Anthurium

Anthuriums are known for their glossy, heart-shaped blooms, which is why they often steal the spotlight around Valentine’s Day.

But, these tropical beauties deserve attention all year long! Available in vibrant reds and oranges, soft pinks, greens and creamy whites, Anthuriums bring bold color and a modern tropical feel to indoor spaces.

What many people don’t realize is that the “flower” is actually a spathe, a modified leaf that surrounds the true flower. The spike-like structcure the spathe surrounds is called a spadix. The spadix appears in yellow, green & white.

Each bloom can last up to six weeks, making Anthuriums one of the longest-lasting flowering houseplants you can grow.

Here’s how to keep them thriving.

Light

Anthuriums love light, just not harsh sun.

Place plants near a bright, indirectly lit south, east or west-facing window.
Avoid direct sunlight, which can scorch leaves and fade blooms.
Too little light may reduce flowering.

Bright, filtered light helps encourage steady growth and repeat blooms.

Water

Proper watering keeps Anthuriums happy and prevents root issues.

Water thoroughly until excess drains from the pot.
Allow the top inch of soil to dry before watering again.
Always discard standing water from saucers.

These plants prefer slightly moist soil but dislike sitting in soggy soil.

Fertilizer & General Care

Consistent care leads to healthier plants and longer-lasting flowers.

Fertilize once per month with a balanced houseplant fertilizer.
Provide good air circulation around the plant.
Repot annually to refresh soil and encourage growth.
Propagate new plants easily through division when repotting.

Temperature

Anthuriums prefer warm, stable indoor temperatures.

Night: 65–70°F
Day: 75–80°F

Avoid cold drafts, sudden temperature swings or placing plants near heating or cooling vents.

Humidity

Native to the tropical Americas, Anthuriums thrive in humid environments.

To increase humidity:

Place pots on a pebble tray filled with water.
Keep the pot elevated so it does not sit directly in water.
As water evaporates, humidity rises around the plant.

This simple trick can significantly improve plant health and flowering.

Beyond the Blooms

While many Anthuriums are grown for their flowers, some varieties are gaining popularity as foliage plants. Their leaves may feature deep green tones, white variegation or even rosy undersides. Many of today’s largest and most colorful hybrids were developed by growers in Hawaii, expanding the range of shapes and colors available to plant lovers.

Pet Safety

Anthuriums contain insoluble calcium oxalates, which can cause irritation, swelling or vomiting if chewed or eaten. For safety, keep plants out of reach of pets and small children.

Why Grow Anthuriums?

With their glossy leaves, striking heart-shaped blooms and long-lasting flowers, Anthuriums bring a touch of the tropics indoors with surprisingly simple care. Provide warmth, humidity and consistent watering and these plants will reward you with bold color and elegant beauty throughout the year.
