About
Pilea microphylla, also known as angeloweed, artillery plant, joypowder plant, lace plant, is an annual plant native to Florida, Mexico, the West Indies, and tropical Central and Southern America. In Guadeloupe and Martinique the local name is ti-teigne or teigne, and in Latin America it is brilhantina. In the southern part of México, specifically in the Yucatán peninsula, the local name is frescura. The plant belongs to the family Urticaceae. It has light green, almost succulent, stems and tiny leaves. It is grown as a ground cover in many areas.
How to grow it
Pilea microphylla can be propagated by dividing the root ball, or taking herbaceous cuttings and rooting them with rooting hormone. The plant enjoys a thorough watering after the soil has been allowed to dry, and misting has been shown to be beneficial. Direct sunlight causes the leaves to turn brown and fall off, so it prefers filtered light.
