Heart hoya plant, also known as Valentine plant or sweetheart wax plant, is a type of Hoya appropriately named for its thick, succulent, heart-shaped leaves. Like other Hoya varieties, the sweetheart hoya plant is a stunning, low-maintenance indoor plant
This Valentine hoya tolerates relatively low light, but not full shade. However, the plant performs best and is more likely to bloom in bright or indirect sunlight. Room temperatures should be maintained between 60 and 80 F. or 15 and 26 C.
With its fleshy, succulent leaves, sweetheart hoya is relatively drought-tolerant and can get by with as little as one or two waterings per month. Water deeply when the soil is slightly dry to the touch, then let the pot drain thoroughly.
