With its bold and colorful leaves, the croton plant is sure to make a statement in any indoor or outdoor space. From its fascinating origins to its diverse cultivars, there is much to uncover about this remarkable species.

Here are 12 interesting facts about the croton plant that will give you a deeper appreciation of these mesmerizing plants:

1. Crotons Come in Striking Colors

One of the most distinctive features of croton plants is their vibrantly colored leaves. Croton leaves come in a kaleidoscopic array of colors like green, yellow, orange, red, pink, purple, black, white, and various combinations.

The specific colors and patterns depend on the croton variety, light exposure, and plant maturity. Young croton leaves tend to be brighter, while older leaves darken to black shades.

2. They Have Numerous Leaf Shapes

Apart from a stunning color palette, croton plants also showcase incredible diversity in leaf shapes and textures.

  • Narrow, ribbon-like leaves
  • Broad, oval leaves
  • Twisted, corkscrew leaves
  • Curling, crinkled leaves
  • Oak-shaped leaves with pointed tips

So whether you prefer slender or wider leaves, upright or cascading plants, there is a croton variety to match your taste.

3. Crotons Are Great Air Purifiers

With their lush, dense foliage, croton plants are excellent air purifiers. They absorb harmful pollutants like benzene, formaldehyde, and carbon monoxide from indoor spaces.

According to NASA research, crotons can eliminate up to 87% of volatile organic compounds in the air. So they not only lend color but also improve air quality.

4. They Thrive in Bright, Indirect Light

To maintain their vibrant foliage colors, croton plants need plenty of light. Ideally, they should get 4-6 hours of bright, indirect sunlight daily. Too little light will result in fewer leaves and faded color.

Place your croton plant near an east, west, or slightly shaded south-facing window. Protect from hot midday sun as it can scorch the leaves.

5. Crotons Prefer Warm & Humid Conditions

As tropical plants, crotons thrive in warm and humid environments. Ideally, daytime temperatures should be 60-80°F and humidity levels around 50-60%.

Cooler temperatures and dry air cause leaf drop in crotons. You can use a humidifier or pebble tray to increase moisture around your plant.

6. They Are Easy To Grow Indoors

Thanks to their tropical origins, stunning foliage, and adaptability to indoor spaces, croton plants make excellent houseplants.

They are quite easy to grow indoors if you can provide suitable warmth, light, and humidity. Their moderate growth rate also makes croton a great low-maintenance houseplant.

7. Crotons Have Medicinal & Cultural Significance

Various croton species have been used in traditional African and Chinese medicine for centuries.

  • Treat digestive ailments
  • Heal wounds
  • Fight malaria
  • Relieve pain

In certain cultures, the croton plant also symbolizes good fortune and prosperity.

8. They Are Toxic If Ingested

While croton plants lend beauty and health benefits, they also contain irritant toxins that can cause issues if ingested.

The sap, leaves, and seeds contain croton oil that can irritate the mouth, digestive tract, and skin on contact. So keep crotons away from pets and children.

9. Crotons Can Be Propagated From Stem Cuttings

As croton plants grow older, their lower leaves shed to reveal woody stems underneath. These older branches can be used to propagate more croton plants.

Take 6-8 inch healthy stem cuttings in spring and root them in water or a well-draining potting mix. Within 4-6 weeks, roots and new shoots will sprout.

10. There Are Hundreds of Croton Varieties

From the popular Petra and Mammy to more unique Banana, Oakleaf, and Twisty varieties, there are over 100 named croton cultivars.

They come in diverse leaf shapes, sizes, textures, and color combinations. Even more varieties are being produced by breeders through hybridization.

11. Crotons Can Flower Outdoors

When grown outside in optimal warmth and light, mature croton plants can produce flowers on long stalks emerging from the upper leaf axils.

The small, star-shaped flowers bloom in summer and fall in green, white, or yellow hues. But indoor croton plants rarely flower.

12. They Make Great Container Plants

With their lush foliage, vibrant colors, and sculptural shapes, croton plants are ideal for containers outdoors.

Use them as:

  • Patio plants
  • Poolside planters
  • Garden borders and edges
  • Striking centerpieces in landscape beds

Place containers in areas receiving 4-6 hours of sunlight. Bring crotons indoors before the first frost.


From its kaleidoscopic foliage to its air-purifying abilities and medicinal value, the croton plant has plenty of intriguing features beyond its ornamental appeal.

Hopefully these 12 facts gave you a glimpse into what makes croton plants so special. Their low maintenance and resilience make them perfect for beginners and busy gardeners alike.
