Expanding a collection of rare anthuriums is such an exciting journey! In terms of reputable sources, I've had a positive experience with online plant communities and forums. Many fellow enthusiasts are open to trades or can point you towards trusted sellers. Etsy is also a trustworthy marketplace, but as always, do a bit of background research on the seller first.
Anthurium clarinervium is one species I’ve found quite forgiving indoors. Its thick, velvety leaves are resilient if you maintain consistent humidity and avoid overwatering. A humidity tray or regular misting can make a big difference. As for unusual care practices, consider using a diluted liquid fertilizer during their growing season to encourage those vibrant leaves.
Don’t underestimate the value of monitoring your plant’s conditions closely at first. Each home has different environmental factors like light, humidity, and temperature, so what works for one might need tweaking for another. It might be worth investing in a small hygrometer to keep an eye on humidity levels.
Have you considered joining any anthurium-specific groups or societies? They can be great resources not only for purchasing options but for sharing care tips tailored to your local conditions. What rare species are you currently eyeing to add next to your collection?
