Bright, indirect light is best. Tolerates some morning direct sun (right in the window where sun actually hits the leaves. A strong grow light 4-6 inches away can substitute); protect from harsh afternoon sun. East or west-facing windows work well.Light

Water when the top inch of soil feels dry, roughly every 5-7 days. Keep soil consistently moist but never soggy - root rot is the main risk.Water

Enjoys high humidity (60-80%. Group your plants together, set them on a pebble tray with water, or run a humidifier nearby) but tolerates average household levels. Use a pebble tray or humidifier in dry conditions.Humidity

65-80°F (18-27°C). Avoid cold drafts and temperatures below 50°F.Temperature

Artillery Plant

Pilea microphylla

Easy

The Artillery Plant looks like an unassuming fern-like ground cover until you startle it — the male flowers literally explode pollen into the air in small visible clouds when touched or disturbed, which is where every one of its common names comes from. Your plant will stay compact at 6–18 inches tall and tends to trail nicely over the edges of a hanging basket or pot. It's non-toxic to pets and people, so that theatrical pollen launch is its most dangerous trait.

Did You Know

Fun Facts

The pollen-ejection mechanism is a real event you can trigger yourself: lightly tap the plant near the tiny male flowers and watch a small puff of pollen launch into the air — it's genuinely impressive for something so small.
