The Basics of Anthurium Flowers
Anthuriums belong to the Araceae family and originate from Central and South American rainforests. There are over 1000 species, but a popular one is Anthurium andreanum, which has glossy green leaves and vibrant spathes in shades of red, pink, orange and more
The spathe is a specialized leaf that surrounds the spadix, which contains the tiny true flowers. Together, these structures create the colorful “bloom” anthuriums are prized for.
What Determines Anthurium Flower Longevity?
Anthuriums can bloom all the time if they are well taken care of; each spathe usually lasts two to three months. But various factors affect individual flower lifespan:
-
Light – Bright, indirect light provides energy for blooming. Insufficient light means fewer or no flowers.
-
Temperature – Ideal temperatures are 70-90°F. Outside this range, flowers fade faster.
-
Humidity – Anthuriums prefer 60%+ humidity. Lower humidity causes blooms to dry out quicker.
-
Water – Too much or too little water stresses plants, resulting in poorer flower quality and longevity.
-
Nutrients – Adequate fertilization gives blooms the energy they need. Lack of nutrients causes weaker flowers.
-
Care – Proper techniques like pruning, repotting and pest management keep plants vigorous for longer-lasting blooms.
Caring For Anthuriums to Maximize Flower Longevity
Your anthurium could have up to six blooms a year, with each one lasting two to three months if you give it the best care that fits its needs. Here are some tips:
-
Provide bright, indirect sunlight from an east or west window. Avoid direct sun.
-
Maintain temperatures of 70-90°F. Avoid cold drafts.
-
Increase humidity to 60% or more. Use a humidifier or pebble tray.
-
Water thoroughly when top 1” of soil is dry. Allow water to penetrate roots.
-
Fertilize monthly with diluted balanced liquid fertilizer during spring and summer.
-
Prune dead leaves and spent flowers to improve plant health.
-
Repot when roots fill the container into a size larger pot with well-draining soil.
-
Monitor for pests like aphids, mealybugs and mites. Take action if found.

Common Pests
These plants are subject to the same pests that commonly affect most houseplants: mealybugs, spider mites, whiteflies, and scale. Aphids leave distorted mottled leaves over time. Ants are a also sign of aphid infestation and feed on the aphids sticky residue.
Spider mites, thrips, and mealybugs also feed on new growth causing yellow stippling and mottled leaves. Stubborn insects may respond to horticultural soap or oil sprays, which are natural and dont harm the plant.
You can often control insects naturally with blasts of water, which dislodge and drown the pests.
Water
Keep soil slightly moist and never allow it to dry out completely. Water indoor plants about once a week or when the top of the soil is dry to the touch. Water your plant until it runs from the pots drainage holes but do not leave it to sit in water—anthuriums are vulnerable to root rot.
Grown outdoors, plants may need water every two to three days.
