hoya
Hoyas are semi-succulent, epiphytic plants native to tropical and subtropical Asia, and are in the Asclepiadaceae family, along with milkweed. Hoyas are known for their waxy clusters of star-shaped, fragrant flowers. Some species of hoya look so similar that they can only be easily identified by their blooms.
Light: Bright, indirect light. Hoyas require a lot of bright light in order to bloom.
Water: Allow hoyas to dry almost completely between watering. If leaves appear shriveled or wrinkled and are soft, the plant is thirsty. Thinner-leaved species tend to need more watering than those with thicker leaves.
Humidity: Hoyas thrive in high humidity that mimic their warm, native tropical environment.
Soil: Hoyas do best in lightweight, well-draining potting mix that is similar to what succulents prefer.
Nutrients: Feed hoyas monthly with liquid houseplant fertilizer during the spring and summer. Do not feed in the fall and winter.
Pests/Diseases: Hoyas are prone to mealybugs and spider mites. Treat with neem as necessary. Botrytis and other fungal infections are common in hoyas, especially if overwatered.
Toxicity: Hoyas are considered generally non-toxic to humans and animals.
