Pickleweed is an invasive or introduced plant in Hawaii. It has succulent, brilliant green leaves and is common in salt marshes and tidal shorelines. It grows slowly in soils with high salt concentrations and areas with seawater overwash where it suffers little competition from other plants. The species manages salts by sequestering them in cell vacuoles and eventually shedding the leaves

Front view illustration of a West Indian Lantana. It is a weed of cultivated land, fence lines, pastures, rangelands, and waste places. It thrives in dry and wet regions and often grows in valleys, mountain slopes, and coastal areas. It is somewhat shade-tolerant and, therefore, can become the dominant understory in open forests or in tropical tree crops. In pastures it forms dense thickets which shade out and encroach upon desirable pasture plants. With time it can form pure stands over large areas, the
