I have a business ( tanning beds ) that is wanting to install some flowerbeds and wanting them to look tropical. I have thought of some 2 or 3 ft palm trees and also some ferns. I am trying to come up with some other ideas and needing some input on this.. what other plants would you use and what type of ground cover would you use.. I have looked on the web alittle and have not found anything that caught my eye.. I thought some or you guys could help and possibly supply some pics on this.. the flower bed is going to be around 30ft long and 5 to 6ft deep.. any help would be GREATFUL.. thanks!!
