Ever walk into a room and notice little plant-like decorations? You ask the host where you can get a piece or two to decorate your home, and they mention that they are actual plants. If you are not familiar with the Tillandsia plants, you would probably think they are pulling your leg. These air plants grow without soil. How?

It is pretty perplexing to a newbie without an idea how air plants survive. They can live without soil. The dirt will suck the life out of these extraordinary beauties. The atmosphere around them supplements their every nutritional need- food, air, and sunlight.

Factors that Affect the Lifespan, Growth, and Size of Air Plants

These cuties come in differing colors, shapes, and sizes, making them favorable to place on any staging you wish. Be it on a geometrical model, a hung metallic frame, or a simple glass tabletop terrarium. You may even include one variety or two as part of your fairy garden. Below, I list 3 factors that I personally think are important in your air plants’ growth.

#1. Environment

Air plants are native to tropical regions of Central and South America, where they grow in humid forests and rainforests. To help your air plants thrive, it’s vital to assemble their natural environment. Please keep them in a warm, humid location with good air circulation. You should keep them away from direct sunlight, air conditioners, or heating vents.

#2. Watering Schedule

People should avoid overwatering or underwatering with air plants (or any low-maintenance plants). Air plants absorb moisture through their leaves, so they don’t need to be frequently watered as traditional plants. For short, it’s recommended to soak air plants in water for 20-30 minutes weekly. However, the watering schedule may need to be adjusted depending on the humidity of your environment.

#3. Overall Care

To keep your air plants healthy, providing them with the proper care is essential. This care includes regular cleaning to remove dust and debris, trimming dead leaves, and occasionally fertilizing with a water-soluble fertilizer. It’s also essential to avoid exposing air plants to chemicals or pesticides, as they can be sensitive to them.

How Big Do Air Plants Get?

Air plants come in various sizes, from tiny specimens that are only a few inches tall to larger plants that can be several feet tall. The size of air plants can vary depending on the species, growing conditions, and plant age. Air plants will grow to their full size within a few years of maturity.

For further details, you must familiarize yourself with the exact size each grows so that you know the best location to place them. Every species germinates from a seed, then a seedling, then a fully grown plant. But the question we are to answer today is how big they grow. And the best way to do so is to look at the most significant kinds in the Tillandsia family.

#1. Bulbosa

This air plant has long wave-like dark green tendrils originating from the bulbose base and meandering outwards. The thin flat leaves resemble the crop of an under-the-sea creature because of their unique winding nature that grows freely in all directions. The leaves at the base of the plant are usually highlighted with an attractive hue of plum and will yield a bright red bloom and bright violet petals when it flowers.

This crop originates on the wild sides of the Caribbean basin and Central America. It loves the humid air found in such regions. These Bromeliad epiphytes use their tiny roots to anchor themselves on any surface. Therefore, they grow on trees and rocks with plenty of direct shaded light.

A full-grown Tillandsia Bulbosa produces large bulbous bases ranging between 2 to an astounding 9 inches in circumference and 18 inches in height. Their narrow, curled-up leaves can spread to a length of 8 to 10 inches. Due to their larger size than other air plants, they do best when grown in open structures such as open frames and unconstricted containers.

#2. Caput-Medusae

If you are familiar with the Greek mythological story of Medusa, you will recall that her head was filled with live snakes. And this air plant appears as this name suggests. The snake-shaped green leaves bring an exotic flair to any surface on which this crop is placed.

The Caput Medusae acts as an ant plant in the wild, providing habitat to small animals. In return, the ants keep the plant safe by repelling pests and providing a natural fertilizer through their feces. When grown domestically, they enjoy the brightly lit spots that receive filtered bright light. This air plant loves humid air, so it prefers being sprayed instead of soaked in water.

A mature Caput Medusa’s grey-blue, snake-shaped leaves grow to a stature of around 9.8 inches. This air plant would look divinely located on a shell decoration or laid on a wooden saucer as centerpiece art.

#3. Circinata

The Tillandsia Circinata is a sturdy, light fuzzy green, stalky air plant with many characters. This air plant has trichomes covering the leaves, and they help the plant acquire nutrients from the air. During its blooming season, the crop grows strikingly bright yellow or purple flowers that attract bees and hummingbirds.

Tillandsia Circinata traces its original habitat in the countryside of Mexico, Costa Rica, the Bahamas, and the southern united states.

This air plant grows to an approximate width of 1 inch at the base and around 7 to 9 inches in height. The Circinata looks wonderful, mounted on driftwood.

#4. Juncea

This grass-like species is native to the west indies, Mexico and Central America. This Tilly looks fantastic in a hanging planter or a simple tabletop planter. It has a memorable fan-like leaf structure that grows to a height of about 12 to 18 inches. It is perhaps one of the biggest air plants found. Although, there are smaller versions of this crop that grow to a height of about 5 to 7 inches and 8 to 10 inches.

It is an extremely hardy plant that forms a clump over time, but before then, it blooms charming royal purple flowers. It does well under brightly filtered lights, a low- moderate watering regime, and an easy maintenance schedule.

#5. Xerographica

The xerographic air plant is striking, with a bright mossy green coloring on the gently gathered leaves. It is perhaps one of the most beautiful large air plants that look beautifully placed as it is. With or a container, it is a sight to behold. The leaves grow and curl inwards towards itself, forming a bowl-like shape. The leaves are thicker at the base and extend into thinner streams.

Tillandsia Xerographica relishes direct sunlight in the summertime. Its watering is not so time-consuming as one may either do a frequent misting or soak it in water for fifteen minutes at least once a month.

The seedling alone volumes 2 to 4 inches, and the jumbo matured one measures 8 to 10 inches. And with proper care, Tilly’s size can multiply three times over. The fascinating thing about this air plant is its bloom. Its sensational floweret can be an astounding four times the plant’s height. For this reason, the Xerographica makes an incredible centerpiece for any table.

When you think these air plants are growing too big, consider pruning them.

The Lifespan of Air Plants: How Long Do Air Plants Live?

The lifespan of air plants varies depending on the species and growing conditions. On average, air plants can live for several years (usually 2-5 years), with some species living up to 20 years. However, it’s important to note that the lifespan of air plants can be affected by various factors, including the environment, watering schedule, and overall care (as mentioned above). That’s why caring properly for an air plant is super important!

Here are a few examples I gathered during my self-conducted research:

How Fast Do Air Plants Grow?

Air plants generally produce new leaves and roots, but their overall size stays relatively consistent. Air plants are relatively slow-growing, and their growth rate can vary depending on the species and growing conditions. Some air plants can take several years to reach their full size, while others can grow more quickly. For examples:

Tillandsia xerographica~ 4-6 years to mature
Tillandsia ionantha~ 1-2 years to mature
Tillandsia brachycaulos~ 2-3 years to mature
Tillandsia caput-medusae~ 2-4 years to mature
Tillandsia tectorum~ 3-5 years to mature

* Please note that these are approximate numbers.

Final Words

Air plants can live for several years with proper care and growing conditions. While they are slow-growing plants, they can produce new leaves and roots over time and come in various sizes. By mimicking their natural environment, providing the right amount of water, and giving them regular care, you can help your air plants thrive and enjoy their stunning beauty for years.

Happy Planting!
