What are those flowers on the side of the road?
Short. Short flowering plants that grow along roadways include California poppy (Eschsholzia californica) and African daisies (Osteospermum). California poppy is the state flower of California.
Coreopsis : Florida's state wildflower
In 1991, the genus Coreopsis (Tickseed) was designated as Florida's Official State Wildflower in recognition of the colorful flowers used extensively in Florida's roadside plantings and highway beautification programs.
Chicory has a bright blue, 1 ½ inch wide flower and grows one to four-feet tall. Only a few flower heads open at a time and each last only a day. The roots are sometimes used as a coffee substitute or additive. I think the chicory flower shade of blue is one of the most beautiful in our plant world.
For our money, however, the two most common wildflowers (herbaceous native plants with showy flowers) are Blackeyed Susan (Rudbeckia hirta) and Common sunflower (Helianthus annuus). Both occur all across America and in many places occur in vast numbers.

Hemerocallis, or day lilies, have moved from their familiar roadside habitats to become the favorite flowers of the most discriminating gardeners. The ''Hems'' are now top-ranking perennials. The old ''lemon and orange lilies'' are still found along road banks and rural areas.
What is the name of the yellow flowers on the side of the road?
A couple common questions we get each spring are, "What's that yellow plant we see along so many highways, and why don't we do something about it?" The plant with the bright yellow flowers and distinctive smell is Scotch Broom, or Cytisus scoparious, an invasive species visible along many roadways this time of year.
What is the name of the pretty purple and white flowers blooming along the freeways and natural areas? They bloom in May and look kind of like a phlox. They are pretty and must be easy to grow - where can I buy them? These are Dame's rocket (Hesperis matronalis) a member of the mustard family and no relation to phlox.
