No, your anthurium does not need a lot of sun. Your anthurium sunlight needs are simple: bright indirect light, not direct sun. A spot near a window where the light is strong but filtered gives your plant the glow it needs to bloom without burning the leaves.
I found this out the hard way with my first anthurium. I placed it on a south-facing windowsill thinking more sun meant better growth. Within three weeks the leaves had brown scorch marks all over them. I moved the plant about three feet back from that same window and hung a sheer curtain over the glass. The difference was stunning. New leaves came in glossy and green within a month and the plant started blooming again shortly after.
The reason anthuriums prefer filtered light goes back to how they grow in nature. They grew as epiphytes in the tropical forests of Colombia and Ecuador. They cling to tree branches high above the forest floor. Up there they get dappled light that passes through a thick leaf canopy above them. Direct sun never hits them in the wild, which is why your home needs to mimic that same shaded-but-bright setup.
Your anthurium light requirements depend a lot on window choice. An east-facing window gives your plant gentle morning sun that won't burn the leaves. A west-facing window works too if you filter the stronger afternoon rays with a thin curtain. NC State Extension lists partial shade as the best condition for anthuriums. North-facing windows can work, but your plant may bloom less often because the light is weaker on that side of your home.
A bright indirect light anthurium setup means a "bright glow" fills the room with no harsh sun patches on the leaves. You want the room to feel well-lit but without any direct beams landing on the plant itself. Think of the light level you'd need to read a book by the window without straining your eyes. That's about right for your anthurium to grow strong and push out blooms on a regular cycle. Most rooms with a window nearby hit this mark just fine.
You can test your light levels at home with a quick shadow check. Hold your hand about 12 inches above the spot where your plant sits during the brightest part of the day. If you see a sharp, dark shadow, the light is too strong and direct for your anthurium. A soft shadow with fuzzy edges means the light is filtered and just right. No shadow at all means the spot is too dark and your anthurium won't bloom there, though it may survive with green leaves only.
If your anthurium sits in a spot that's too dark, you'll notice the stems stretching long and thin as the plant reaches for more light. The leaves may also lose their deep green color and the blooms will stop coming. Move it closer to a window or add a grow light running 10-12 hours a day to fix this problem. I use a simple LED grow light during winter months when daylight hours shrink and my anthuriums keep blooming right through to spring. A good grow light costs about $20-30 and makes a huge difference for any tropical plant in a darker room.
Getting the anthurium sunlight needs right is the single biggest factor in whether your plant blooms or just sits there with green leaves. Once you find that sweet spot of bright but filtered light, your anthurium will reward you with those iconic waxy blooms month after month. It took me a few tries to find the perfect spot in my home, but once I did, the results spoke for themselves.
