This field of Queen Palms, Syagrus romanzoffianna, (also known as Cocus Plumosa) have really grown this spring.   They have 6, 8 or 10 feet of clear trunk.  That means that the palms measure 12 - 16 feet tall overall.  

Above is the freshly dug rootball.  A queen palm doesn't need a very large rootball.  See the white dots?  Those are all roots that have been cut - the cut will cause them to branch 4" back and grow even more roots.   If the palms you purchase are not in containers, then fresh dug are best.  

Plant, stake, water, and enjoy!
