*Boxwood 'Dee Runk' is reportedly the nicest of the columnar boxwoods tolerating shade and clay soils. Total height of 8-10 ft tall can be sheared shorter. Max width about two feet. Advantage over other upright boxwoods is dense growth that won't flop open. Will fit nicely next to the porch stairs and in the corner by the garage.
Catnip is said to be 10 times more effective than DEET in repelling mosquitoes. Citronella, or West Indian lemongrass, is a tall plant and the source for citronella oil. Cascading Geranium, another bug repelling plant, will cascade over its pot and add a delicate floral scent to your potagerie.
