Lantana is a compact semi-evergreen tropical perennial often treated as an annual with toothed dark green foliage and large ball-like clusters of flowers that come in various colors or multicolored and bloom from spring until frost attracting butterflies.  Best color in full sun and rich well-drained soil.  Drought tolerant once established.  Toxic if ingested. 

This choice is a random selection of available colors that has been trained into tree form.  In areas without frost it can grow as tall as 6' feet.
