There are two plants that really dress up a Houston garden: Lantana and Esperanza. My Lantana are not doing well due to excessive rain that destroyed their flowers and saturated the ground and their roots shortly after they were planted. The Esperanza plants are doing very well, having been established for more than two years, surviving all the drought, the freezes, and the super saturation of recent rains.
Above: Lantana - with their flower heads of multiple tiny flowers. Mine have grown skinny and flowerless but I am hopeful they will make a comeback with the right growing conditions.
Above: Esperanza - a delicate trumpet flower with a beautiful buttery color. The name is inspiring: Hope. These plants often have to be staked because they will droop over, their tender stalks unable to cope with the weight of all the shoots.
