Peace Lily: Picture a peace lily. Its lush, dark green leaves fan out gracefully, creating a backdrop for its striking white flowers. Peace lilies prefer to keep their beauty confined indoors, thriving in warm, humid environments.

Calla lilies, unlike their peace-loving counterparts, often bask outdoors, adorning gardens with their presence.

Growing Medium

Peace Lily: Peace lilies thrive in a well-draining potting mix that retains moisture without becoming waterlogged. A mix of potting soil, perlite, and orchid bark provides the ideal growing medium, ensuring the plant’s roots stay healthy and happy.

Roots and Rhizomes

Additionally, feeding them with a balanced, water-soluble fertilizer every 2-3 weeks enhances their growth and encourages bountiful blooms.

The Difference Between Caring for Calla Lilies and Peace Lilies

Caring for these lilies boils down to understanding their unique needs. Peace lilies demand a humid environment, making them perfect bathroom companions. Regular misting or placing them near a humidifier ensures they remain content.

Calla lilies, on the other hand, thrive outdoors with their roots well-established in the ground. Adequate sunlight and proper watering are crucial. During winter, it’s advisable to dig up the rhizomes and store them indoors until spring, safeguarding them from frost.

Fake Lilies: Faux Lilies

In the quest for beauty, some resort to artificial alternatives. While faux lilies may seem like a convenient solution, they lack the natural charm and vitality of real plants. Moreover, they don’t contribute to the environment, missing out on the air-purifying qualities that living lilies, particularly peace lilies, bring to indoor spaces.
