A weed is a plant that is unwanted or considered to be a nuisance. These plants are not intentionally planted and can be invasive. Some weeds may be flowering and appear to be a part of the planted garden. Weeds can prevent light from penetrating wanted plants and can choke out lawn grass.
There are over 50 different species of goldenrod flowers in North America. These plants are long and thin and can grow up to 6 feet tall. They have tiny yellow flowers that are clustered together on the ends of the slender stems. The pollen of the goldenrod is beneficial to many different insects. They can typically be found in pastures, along roadsides and open fields. The flowers bloom in late summer to early fall.
Dandelions are native to North America, Europe and Asia, but can be found all over the world. Dandelions reproduce by a parachute ball or a puff ball containing hundreds of seeds. The wind carries each seed away from the plant to another location where it will hopefully take root and grow a new plant. The dandelion flower is called a rosette. It is generally low to the ground and bright yellow to orange in color. Dandelions bloom from early spring to fall and can be difficult to control. They are one of the most common flowering weeds.
The wild sunflower is commonly found in fields and along ditches. Wild sunflowers contain many heads and many flowers, unlike the domesticated sunflower. They are yellow in color and bloom in late summer and early fall. The wild sunflower can be a problem in pastures, where it will take over grazing grasses.

Queen Anne's lace is also referred to as the wild carrot. The wildflower was brought over from Europe and is related to the domesticated carrot plant. The flower blooms from May to October and the stems can grow up to 3 feet tall. Queen Anne's flowers start as slightly pink until they open up an become bright white. As they grow they form a bowl shape which resembles a bird's nest. This flower can cause skin irritation, so care should be given when handling it.
