Queen Anne's Lace (Daucus carota)
Several Hydrangeas (Hydrangea macrophylla)
Coral Honeysuckle (Lonicera sempervirens)
The last garden I visited was the largest on the tour, and it was the only one to have a lawn. However, the lawn was made of Mondo Grass (Ophiopogon japonicus) with the edges defined by taller, uncut Mondo surrounding a larger area of cut Mondo. In the center of the lawn was one of the most impressive Crape Myrtles (Lagerstroemia) I have ever seen.
Braided Oleander (Nerium oleander)
