Answer: By nature, bougainvilleas will sprawl if not supported on a trellis. If you're looking for a mounding, trailing shrub, any of the gold or orange colored bougainvilleas will fit the bill. You can prune bougainvilleas back to encourage a shrub-like appearance, or you can allow them to grow into a trailing, sprawling mound. It really depends upon the amount of space you can devote to your plant. California Gold, Gold Rush or Tahitian Gold are all plants that you might want to consider.
