Hollyhock
Hollyhocks are known for their tall spikes of trumpet-like flowers, commonly found in bright red, yellow, violet, white or pink. Hollyhocks can grow as tall as 8 feet, so have some stakes handy to prop them up and encourage growth.
Hyacinth
Hyacinths can be grown for for a variety of uses, such as outdoor containers, rock gardens or indoors
Lantana
Lantana blooms in combinations of red, orange, yellow, violet, white and pink. While popular for outdoor containers and houseplants, some have found the subtle citrus scent to be off putting.
Leadwort
Leadwort features dainty, dark blue flowers. While you may have to wait a while to see blooms, Leadworts are fine when left with morning sun and afternoon shade.
Lobelia
Lobelia is an excellent choice for hanging gardens or window boxes given their ability to create a long trail. Lobelias love intense heat and will bloom delicate flowers in shades of red, blue, violet and white.
