Artillery Plant vs Moss Phlox Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
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.
Moss Phlox
Phlox subulata
Phlox subulata, commonly known as Moss Phlox, is a low-growing, mat-forming perennial. It is primarily grown as a ground cover in gardens and rockeries for its dense, cushion-like foliage and profusion of small, star-shaped flowers in spring. The plant forms a dense carpet of needle-like leaves, typically remaining evergreen in milder climates. It is not naturally an indoor plant and requires very specific conditions to thrive indoors, making it challenging to grow successfully inside. People grow it for its vibrant spring blooms and ability to suppress weeds.

💡 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.
Moss Phlox Care Tips
Moss Phlox is primarily an outdoor plant. Growing it indoors is extremely challenging due to its high light requirements and need for well-drained soil. It requires full sun and careful watering to prevent root rot. Indoor success is unlikely without supplemental lighting and precise environmental control.
- Ensure excellent drainage to prevent root rot.
- Provide full sun for optimal flowering.
- Shear lightly after flowering to maintain shape.
- Apply a slow-release fertilizer in early spring.
- Water deeply but infrequently, allowing the soil to dry out between waterings.

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.
Moss Phlox
What are the light requirements for Moss Phlox?
Moss Phlox requires at least six hours of direct sunlight each day to thrive and produce abundant blooms. A south-facing location is ideal, but east or west-facing spots can also work if they receive sufficient sunlight. Insufficient light can lead to leggy growth, reduced flowering, and increased susceptibility to diseases.
How do I care for Moss Phlox?
Moss Phlox thrives in full sun and well-drained soil. Water regularly after planting and during dry spells, but avoid overwatering. Fertilize in early spring with a balanced fertilizer to promote flowering. Prune lightly after blooming to maintain shape and encourage denser growth.
