Goldenrods (Asteraceae: Solidago
spp.) are an familiar sight of the Eastern Deciduous Forest in the late
summer and fall. Solidago is a very large genus. The species on
the left is Early Goldenrod, Solidago juncea, a common species
of roadsides, rocky banks, and open woods. Goldenrods are usually associated
with old fields or roadsides, but species occur in a vast variety of habitats
from old fields to deep forests to swamps and marshes. Goldenrods can
almost always be identified by the clumped, linear groups of small yellow
flowers.
The concept of an individual is very nebulous in goldenrods. Sometimes
if you look out over a field of goldenrods and see hundreds of "individuals",
you are actually looking at a single individual with hundreds of stems
all connected underground by their root system. |

Asters (Asteraceae: Aster spp.) are
another large genus of composites. This particular species is New England
Aster (Aster novvae-angliae). The genus Aster has a large
number of species in North America and is very diverse in the Eastern Deciduous
Forest. Although New England Aster is purple, other species are pink, white,
and all shades in between. Asters can be found in just about every type
of habitat in eastern North America from old fields to deep woods. Most
species, however, and found in forest openings or meadows or their man-made
equivalents, old fields and roadsides. |
