The ZZ plant (Zamioculcas zamiifolia) is famous for its glossy green leaves, exceptional durability, and ability to thrive in low-light conditions. Because it is primarily grown for foliage, many plant owners are surprised—and excited—when they see a flower bud emerging from the base of the plant. This rarity has led to viral tips online claiming that spraying leaves with special liquids, including beer or homemade solutions, can trigger flowering. But is that really true?

Why ZZ Plants Rarely Flower Indoors

ZZ plants do flower naturally, but this usually happens in ideal conditions and often outdoors or in professional greenhouses. The flower itself is small, pale yellow, and resembles a calla-lily-like spadix rather than a showy bloom.

According to the Royal Horticultural Society, flowering in foliage plants like ZZ plants is a sign of optimal growing conditions rather than a response to quick fixes or surface treatments.

The Viral Claim: Spraying Beer or Special Liquids

Some viral posts suggest spraying diluted beer or other liquids onto ZZ plant leaves to “stimulate growth” or “force flowering.” While beer contains sugars and yeast, there is no scientific evidence showing that spraying beer promotes flowering in houseplants.

In fact, sticky residues from sugary liquids can:

• Attract pests such as ants and fungus gnats

• Block leaf pores (stomata), interfering with gas exchange

• Encourage fungal growth on leaves

The University of Illinois Extension explicitly warns against using sugary household liquids on plant foliage.

What Actually Causes a ZZ Plant to Flower

ZZ plant flowering is typically the result of long-term proper care, not sudden treatments. Key factors include:

• Bright, indirect light (more light increases flowering potential)

• Well-draining soil to prevent root rot

• Moderate watering (overwatering is the most common mistake)

• Stable temperatures and minimal stress

• Balanced fertilization, used sparingly

The Clemson Cooperative Extension notes that healthy root systems and consistent care are the main drivers of flowering in houseplants.

Should You Spray Leaves at All?

Occasional misting with clean water can help remove dust and improve leaf appearance, but it does not directly cause flowering. ZZ plants are drought-tolerant and do not require high humidity.

Any claim that a single spray or homemade solution can guarantee flowering should be viewed with skepticism.

What a Flower Really Means

When a ZZ plant flowers, it usually indicates:

• The plant has matured

• Root conditions are healthy

• The environment has been stable for a long time

Flowering is a bonus, not a goal—and it is not necessary for plant health.

Conclusion

ZZ plant flowers are rare and beautiful, but they cannot be forced with viral tricks like spraying beer or special liquids. True flowering is the result of patience, proper light, careful watering, and overall plant health. When it happens naturally, it’s a sign that you’re doing something right—not that you followed a shortcut.
