaf starter plant makes a sweet and meaningful gift. Hardy enough to survive a 10-day trip alone without watering, the Hoya Sweetheart is as low maintenance as it is lovely.

Hoya Sweetheart is a moderate grower; feed monthly in spring and summer with a balanced liquid fertilizer diluted to half strength.
Hoya Sweetheart is hardy in USDA Zones 10-11, where temperatures rarely dip below 30-35°F (around 0°C), and can be grown outdoors year-round in those regions. In the United States, that includes Hawaii, southern Florida, and frost-free pockets of southern California and far southern Texas. Gardeners across Arizona, Nevada, Georgia, Louisiana, Mississippi, Alabama, South Carolina, Oregon's coastal zones, and much of the broader Southeast will love growing Hoya Sweetheart as a container plant that moves outside for warm months and comes back indoors before any cold snaps arrive.
