Confederate Jasmine is a vine which will grow on a fence or trellis. It blooms for several months in late Spring here in South Florida. Train it in an espalier shape or let it climb naturally. Requires very little water once established.
Brugmansia (Angel Trumpet)
Brugmansia also called Angel Trumpet, produces a huge flower that hangs upside down and blooms all day and all night. It smells like a cross between soap and perfume, especially at night. If you know someone who has a brugmansia, ask them to break off a 6-12" section, strip leaves, and plant in soil. In a few months, new growth will emerge and you'll have a free Angel Trumpet. Heavily cut it back often for a bushier plant. Here in South Florida, low temps will kill the plant, but it always comes back in a month or two. The flowers are poisonous to pets and humans if consumed.
The gardenia blooms from Sprint to summer. They are pretty susceptible to bugs, so they require maintenance. Other than that, the blooms are amazing. Make sure to get a grafted gardenia and to give it rooms to grow up in full sunlight.
Many Floridians love night blooming jasmine. It's got a very strong sweet aroma that fills the air in the night. The plant is easy to care for and requires pruning to make it bushy.
