Pilea microphylla (py-LEE-uh my-kro-FIL-uh)

Family: Urticaceae Unknown Herbaceous (1-3 ft)

Artillery Plant is an herbaceous perennial that is grown in tropical Central and South America as a groundcover. In most parts of the United States, it is grown as a low-maintenance houseplant or as an annual in outdoor containers. It has a very delicate appearance, characterized by tiny lime-green leaves and fine stems. It has a creeping habit, forms a dense mat, and may grow 6 to 12 inches tall. The flowers are tiny and green, and it was aptly named the Artillery Plant because it forcefully ejects the pollen from its flowers. The Artillery Plant thrives in bright, indirect light. Direct sunlight can scorch its leaves. The plant is very sensitive to overwatering and underwatering. It prefers moist, well-drained potting mix and high humidity. Consider using a humidifier or setting the plant container on a tray of wet pebbles to increase the interior humidity. Propagation is best done by stem cuttings. This plant is very popular as a houseplant and is non-toxic to humans and pets. The Artillery Plant may be used in a terrarium. If you live in a very warm climate, consider this plant as a groundcover or filler in an outdoor container. Quick ID Hints: herbaceous perennial groundcover, clumping, spreading, dense habit, 6 to 12 inches tall, short, arching stems small, fine textured, lime green leaves that are fern-like tiny green flowers that ejects bursts of yellow pollen Insects, Diseases, and Other Plant Problems: Monitor for spider mites, mealybugs, scale, and aphids. Overwatering can result in root rot. In high humidity and poor air circulation, powdery mildew may occur.
