The condition or the time of year that a plant develops leaves or sprouts is called frondescence. This noun stems from the Latin word frondescentia meaning to “become leafy.” According to the Oxford English Dictionary, the word was first recorded in the English language in 1793 by Thomas Martyn who described in The language of botany, that frondescentia is the “leafing season..the time of the year when plants first unfold their leaves.”
Typically, plants grow very slowly so that if you watch the growth of a new shoot in real time, you wouldn’t be able to see the progression. Time lapse video, in which the speed of the video frames has been increased, lets viewers experience the new vegetation growth. This 40-second time lapse video by Erik Solheim shows the progression of a frondescence as the trees move through the seasons. Starting at winter, the tree branches are bare and covered in a light dusting of snow. As the snow melts and the ground warms up, the spring seasons welcomes in new vegetation. The frondescence is in full swing as the trees grow new foliage and the ground becomes carpeted with grasses and other plants. Solheim describes in detail on his site how he created his foliage video.
