What is a Flower Bud?

Mary McMahon

A flower bud is an immature flower which is usually covered in protective scales which shelter it while it develops. As the flower matures, the bud opens, allowing the flower to emerge. This can take hours or days, depending on the climate and the plant. Once fully matured, a flower may also curl up during various times of the day or night for the purpose of protecting itself from harsh conditions. The flower bud is often used in metaphors which are designed to imply potential, because every flower bud has the potential of developing into something beautiful.

If a flower bud does have scales, these scales are actually modified leaves. Depending on the plant, they may enlarge and open with the bud, or they may shrivel and drop away. Some flower buds are covered in a gummy material which offers additional protection while the flower matures, deterring insects which might attempt to set up camp inside the sheltered area of the bud. This sticky material can also cause flower buds to adhere to passing animals, which is one of the many reasons plants tend to produce multiple flowers, ensuring that at least some of them make it all the way to maturity and fertilization.

Other flower buds may be hairy, sometimes retaining the hairy scales as the flowers mature. Some plants may have naked buds which are fully exposed during development. It is not uncommon for flower, leaf, and stem buds to look remarkably similar until they have developed and matured, because plants often employ the same protective techniques for all new growth which is in the process of budding.

Depending on the plant, a flower bud may develop into a single flower or a group of flowers. As many gardeners have noted, if a branch with buds is severed and is well cared for, the buds may mature and unfurl on their own. This is sometimes used by companies which supply cut flowers, with the company cutting the flowers as buds so that they can be transported without damage, and then promoting maturation once the flowers reach their destinations.

Not all flower buds mature. Sometimes a bud becomes diseased, in which case it may fail to open. Infestation with parasites, insects, worms, and other organisms can also delay maturation. Sometimes, an entire tree or plant becomes diseased and none of the buds open, in which case the plant will not produce flowers or fruit.

@JessiC – It sure sounds like you’ve got a heck of a disease going around your yard! It could be that or it could be drought causing your flowers to brown and die before blooming.

It's so disgusting for your buds to die before you ever even get near a flower vase!

Are you in a dry climate, or has your area lacked a lot of rain? I would try some good old love and care for your flowers first to see if that worked - lots of water and fertilizer.

If that doesn’t help, then you might want to go to your local nursery with a sample of the disease ridden buds. They will probably have a very good idea of what your problem is. More importantly, they will probably have a solution!


One of the most beautiful flower arrangements I ever got was nothing but flower buds when it first arrived at my door.

It came from one of those online flower delivery services where you’re supposed to get the freshest flowers in the shortest amount of time.

My husband had heard me say something about them and how I would love to see if they were legit, so he ordered me a wildflower mix in a bud vase.

Wow! Although it was a little odd to get flowers that were not fully open and ready for display, they were still quite beautiful. And once they did open up they were amazing.

I also liked it because they lasted longer than other live arrangements I’ve gotten in the past.


Earlier during the growing season, I was so excited that my Camilla was just covered in the most beautiful white flower buds. I mean, this gorgeous bush was just hanging with them.

I kept waiting and waiting and waiting for them to bloom, and was so sorry to see that they turned brown and died before ever maturing.

I suppose some sort of disease must have taken them, and since I’ve had both rose flowers and Ivy leaves get these ugly brown spots, I'm guessing they've got the same thing. The roses quite bearing after this happened as well.

Does anyone know what might have happened to my flower buds?
