I will say one thing that I really loved about this garden was ht away the husband and wife team used what Mother Nature had given them.
The beds were all outlined with coral rocks and the had been dug up or found. The paths were sea worn planks that had washed a shore during storms and hurricanes. The plants were intertwined with driftwood and in fact there were beautiful sculptures of drift wood through out the garden.
This was an amazing space that was full of exotic palms, orchids and much more. I will blog more about it later. But look around your area, there are gifts from nature all around us. Nothing makes a garden more unique than natural freebies.
