Dahlias are beautiful ornamental plants grown for their striking flowers. They bloom from midsummer to fall and come in a variety of colors and sizes, making them great additions to your garden. One of the best things about dahlias is that they grow well in most climates and soil types, so there’s no need to worry about where you live.

The cost of dahlias depends on where you get them from, but they range anywhere between $5-$10 per stem or bulb. Prices may vary depending on size and color as well as shipping costs if applicable (some retailers charge extra).

If you’ve ever been curious about how to buy dahlias, you’ll be happy to learn that you’re not alone. This article will cover the color and size, as well as their care and price. Here are some tips to help you make a wise decision:


Dahlias vary in size, from a pinky-size tuber to a 10 inch giant. Their height varies as well. Dahlias may produce up to twenty flowers, and they can grow eight feet tall. They are best started indoors, which will result in a larger plant. Here are some tips for growing dahlias. To increase flower production, plant dahlias in a sunny location.

Dahlias are divided into four groups, or sizes, based on their flowers. The largest Dahlias are the Dinner Plate and the Semi-Dinner Plate. These varieties are tall and have symmetrical blooms. They bloom continuously until frost. However, there is no official classification for Dinner Plate Dahlias, and their blooms can vary widely. The information in this article has been written based on several outside sources.

The smallest dahlias are two to three inches in diameter. In contrast, the large dahlias can reach four to five feet. The biggest dahlias are the dinnerplate variety, which has double flowers and grows in the back of perennial borders. However, dinnerplate dahlias need support in the summer months and may require whimsical spiral supports. So, the next time you decide to plant them in your garden, make sure to research their sizes and how big they can grow.

The size of your tuber also affects the number of flowers produced by a dahlia plant. While they are generally smaller than their cousins, larger tubers can produce as many as twenty flowers. Larger tubers are also preferred for outdoor planting because they will produce more flowers. However, if you are growing a Dahlia for flower production, you may want to consider a larger tuber.

A dahlia should be staked or tied to a stake after they’ve grown about a foot tall. It’s important to pinch the stem at the base of the plant to encourage strong side-branching. If the dahlia is smaller, one pinching is sufficient. In addition, dahlias should be tied to a stake during planting time. Loosely tie the stake to the ground before the third leaf set.


Dahlias are a hardy, multi-petaled flower with a layered name. The word dahlia is a genus name and actually means many different things. It is believed that Carl Linnaeus named it after his student who had the last name Dahl. Dahlias also symbolize grace under pressure and inner strength. They are also a symbol of commitment to an idea or person. Dahlias also represent a balance between relaxation and adventure.

A typical dahlia has a single color, but it can be striped or have different colored edges. Petals may be rounded or pointed, and may be curled or straight at the edge. Dahlia flowers can be five to thirty centimeters in diameter. Some varieties are a blend of several colors. Dahlias also come in dwarf forms, which don’t grow much taller than 24 inches.

The red-purple variety has a large concentration of anthocyanins, a group of plant metabolites that give red-purple flowers their colour. The anthocyanins in red dahlias are the same pigments that make blueberries, blackberries and blue corn red. White dahlias lack anthocyanins, but have large amounts of flavones, which alter the shade of anthocyanins in a flower.

The Dahlia genus has more varieties than any other flower genus. Dahlias are not only versatile but also structurally diverse. They come in white, shades of pink, red, yellow, orange, and purple, as well as many combinations of these colors. While you can purchase a dahlia tuber from a local garden center or online, the color of dahlias can vary wildly.

If you are not able to grow the variety you are looking for, you can purchase tubers and replant them in the spring. Dahlia tubers are easy to store and replant. Once they are established in the garden, you can enjoy their beautiful blooms year after year. If you are growing Dahlias for display, you’ll have to know which cultivars to choose. The Snohomish Dahlia Society has their national show scheduled for next year. In the meantime, the Portland Dahlia Society is planning its next national show.


While dahlias can tolerate deer, they will usually stay away if you provide them with other food sources. There are a few pests that can cause damage to dahlias, the most common being aphids, thrips, and Japanese beetles. Fungus diseases are also possible, but you can prevent these by keeping the foliage clean and dry.

Tubers should be carefully dug out before winter. Dig up the tubers from the soil by one foot away from the stem and place them in a cool, frost-free area. Remove any mold from the tubers with a toothbrush or paintbrush. To remove infected tubers from the flower bed, cut away about 3/4 of the tuber. If the plant is still growing well after the cut, do not worry.

Before planting your dahlias, make sure the soil is well-drained and sandy. They require regular watering. To determine how fertile the soil is, perform a soil test. You can then add fertilizers to create a richer soil for the roots. Dahlias also do well in slightly acidic soil. You can add compost, peat moss, and even fish eel if you want a more lush, full garden.

Whether growing in pots or containers, dahlias need a sunny, fertile area in which to grow. Slugs are particularly a problem, but they can be managed with a beer trap. Insects, such as cucumber beetles, can also damage dahlias. To avoid this problem, you can place a sheet of neem oil around the plant.

The soil should be rich in organic matter and well-drained. They are best grown in a slightly acidic soil, but you can also grow them in soil that is alkaline or slightly alkaline. You should add two pounds of compost to every 100 square feet of soil to give them the best growing conditions. If the soil does not drain well, dahlias may not thrive. If this happens, you should amend the soil or dig it up a few inches.

Since dahlias prefer temperate climates, they do not do well in harsh winters. Watering regularly is essential to ensure a healthy plant. Taller varieties should be staked to prevent bending or falling in heavy rain or high winds. Mulch helps to keep out weeds, and black mulch conserves heat. Remember to prune dead flower heads regularly to make sure the plant flowers throughout the entire season.


If you’re in the market for dahlias, you’re in luck! Dahlias are available in a wide variety of colors and are often sold in tubers. Dahlia tubers are healthy and can be divided to grow several more flowers. Dahlias for sale start blooming in early April, but shipping dates will vary based on local weather conditions. If the tubers freeze in transit or after delivery, we are not responsible for the damage. However, dahlias will be carefully packaged to avoid damage during shipping.

A dozen bloom of dahlias will run you about $5 to $6 per flower. However, if you purchase a bouquet of 20 blooms, they will run you about $190. This cost does not include burgundy dahlias, which are available all year long. You can also buy a bouquet of cut dahlias from local flower vendors. Keep in mind that dahlias are fragile and may not be as long lasting as those grown at a flower farm.

While dahlias are fairly easy to grow, they require water. Water is one of the few requirements that Dahlias have. The plants’ nonstop parade of flowers lasts from July to October. Dahlia flowers range in size from a little over an inch to 12 inches, and come in every color of the rainbow. Dahlia flowers are an incredible addition to any garden. You will be rewarded with a beautiful bouquet every time you visit them.
