Perennial Herbs

Plant in the back is  Citronella

CITRONELLA
The true citronella plant is a perennial grass similar to Lemon Grass, to which it is closely related. It is not the little scented geranium you find in some stores labeled as a "mosquito plant." Those may smell like citronella but are about as close to citronella as the lime-scented geranium is to a lime tree. Citronella is a clumping grass that grows five to six feet tall. The coarse, grasslike leaves are gray-green and aromatic and are borne on cane-like stem
Growing citronella....
Citronella is generally purchased as a small plant. Make sure you are getting true citronella, Cybopogon nardus or Citronella winterianus
Citronella is undemanding in its care. It should be grown in full sun and watered when it gets dry. It does not like to be too wet,
You could plant citronella in areas where you sit to repel insects, or scatter leaves from the plant around you. From  my own experience this plant on my deck helped quite a bit in the control mosquitoes.
