Oh dear - there are so many it could be - did these plants have flowers, or just foliage? What colour were the leaves and how far down did they trail? It could be Plectranthus argentatus or Ipomea batatas if leaves only, or Calibrachoa or Scaevola if it had little flowers. There are so many possibilities that without a description I'm only making wild guesses!

My wild guess would be lobelia! Give us a bit more to go on Steve! :)
