Hoya obscura (silver)​

Purchased cutting from Jackie May 29, 2026

• Light Requirements - The Hoya obscura thrives in bright, indirect light – think an east or south-facing window. While it can tolerate some direct morning sun in winter, scorching summer rays are a no-go. If you don’t have an ideal window spot, no worries! A grow light set up about 6-12 inches away for 12-14 hours per day can provide the perfect amount of brightness.
• Watering Needs - One of the biggest perks of this plant is how forgiving it is when it comes to watering. The Hoya obscura’s drought-tolerant nature means it only needs a good soak once a week in spring and fall. In the summer when it’s actively growing, give it a drink 2-3 times per week. The trick is letting the top 2 inches of soil dry out between waterings to prevent rot.
• Soil - These tropical plants crave a well-draining soil mix to prevent issues like root rot. A good blend is a chunky potting mix combined with ingredients that add airiness and drainage like peat moss, perlite, pumice or lava rocks. Aim for a mix that dries out a bit between waterings but still retains some moisture.
• Fertilizer - Feed your Hoya obscura every 2-4 weeks during the spring and summer growing period with a balanced, water-soluble fertilizer diluted to half strength. Look for one high in nitrogen to promote lush, green growth. In the winter months when growth slows, hold off on fertilizing until spring.
• Climate - Originally from the humid tropics, the ideal environment for a Hoya obscura is 60-75°F with 70-80% humidity. Don’t worry if your home isn’t that humid though – these plants can still thrive in average household conditions. Just be sure to avoid drafts, dry air from heaters/AC, and cold temps below 50°F.
