What Is a Bromeliad Cup

Most bromeliads have a cup-like structure at the center of their leaves. This cup also called a tank, is where the plant stores water. It helps the plant to stay hydrated and also provides a place for insects and other small animals to live.

It is an important part of the plant’s life cycle. Without the cup, the plant would not be able to absorb the nutrients it needs to grow and reproduce.

In this blog post, we will discuss what a bromeliad cup is, how it helps the plant, and some of the different types of bromeliads that have this special feature, and more interesting facts about this amazing plant! So, let’s start!

What Are Bromeliad Cups Used for?

Bromeliad cups are an essential part of the plant’s anatomy and play a vital role in its survival. Understanding the different functions of the cup can help you better care for your bromeliad and keep it healthy. Here are some of the things bromeliad cups are used for:

Water Reservoir

These plant cups can hold a significant amount of water, which is essential for the plant’s survival. The plant draws moisture from the cup to help it stay hydrated during periods of drought.

Shelter for Small Animal

Bromeliad cups provide the perfect shelter for small animals like frogs, lizards, and insects. The cup offers protection from the elements and predators. The plant also benefits from the animal’s presence, as they help to pollinate the flowers and spread the plant’s seeds.

Debris, like stray petals and leaves, can be gathered in bromeliad cups as well. For the plant to remain healthy, this debris can supply nutrients.

Act As a Humidifier

It can help increase the humidity around your plants, which is especially beneficial if you live in a dry climate. By filling the cups with water, you can create a mini humidifier that will help your plants stay healthy and thrive.

How to Care for Bromeliad Cups?

Just like other plants, bromeliads need the right amount of water, light, and nutrients to thrive. But these plants have a unique feature that sets them apart from other houseplants: their cups.

Bromeliad cups are the leaves that form a cup-like shape at the center of the plant. These cups collect water and nutrients, which the plant then uses to grow.

Because of this, it’s essential to care for bromeliad cups properly. Here are a few tips on how to do so:


The most important thing to remember when watering bromeliads is to not let the cups dry out. These plants rely on their cups to collect water, so if the cups are dry, the plant will suffer.

The best way to water bromeliads is to use a spray bottle like dew and mist the plant, making sure to get the water into the cups. You can also dunk the plant in a sink or bucket of water, letting it soak for a few minutes before draining.


Bright, filtered light is essential for bromeliad growth. It is ideal to arrange the leaves somewhere where they will receive plenty of light without being in direct sunshine because too much direct sunlight might scorch the leaves.

If you live in a particularly sunny climate, you may need to place your bromeliad in a spot that gets some shade during the day.


These plants need nutrients to grow, but because they collect water and nutrients in their cups, they don’t need as much as other plants.

An excellent way to provide nutrients for your bromeliad is to add a small amount of fertilizer to the water every few weeks. Just be sure to use a fertilizer that’s specifically designed for bromeliads, as using the wrong type of fertilizer can harm the plant.

With proper care, bromeliads can thrive for years. By following these simple tips, you can ensure your bromeliad stays healthy and happy.

What Are the Different Types of Bromeliad Cups?

These cups are typically found in the axils of leaves and come in a variety of shapes and sizes. The most common type of bromeliad cup is vase-shaped, which is found in the vast majority of bromeliad species.

Other common bromeliad cups include bowl-shaped, urn-shaped, and truncate cups. Each of these types has its own unique characteristics that help to distinguish it from the others.

Vase-Shaped Cup

The most prevalent variety of bromeliad cup is vase-shaped, and it may be seen on several well-known species, including Aechmea fasciata. It has a vase-like shape with a broad top opening and a smaller base. Water collects in the cup, and the plant uses this water to help it survive in dry conditions.

Urn-Shaped Cup

This type of bromeliad cup is found on plants like the Vriesea bromeliad and has a wide, flared shape. The urn-shaped cup is adapted to hold more water than other cup shapes, making it ideal for use in dry climates.

Bowl-Shaped Cup

The most common type of bromeliad cup is bowl-shaped, with the edges curving inward to form a sort of basin. This type of cup is great for trapping water and debris, making it ideal for bromeliads that live in humid environments.

Truncate Cup

This is characterized by its truncated (i.e. flat) bottom. The truncate cup plants are well-suited to growing in a wide range of substrates, including potting mix, sphagnum moss, and even bark.

Final Say

In conclusion, bromeliad cup is a tank of water that stores in the center of the plant and provides nutrients and moisture to the plant. There are many different types of bromeliad cups, but they all serve the same purpose.
