Zantedeschia aethiopica, commonly known as Calla Lily, is a rhizomatous herbaceous perennial prized for its elegant, trumpet-shaped spathes (modified leaves) that surround a central spadix. While often called a lily, it is not a true lily. It grows from rhizomes, producing large, arrow-shaped, glossy green leaves. It is primarily an outdoor plant, thriving in moist conditions. People grow it for its striking flowers, often used in bouquets and floral arrangements. It can be grown indoors, but requires specific conditions to thrive and may not flower as readily as outdoors.

Monkey Puzzle Tree

Araucaria araucana

The Monkey Puzzle Tree is an ancient evergreen conifer known for its distinctive, scale-like leaves and unusual branching pattern. It is a slow-growing, dioecious tree, meaning male and female cones are borne on separate plants. Native to the Andes, it can live for over 1,000 years. While highly prized as an ornamental tree for its unique appearance, it is primarily an outdoor plant and extremely challenging to grow indoors due to its size and specific environmental needs. People grow it for its striking architectural form and historical significance.

🔬 Botanical Information — Comparing These Plants

Calla

Scientific Name Zantedeschia aethiopica
Family Araceae
Native To South Africa
Also Known As Calla Lily, Arum Lily, Trumpet Lily
Leaves Large, arrow-shaped, glossy green leaves. The leaves can be up to 45 cm long and 25 cm wide. Some varieties have speckled or variegated leaves.
Flowers Can flower indoors with proper care, but more reliably flowers outdoors. The 'flower' is a modified leaf called a spathe, which is typically white, but can also be pink, yellow, orange, or purple. The spadix, the yellow spike in the center, is where the true flowers are located.

Monkey Puzzle Tree

Scientific Name Araucaria araucana
Family Araucariaceae
Native To Chile and Argentina (Andes Mountains)

❓ Frequently Asked Questions — Comparing These Plants

Calla

What are the light requirements for Calla?

Calla lilies thrive in bright, indirect light. Direct sunlight can scorch their leaves, so avoid placing them in south-facing windows without some form of shading. An east- or west-facing window is ideal, providing ample light without the intensity of direct sun. If you notice the leaves becoming pale or the plant failing to bloom, it may not be receiving enough light. In such cases, consider supplementing with artificial grow lights. During the darker winter months, supplemental lighting is particularly beneficial to maintain healthy growth and encourage future blooms. Ensure the light is diffused to prevent leaf burn. Regular rotation of the plant ensures all sides receive adequate light, preventing uneven growth.

How do I care for Calla?

Calla lilies require bright, indirect light for optimal growth and blooming. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. During the growing season (spring and summer), fertilize every 2-4 weeks with a balanced liquid fertilizer diluted to half strength to encourage flowering. Reduce watering and fertilization during the dormant period in fall and winter. Maintain a humidity level of 50-60%. Repot annually in spring using well-draining potting mix. Remove spent flowers to encourage more blooms. Monitor for pests like aphids and spider mites, and treat promptly if detected. Provide support for taller varieties to prevent them from bending. Rotate the plant regularly to ensure even growth and prevent leaning towards the light source. Protect from frost and freezing temperatures.

How do I propagate Calla?

Calla lilies can be propagated by division, stem cuttings (though less common), and keiki (small plantlets that sometimes form on the plant).

Monkey Puzzle Tree

What are the light requirements for Monkey Puzzle Tree?

Monkey Puzzle Trees thrive in bright, indirect light indoors. Avoid placing them in direct sunlight, especially during the hottest part of the day, as this can scorch their leaves. An east-facing window is often ideal, providing gentle morning light. A south- or west-facing window can work if you diffuse the light with a sheer curtain. Insufficient light can lead to weak growth and sparse foliage. Rotate the plant regularly to ensure even light exposure on all sides. Supplement with artificial grow lights if natural light is limited, especially during winter months.

How do I care for Monkey Puzzle Tree?

Monkey Puzzle Trees require bright, indirect light indoors. Direct sunlight can scorch their foliage. Water thoroughly when the top inch of soil feels dry, but avoid overwatering, as this can lead to root rot. Use well-draining potting mix. Maintain moderate humidity levels. Fertilize sparingly, only during the growing season (spring and summer) with a balanced, diluted liquid fertilizer. Repot only when necessary, as they prefer to be slightly root-bound. Prune only to remove dead or damaged branches. Provide stable temperature and humidity. Regular cleaning of the leaves will help with photosynthesis. Pot size should be adequate for root growth but not excessively large.

How do I propagate Monkey Puzzle Tree?

Propagating Monkey Puzzle Trees indoors is challenging but possible. Stem cuttings are difficult to root. Take stem cuttings in spring or early summer, ideally from the current year’s growth. Apply rooting hormone to the cut end and plant in a well-draining potting mix. Maintain high humidity by covering the cutting with a plastic bag or humidity dome. Air layering is another potential method. Make a shallow cut on a branch, wrap it with moist sphagnum moss, and cover with plastic wrap. Once roots develop, sever the branch below the moss and pot it up. Be patient, as rooting can take several months.
