Plants That Have Yellow Flowers

Many varieties of plants bloom with yellow flowers. Some are just for show, some are good to eat and others may have medicinal value. Yellow flowers show up well against the green of most plant stems and leaves, announcing to the world that they are in full bloom.

Annuals

Annual flowers bloom one year. They must be planted again year after year for continued enjoyment.

 Sunflowers are annuals; they are usually tall and yellow, although some dwarf varieties with orange and red in the petals have been cultivated. They attract birds and add color to urban gardens.

Most sunflower varieties are planted directly in the ground in the early spring, after the last chance of frost has passed. Many varieties grow 6-feet or taller. They bloom in the late summer. As fall approaches, the heads swell so large that the top of the flower falls over, similar to a person with his head hung low. The head grows, the yellow petals fall off as the seeds grow larger, and the sunflowers attract many bird species to come feast on sunflower seeds.

Biennials

Biennial flowers complete their life cycle in two years instead of just one.

Black-Eyed Susans are easy to care for and very commonly grown outdoors in North America. While they prefer moist soil and full sun, they are extremely hearty and often survive if neglected. Most varieties are biennial, so when landscaping with black-eyed susans home owners must reseed every other year. The ease of care may make up for the work of reseeding.


Perrenials

Perennial flowers bloom year after year after year. They are a landscaper' dream because once the work of planting is done, the plants just need to be tended for the yellow blooms to come back every spring or summer. Fernleaf Yarrow is a perennial that prefers, like many yellow perennials, prefers full sun. Golden Columbine and Leopard's Bane, however, are yellow perennial flowers that do well in shadier or less sunny areas.

Edible Flowers

Zucchini and yellow crook-neck squash flowers are big and bright yellow before the fruit of the zucchini gets large. Some gardeners harvest the yellow flowers at full bloom and use them in recipes, then allow other flowers to die so the zucchini can grow. Zucchini flowers are a sweet and delicate, seasonal treat.
