Two sites are always allotted for the show, one for the landscape design and exhibit, where prizes are given. The other site is occupied by the commercial booths, where fruit trees to cactuses are available for sale. My office is just a short distance ride from the area, so i can always pop-in when i feel like it.
The big heart design is easily accomplished with the more common flowering plants: marigolds, torenia, impatiens, etc.
The big acacia tree, Samanea saman, provided a beautiful backdrop for back to back exhibit. This side is composed of the aroids and ferns, while at the back of this shot, facing the entrance are mostly decorated with hoyas. The left side is planted with agaves, orchids and philodendrons and other filling plants. Even the high branches are laden with cascading plants, making it like a natural setting.
The above basket holds a lot of epiphytes but mostly hoya, hanging on a very high tree branch.
