Overview of Hoya Kerrii
Hoya Kerrii, often called the Sweetheart Plant or Valentine Hoya, charms plant enthusiasts with its thick, heart-shaped leaves that symbolize love and affection.
Native to Southeast Asia, this Hoya can grow up to 13 feet in the wild but usually reaches 2-3 feet indoors.
Patience is key, as it can take 2-3 years to start blooming. When it does, you'll see star-shaped flowers in colors like white, pale pink, or red.
It's an epiphytic plant, so it can grow on other surfaces and absorb nutrients from the air.
This plant comes in several varieties, including the Sweetheart, Albomarginata, and Splash.
With a little care, you can enjoy its unique beauty and blooms.
Optimal Lighting Conditions
To guarantee your Sweetheart Plant thrives, providing the right lighting conditions is essential. Hoya Kerrii hearts need bright, indirect light for 8 to 12 hours daily, similar to their natural habitat in Southeast Asia.
Place your plant near a south-facing window with sheer curtains to provide ideal lighting conditions without scorching the leaves. If you notice yellowing leaves, it might mean too much light, and you'll need to adjust its placement.

Temperature and Humidity
Ensuring your Sweetheart Plant blooms beautifully involves managing the temperature and humidity with care.
Hoya Kerrii thrives in consistent temperatures between 60°F and 80°F (15°C to 27°C), which are perfect for its growth and flower bud development. It's crucial to keep the temperature above 50°F (10°C); colder conditions can stress the plant and hinder blooming.
Aim for moderate to high humidity levels of 50% to 60% or higher. You can achieve this by misting the plant or using humidity trays.
Stable environmental conditions without drastic temperature fluctuations help promote healthier blooms. Good air circulation is also important to prevent mold and support your Hoya Kerrii's blooming potential.
