Jefferson was a horticulturist and a scientist. He had an insatiable curiosity about the natural world. He laid out gardens and orchards as well as four circuitous roads called called "roundabouts." The gardens were a living laboratory for the study of plants from around the world. He chronicled all the details of his work as well.
A Daisy flower is composed of white petals and yellow centers, although the flowers are sometimes a pink or rose color. Stems of Daisies are smooth and leafless and support a single flower. Daisies are not one flower. A Daisy is made up of two types of flowers - disk florets and petal-like white ray florets.
The Disk florets are at the center and the ray florets are at the periphery. But these are arranged to give the impression of being a single flower. This arrangement on Daisies is a type of inflorescence known as a capitulum.
