Types of Weeds and Flowers

The vast array of weed and flowers varieties is incredibly expansive. While flowers are generally planted in the garden to add color, interest and sometimes fragrance, weeds are most often considered an unwanted, invasive plant. Weeds may cohabitate with ornamental flowers, but they often compete with flowers or act as hosts for insect infestations, leading to diminished vigor of flowers.


Dandelions (Taraxacum officinale) are one of the most recognizable perennial weeds, according to the Clemson University Extension. With green foliage and yellow flowers that bloom during spring, dandelion weeds usually thrive in areas exposed to full sun; these weeds grow in nearly any soil type. Dandelions reproduce by seed. For control of this weed, hand pull them from the soil with the assistance of a gardening tool. For control near ornamental flowers, mulch the soil surrounding the flowers with up to 3 inches of organic material like compost or pine needles to prevent the growth of weeds. Additionally, if dandelions become a severe problem, apply an herbicide formulated for dandelion control. Remember that chemicals may hurt nearby plants and animal life.

Japanese Clover

Japanese clover (Kummerowia striata), also referred to as common lespedeza, is a low-growing annual weed that remains near the ground. Japanese clover is wirelike in texture and displays green leaflets with a prominent, central vein. This weed displays flowers in purple to pink hues during summer, according to the Clemson University Extension. Reproducing by seed, this weed is easily pulled from the ground by hand for removal. As with dandelions, apply mulch to ornamental flower beds as a preventive measure and use an appropriate herbicide for severe infestations.

Colorado Columbines

Colorado columbines (Aquilegia coerulea James), also referred to as Colorado blue columbines, Rocky Mountain columbines and blue columbines, are perennial flowers. This erect plant displays flowers in solid or bi-colors of pink, blue and/or white, according to the Utah State University Cooperative Extension. Thriving in light to moderate shade, Colorado columbines should be planted in moist soil rich in nutrients; though tolerant to many types of soil, avoid poor drainage. With a bloom time of April through July, these flowers grow to a height of 1 to 2 feet and attract hummingbirds into the garden.

Fringed Leaf Bleeding Heart

Fringed leaf bleeding hearts (Dicentra formosa) are perennial flowers. Displaying small flowers in white, pink and red, blossoms resemble a heart in the process of bleeding, as the name suggests, as though a drop of blood is falling underneath. Thriving in partial sun to full shade, these flowers prefer moist, well-drained soil, according to the University of Illinois Extension. Bloom months are May through August. Fringed leaf bleeding hearts attract hummingbirds and grow to a height of 15 to 18 inches.
