Pilea trianthemoides

Pilea trianthemoides is a small, fine-leaved perennial related to the artillery plant (P. microphylla), native to Florida and the Caribbean islands, where it grows in waste places, moist thickets and rocky ground. It forms a dense, fern-like mound 10 to 15 cm tall (sometimes more), flowers year-round and is more drought-tolerant than P. microphylla. It is easy in a warm terrarium or on a bright windowsill but can self-seed aggressively.

Where it grows wild

A weedy plant of disturbed and open ground: waste places, moist thickets, and rocky limestone country such as the Los Haitises cockpit karst in the Dominican Republic. It establishes readily in pavement cracks, garden beds and pots, and has become invasive in some ornamental settings outside its range.

Most records are from lowland to low hill country. GBIF entries up to about 2,000 m (for example in Ecuador) and in northern Mexico are likely introductions or misidentifications.
