Imagine a world in which the oceans are filled with purple algae, and forests are swaying in blue-colored leaves. Of course we’re not talking about something from a science-fiction book, either.
It is a common belief that all life forms must be green. This is due to the fact that plants produce energy through chloroplasts. Chloroplasts comprise chlorophyll and chlorophyll is green.
Begonia pavonina, also known as Peacock Begonia, Sedum Blue Pearl, Silver Sword Philodendron, Blue Agave, Blue Hosta, Crassula Ovata Blue bird’ as well as Cebu Blue Pothos are all examples of blue leaf houseplants. The blue leaf is due to special photonic crystals that are able to more efficiently absorb solar energy.
The results of research show that the first photosynthesis organisms were violet because they utilized photosynthetic chemicals that absorb light at various wavelengths.
What Causes Blue Leaves on Plants?
The Begonia pavonina, also known as peacock begonia, usually has vibrant blue leaves in addition to the more typical green leaves.
Scientists at Bristol University University of Bristol wrote in Nature Plants ( Source) that the begonia required blue leaves as they better absorb the light required to produce photosynthesis. This is particularly important in the case of B. pavonina that grows in the shade of the trees of Malaysian forests.
It is known that plant cells absorb sunlight through organs within their cells, which are known as chloroplasts.
These tiny organelles, referred to as chloroplasts, are the places plants keep their chlorophyll.
In the begonia B. pavonina, the chlorophyll stacks do not appear randomly , as in other plants, but instead form photonic crystals.
The blue hue of the leaves of begonia pavonina is due to the photonic crystals. The most important aspect is the fact that chlorophyll of this type is better able to absorb the red and green light frequencies.
Thus, B. pavonina receives 10 percent more energy than its peers, which aids them in growing in the lower forests floors.
Indoor Plants With Blue Leaves
2. Blue Agave
The cultivation of an agave blue (lat. Agave Tequilana) isn’t hard if there is the space.
It can also reach the size of 5 feet (1.5 millimeters) indoors. It also has spines along their edges which could cause serious injuries when handled with carelessness.

Blue agave is indigenous to Mexico and is on the wild side in states like Sonora, Sinaloa, Jalisco, Michoacan, and Oaxaca.
The states are located in the southwest of the nation, which is close to the Pacific Ocean. It is thriving at altitudes of 3000 and 6500 feet (900 and 2200 metres) above sea levels.
Blue Agave Care Indoors
- The container was not very deep, but it was it was wide. The most popular material for pots is ceramic.
- Lighting – plentiful. Plant vases on the south-facing side. In the event of a short day it is recommended to add some lighting to the bushes by using LED lamps during winter.
- Make sure you get lots of air freshener.
- Moderate watering in summer, once a week, and in winter it is enough to wet the soil each 25-30 day.
- Soil – sandy with an abundance of drainage. Alkaline soils are the most preferred.
- Replant each three years.
3. Silver Sword Philodendron
The large and glossy leaf of the sword made from silver Philodendron ( Philodendron hastatum) are a touch of silver and blue on their surface.
Tropical South and Central American rainforests are the home of the plant’s habitat in its natural form.
Even with the most effective treatment even with the best care, even with the best care, Silver Sword Philodendron only grows to about 15 inches at home. Although it’s small but it still requires support.
If you put a tiny flowering plant on a window sill facing either east or west it appears to shine with a blueish silver hue.
If there is insufficient illumination in the area, it is possible that the Silver Queen crown will appear bright green.
Silver Sword Philodendron prefers it when the soil is dry completely between irrigations.
The top 1-2 inches of soil are dry to the touch , but don’t over-water.
If the leaves are dried too long and lose their turgor, they will fall off which makes them hard and susceptible to fall off.
Use soil mix that is well drained. Add Coarse coconut fiber, bark, or moss are all alternatives.

4. Sedum Blue Pearl
Sedum Blue Pearl is a elegant, chic, and bright beauty.
The mature plant can reach up to heights of 6-8 inches and a length of 13-15 inches. It produces a dense carpet of leaves that are a vibrantly smokey blue, with a purple-burgundy hue and huge inflorescences that are vibrant pink.
It can make the background of any composition look amazing when juxtaposed against it. Additionally, it is able to endure harsh winters.
Family Crassulaceae includes Sedum, a genus that includes around 350 varieties of long-branched, semi-shrubs with herbaceous leaves that grow along the ground.
Mexico, Africa, Asia, North America, and Europe are the main habitats for species belonging to this genus.
There is a remarkable variety of sedum species found in Mexico. Sedums are great honey plants that attract numerous bees and other insects to the gardens.
5. Blue Hosta
The waxy layer on the leaves give the blue hosta an unusual hue of blueish-blue. It could also be adorned with stunning blue-green variations.
If you place the plant exposed to direct sunlight for a long time, the blue wax layer will begin to peel away, leaving the plant to appear light green.
The blue hostas’ leaves are what makes them visually attractive. The flowers they produce aren’t very attractive. They’re bell-shaped and are sown on sturdy, long stalks of flowers.
It is able to thrive in any setting regardless of the lighting conditions. The best part to note is the fact that this species favors shaded and semi-shady areas.
The bluish-colored coating that develops on the leaf surfaces will become more noticeable in this area. It is most at ease under areas of shade as well as on the north-facing side of structures.

The hosta’s blue hue contrasts beautifully with the green foliage of coniferous trees.
Planting And Growing Conditions
- It must have some shade to allow the leaf covering to look gray-blue. The leaves of the plant turn green when the sun shines on them.
- The hosta should be placed near tall plants, like trees or bushes. The soil should have a good drainage, be moist, and rich in humus and acidic. Hostas are not a good choice for clay or sandy soils.
- Apply fertilizer after the soil has been loosened by 12 to (30 centimeters).
- Create a hole in the loose soil. In other words the width and height are the same as its rootball.
- When you plant the root ball, the top of the root ball must be on the same level as the ground.
- They are spread out carefully , and then covered with soil.
- The soil surrounding the plant’s base is compacted and then is covered with bark shredded;
- Make sure that the plant is supplied with plenty of water.
- Be sure that the area you are planting isn’t being blown about by powerful winds.
6. Cebu Blue Pothos
The blue-green, arrow-shaped leaf of the Epipremnum ( Epipremnum pinnatum“Cebu Blue”) don’t show any indication of variegation.
The metallic sheen of leaves differentiates this species from other species.
The leaves that are young from Cebu Blue have a shape like an arrow and the mature leaves of the plants are huge blue-green and split in the same manner the leaves of monstera are.
The plant requires time to develop in a well-lit, warm location for the leaf to develop.
7. Crassula Ovata “Blue bird”
The leaf leaves on Crassula Blue Bird are curly and have curly edges. This differentiates this Blue Bird cultivar from other cultivars. This is why many refer to this plant as “curly crassula.”
As with most jade plants this Succulent is a slow-growing one. However, its most distinctive feature is its striking shade combination of green, blue, and red.
The largest flower can reach 50 centimeters in height However, a tiny pot will prevent it from becoming too large.
