Similarities and Difference of Peace Lily vs Calla Lily

Peace lily and calla lily are both adored for their lush foliage and delicate-looking flowers. They are both members of the Araceae family and have features that are similar to true lilies.

Many tend to confuse calla lily and peace lilies, but they have some prominent differences. Let’s look at a few things that will help you set apart peace lilies from the calla lilies.

The Size

The most prominent difference between a peace lily and a calla lily is the size of the plant. The outdoor varieties of peace lily grow to about 6 feet high and 5 feet wide. While the indoor ones just reach the height of fifteen or sixteen inches.

Calla lily isn’t as big as the peace lily, the biggest ones growing to around 3 feet high and 3 feet wide. They need quite a lot of space to grow, but not as much as the peace lily would need.

The Foliage

Both these plants differ from each other in terms of their leaves and foliage as well. Peace lily leaves are shaped like ovals and are broad, dark green, and glossy. Some varieties of peace lily have variegated leaves, while some have plain leaves and others are ribbed.

On the other hand, calla lily has paler leaves with pointed tips and are shaped like arrowheads. They are thinner and less dramatic as compared to the leaves of peace lily.

Light Requirements

Peace lilies prefer a lot of light but cannot cope well with full sun. When growing them indoors, remember to place them in a location a few feet away from the window and away from direct sunlight. It is good to grow peace lilies under another plant having a light canopy so that the peace lily receives just enough light to carry out effective photosynthesis.

Calla lilies on the other hand grow better under full sun, or in partial sunlight. They can even grow well in shady areas, without having enough light, but calla lilies prefer good sunlight. However, it is important to note that too much sunlight during the peak summer days can burn the leaves, so placing them in the shade for a while when the sun is at its strongest would be a good idea.

Rhizomes and Roots

Peace lily and calla lily may seem similar above the ground but are very different undergrounds. A peace lily has a ball of tangled roots that gathers nutrients and moisture for the plant whereas calla lily grows from rhizomes, which are blobby, bulbous and pale brown in color. These absorb moisture and nutrients for the calla lily to grow.

The Growing Medium

The peace lilies may like wet conditions but are to be dried out from time to time. Make sure that you have good drainage material when planting a peace lily so that the roots do not rot due to moisture.

Similarly, calla lilies like wet conditions to grow, and you can even grow them directly in water. Water them regularly and don’t dry them out, even if they seem wet. Don’t grow the plants in poor conditions, but rather in nice and rich soil.

The Flowers

The flowers of peace lily and calla lily are quite different. White flowers bloom on a peace lily plant that has a yellow spike in the center. Calla lily on the other hand can bloom flowers of many different colors, ranging from yellow, pale pink, cream, red, and purple.

An important thing to note about the flowers is the time they bloom. Calla lily flowers bloom just in summer in warm weather with a lot of light while peace lily can even bloom in the middle of the winter if you use a grow lamp.

Take – Away

When it comes to peace lily vs calla lily, the most interesting fact is that they are both named ‘lily’ but belong to the Araceae family and are not regular lilies. Both varieties of lilies can thrive as houseplants or outdoors and are very popular for their lush foliage and beautiful and delicate flowers.

Peace lily and calla lily can be easily differentiated on prominent features, such as their leaves, their size, the amount of light they need for growth, and their foliage and flowers. Despite the similarities and differences, both the peace lily and the calla lily make wonderful plants to add character to your indoor and outdoor living spaces.
