Favorite Plants 

Salvias are an all-time favorite because this large genus is full of tough plants that are big performers. Many perennial types will bloom all summer long and can stand up to heat and humidity without sacrificing on appearance. On top of it, salvias support many types of pollinators. Ornamental grasses are another underused group. They add movement and soften hard edges in a landscape.

I plant them en masse to provide a cohesive texture throughout my plantings. Japanese maples are also a favorite because of their vibrant fall colors and beautiful form. Learning to correctly prune Japanese maples is a lifelong endeavor and has been a fun skill to practice.
