ABOUT THE GUIDE
The goal of this guide is to help identify native plants at various stages of growth.
Color photos illustrate seed, seedling,
juvenile, and flowering stages, in addition
to a distinguishing characteristic. Brief text
provides additional identification help.
Images of the seedling stage depict the
appearance of a single cotyledon (first leaf)
in grasses and a pair of cotyledons in broad-
leaved plants, followed by photos of the first
true leaves within three weeks of growth in
a controlled environment.
Images of the juvenile stage portray the
continued development of a seedling with more
fully formed leaves within the first eight weeks
of shoot development .
Images of the distinguishing characteristics show a
specific biological feature representative of the plant.
Please note that seed images do not represent the actual size
of the seed. The scale is in 1/16-inch increments.
