Artillery Plant

Pilea microphylla

The Artillery Plant (Pilea microphylla) is a fast-growing, bushy plant known for its unique method of pollen dispersal. It's characterized by its tiny, bright green leaves that densely cover its delicate stems, giving it a fern-like appearance. The plant gets its name from its ability to explosively eject pollen into the air when disturbed, resembling tiny bursts of artillery fire. While it can be grown indoors, it thrives in humid, warm conditions, often performing better in greenhouses or terrariums. People grow it for its interesting foliage and unusual pollen-shooting behavior.

Canna Lily

Canna indica

Canna indica, commonly known as Canna lily, is a rhizomatous perennial with large, paddle-shaped leaves and showy flowers. It's primarily grown outdoors for its tropical appearance and vibrant blooms, which come in various colors like red, orange, yellow, and pink. The plant grows from rhizomes, spreading readily in suitable conditions. While it can be grown indoors, it requires very bright light and ample space to thrive, making it more challenging than typical houseplants. People grow them for their bold foliage and exotic-looking flowers.

🔬 Botanical Information — Comparing These Plants

Artillery Plant

Scientific Name Pilea microphylla
Family Urticaceae
Native To Tropical Americas and West Indies
Also Known As Artillery Plant, Rockweed, Gunpowder Plant
Leaves The leaves of Pilea microphylla are tiny, measuring only a few millimeters in length. They are bright green in color and have a delicate, almost translucent appearance. The leaves are oval-shaped and have a smooth texture. They are densely packed along the stems, giving the plant a lush and full look.
Flowers The artillery plant produces tiny, inconspicuous flowers that are rarely seen indoors. The plant is primarily grown for its foliage rather than its flowers. The flowers are responsible for the plant's unique pollen dispersal mechanism.

Canna Lily

Scientific Name Canna indica
Family Cannaceae
Native To South America
Also Known As Canna lily, Indian shot, Achira, Queensland arrowroot
Leaves Large, paddle-shaped leaves, typically 30-60 cm long and 10-20 cm wide. The leaves are usually green, but some cultivars have bronze or variegated foliage. The texture is smooth and slightly waxy.
Flowers Canna lilies rarely flower indoors due to insufficient light. Outdoors, they produce showy, asymmetrical flowers in shades of red, orange, yellow, pink, or bi-color combinations. The flowers are borne on tall stalks above the foliage.

💡 Pro Tips For Comparing These Plants

Artillery Plant Care Tips

Artillery plants require bright, indirect light, high humidity, and consistent moisture. They can be prone to pests and diseases if not properly cared for. Regular pruning helps maintain a compact shape. While relatively easy, maintaining humidity is key for indoor success.

  • Maintain high humidity by misting regularly or using a humidifier.
  • Water thoroughly when the top inch of soil is dry, but avoid overwatering.
  • Provide bright, indirect light to prevent leaf scorch.
  • Pinch back stems regularly to encourage bushier growth.
  • Inspect regularly for pests and treat promptly.
❄️ Winter: Reduce watering frequency during the winter months as the plant's growth slows down. Maintain humidity levels, as indoor heating can dry out the air. Provide adequate light, especially during shorter days, by using a grow light if necessary.
☀️ Summer: Water more frequently during the summer months as the plant's growth increases. Protect the plant from direct sunlight, which can scorch the leaves. Ensure good air circulation to prevent fungal diseases. Fertilize regularly during the growing season.

Canna Lily Care Tips

Canna lilies are primarily outdoor plants that require full sun and ample moisture. Growing them indoors is challenging due to their high light requirements and potential for aggressive rhizome spread. They need large pots and frequent fertilization to thrive indoors. Expect less flowering indoors.

  • Provide ample sunlight – at least 6 hours of direct sun is crucial for flowering.
  • Water deeply and regularly during the growing season, but avoid soggy soil.
  • Fertilize every 2-4 weeks with a balanced liquid fertilizer to promote healthy growth and flowering.
  • Protect from strong winds, which can damage the large leaves.
  • Overwinter rhizomes indoors in colder climates by storing them in a cool, dry place.
❄️ Winter: In colder climates, Canna lilies are not winter hardy. After the first frost, cut back the foliage and dig up the rhizomes. Store them in a cool, dry place (around 4-10°C) in peat moss or vermiculite until spring.
☀️ Summer: Provide ample water and fertilizer during the growing season. Protect from strong winds. Deadhead spent flowers to encourage continued blooming. Monitor for pests and diseases.

❓ Frequently Asked Questions — Comparing These Plants

Artillery Plant

What are the light requirements for Artillery Plant?

Artillery Plant prefers bright, indirect light. Avoid direct sunlight, especially during the hottest part of the day, as it can scorch the delicate leaves. An east-facing window is often ideal, providing gentle morning sun. A north-facing window can also work, but the plant may not grow as vigorously.

How do I care for Artillery Plant?

Artillery Plant thrives in bright, indirect light; direct sunlight can scorch the leaves. Water regularly, keeping the soil consistently moist but not soggy. Allow the top inch of soil to dry out slightly between waterings. High humidity is beneficial; mist the plant regularly or place it on a pebble tray.

How do I propagate Artillery Plant?

Artillery Plant is easily propagated through several methods. Stem cuttings are a simple and effective way to create new plants. Take a 2-3 inch cutting from a healthy stem, remove the lower leaves, and place it in water or directly into moist potting mix. Roots will typically develop within a few weeks.

Canna Lily

What are the light requirements for Canna Lily?

Canna Lilies need at least 6 hours of direct sunlight daily to thrive and produce abundant blooms. Insufficient light can lead to leggy growth and reduced flowering. Place outdoor Cannas in a location that receives full sun throughout the day.

How do I care for Canna Lily?

Canna Lilies thrive in full sun and well-draining soil. Water deeply when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Fertilize regularly during the growing season with a balanced fertilizer, switching to a bloom-boosting formula as flowering begins.

How do I propagate Canna Lily?

Canna Lilies are easily propagated by rhizome division. In early spring, carefully dig up the rhizomes and divide them into sections, ensuring each section has at least one growth eye. Plant the divisions in well-draining soil, about 4-6 inches deep. Water thoroughly and keep the soil consistently moist until new growth appears.
