A main attraction for bees and other pollinators, common yellow wildflowers are abundant in North America. They live in various habitats from desert scrub to California’s chaparral or from prairies to woodlands.
Multiple species of yellow wildflowers are introduced in North America. They complete the range of native wildflowers with yellow blooms.
Here are some of the most common species you can spot around North America and the world.
Table of Contents
1. Common Dandelion
Widespread distribution and uniform yellow flowers make The Common Dandelion (Taraxacum officinale) one of the most common yellow wildflowers.
Its flower heads are shaped similarly to balls and are seen around different fields in the summer.
Common Dandelion has a widespread distribution across Europe and North America.
Its rapid spread is also attributed to a high seed production rate. More than 100 seeds can be made by a single flower head.
2. Great Mullein
Great Mullein (Verbascum thapsus) is a species that blooms small yellow flowers. It represents one of the common invasive species across different fields, especially on disturbed land.
This species of plant is known for its invasive status. It invades disturbed lands as well as crops.

64. Fringed Loosestrife
Native to the Northern parts of North America, Fringed Loosestrife (Lysimachia ciliata) has large yellow flowers comprised of 5 petals.
The species has distinct nutritional value to bees. It produces plant oil and this attracts bees that aren’t necessarily interested in plant nectar.
Oligolectic ground-nesting bees feed on it. Macropis nuda is one of the oligolectic bees that only eats the oil of Fringed Loosestrife and which depends on the wildflower for survival.
