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.

Tansy

Tansy

Tanacetum vulgare

Tanacetum vulgare, commonly known as tansy, is a perennial herbaceous plant with a distinctive aromatic scent. It typically grows to a height of 0.5 to 1.5 meters. The plant features erect stems with fern-like, deeply divided leaves. It produces clusters of button-like, yellow flowers in late summer. Tansy is primarily an outdoor plant, valued for its insect-repelling properties and historical medicinal uses. It is not typically grown indoors due to its need for full sun and its potential toxicity. People grow it outdoors in gardens for its ornamental value and purported pest control benefits.

💡 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.

Tansy Care Tips

Tansy is primarily an outdoor plant and is difficult to grow indoors due to its high light requirements. It needs full sun and well-draining soil. It is also toxic to pets, requiring careful placement in gardens. Indoor cultivation is not recommended.

  • Plant in well-draining soil to prevent root rot.
  • Provide full sun for optimal growth and flowering.
  • Cut back after flowering to prevent self-seeding.
  • Monitor for pests and diseases regularly.
  • Avoid planting near areas where pets or children may ingest the plant.
❄️ Winter: In winter, tansy dies back to the ground. Cut back any remaining stems and apply a layer of mulch to protect the roots.
☀️ Summer: In summer, water regularly, especially during dry periods. Monitor for pests and diseases and treat as needed.

❓ 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.

Tansy

What are the light requirements for Tansy?

Tansy thrives in full sun, requiring at least 6 hours of direct sunlight each day to promote healthy growth and abundant blooms. An east- or south-facing window is ideal when growing indoors. Insufficient light can result in leggy growth, reduced flowering, and pale foliage. If natural light is limited, supplement with a grow light to provide the necessary intensity. Rotate the plant regularly to ensure even exposure to light on all sides. Avoid placing Tansy in excessively shaded areas, as this can weaken the plant and make it more susceptible to pests and diseases.

How do I care for Tansy?

Tansy requires well-draining soil and prefers a sunny location with at least 6 hours of direct sunlight per day. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain away. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune regularly to encourage bushier growth and remove spent flowers. Maintain moderate humidity levels. Provide adequate air circulation to prevent fungal diseases. Repot every 1-2 years as needed, using a slightly larger pot. Protect from frost in colder climates. Monitor for pests such as aphids and spider mites, and treat accordingly. Avoid overwatering, which can lead to root rot. Ensure good drainage to prevent waterlogged soil.

How do I propagate Tansy?

Tansy can be propagated through division, stem cuttings, or seeds. For division, carefully separate the root ball of a mature plant into smaller sections, ensuring each section has roots and foliage. Replant each section in a separate pot with well-draining soil. For stem cuttings, take a 4-6 inch cutting from a healthy stem, remove the lower leaves, and place the cutting in water or directly into moist soil. Keep the soil consistently moist until roots develop. Seeds can be sown directly into the garden in spring or started indoors 6-8 weeks before the last frost. Keep the soil moist and provide adequate light until germination. Transplant seedlings outdoors after the risk of frost has passed. Rooting hormone can be used to encourage quicker root development for stem cuttings.
