Basic Facts about the Black Dahlia
Family: Asteraceae
Genus: Dahlia
Life Cycle: Perennial
Bloom Period: Mid-summer to fall
Black dahlia belongs to the Asteraceae family and is a variety of the Dahlia genus. This means they belong to the same family as chrysanthemums, daisies, asters, dandelions, and sunflowers.
They are warm-season perennials that spread from tubers underground.
Despite there being over 20,000 varieties of dahlias, only a little over 20 varieties are black dahlias, so they’re a very rare type of dahlia. They also only bloom from mid-summer to fall, making them even harder to get.
Dahlias generally can be eaten, so the same goes for black dahlias. However, you have to be more careful with them compared to other dahlia varieties.
Some black dahlias contain harmful chemicals, so they’re dangerous when taken. They’re toxic to dogs and cats, so make sure they’re far from their reach.
Physical Descriptions of the Black Dahlia
Despite being named Black Dahlia, these flowers aren’t really black. They have a dark crimson and purple tint that is sometimes very dark, causing them to appear black.
Some black dahlias also have bright yellow centers that perfectly contrast their dark-colored petals.
The size of black dahlias depends on the variety. Some can have a diameter of a few inches to a foot and a height of 2 to 6 feet.
Their shapes and structure also depend on the variety. Some dahlias can have single or double blooms and ball-shaped or star-shaped heads.
Origin of the Black Dahlia Flower
Black dahlias are a variety of the Dahlia genus that has deep red and purple colors, so their origin is essentially the same as any other dahlias out there.
Abbe Cavanilles, director of Botanical Gardens in Madrid, named dahlias after the Swedish scientist and environmentalist Andreas Dahl. But these flowers didn’t originate in Sweden or any other European countries.
Black dahlias were first seen in Mesoamerica, mainly in Mexico, El Salvador, Honduras, Nicaragua, Costa Rica, and Guatemala. Because these countries don’t have severe winters, dahlias thrive as perennials.
Unlike today when many use dahlias as decorations and gifts, they were mostly eaten back in the day. Many Aztec people also used their hollow stems as water canes.
The first time these flowers were grown in Europe was in the 18th century at the Botanical Gardens in Madrid. After that, many other European countries also started growing them, which led to them being named after a Swedish scientist.
Today, you’ll find over a thousand varieties of dahlias, with every color you can think of. The varieties of black dahlias have also evolved and multiplied because of many developments.
However, black dahlias are still not that common in home gardens compared to other varieties of dahlias.
Meaning and Symbolism of Black Dahlia Flower
The symbolism of flowers is mainly derived from their colors, like how red is often associated with love and passion, while yellow is associated with happiness and positivity.
The same goes for the black dahlias, that’s why their associated meaning is not that bright.
Black has always been associated with some dark and sad meanings. The darkness of the black dahlia and its red tint that’s similar to blood made the flower a symbol of death, mourning, brutality, and sadness.
This symbolism became even more apparent when Elizabeth Short was gruesomely murdered in Leimert Park. During the media coverage of the murder, Short was referred to as black dahlia.
However, not all varieties of black dahlias have bad meanings. Some black dahlias that have more of a purple hue are used to symbolize power and ambition.
Kinds of Black Dahlia Flowers
There are just around 20 different types of black dahlias, making them one of the rarest flower families. Their dark, mysterious, and dramatic hue, however, continues to pique the interest of many.
Here are some of the most popular varieties that may capture your attention:

The core petals of this type are a deep, rich chocolate brown, while the tips are a dark, rich crimson. They can reach a diameter of 4 to 6 inches but are quite light compared to other varieties of the same size since they need smaller amounts of water.

These flowers have semi-double blooms and velvety deep red petals that make them elegant and perfect for formal decorations.
Taking Care of Black Dahlias
Black dahlias are extremely rare, so it’s understandable to want to prolong their life when you receive them as gifts. Dahlias, though, have a relatively short vase life of only 3 to 4 days.
There are some types that may stay alive for 7 to 12 days, but there are not many of them.
Here, we’ll help you maximize their life, and possibly extend it to up to 2 to 3 days.
Which type of black dahlias last the longest?
If you want black dahlias that last long, consider the size of the flower head.
Smaller and more compact black dahlias usually last longer than the larger ones because the dinner plate-sized blooms are usually too heavy for the stems to support.
Another thing you should consider is the form of the flowers. Choose the ball-type and dome-shaped black dahlias that usually last longer than the uniquely shaped ones.
Tips to Make Black Dahlias Last Longer
Here are 7 things you can do to extend your beautiful black dahlias life:
1. Cut the stem at an angle
Your black dahlias will have a much larger surface area for water absorption if the stem is cut at an angle.
It would be even better if you’ll cut it underwater since this prevents air bubbles from forming. We want to avoid air bubbles as much as possible since they block water absorption, causing the flower to die and wither.
2. Remove any leaves that will touch the water
Make sure that all leaves staying on the stem don’t touch the water. This is because water causes leaves to decay and release bacteria, which can be harmful to the flowers.
3. Use a clean and clear glass vase
The glass material of the vase will prevent chemical reactions from forming between the vase and water, making it an excellent choice for cut black dahlias.
The black dahlias also benefit from having more airflow thanks to a transparent glass container. Don’t worry about getting musky and cloudy water since dahlia stems aren’t susceptible to that.
4. Soak in hot or warm water with flower food
Use hot or warm water for cut black dahlias. Black dahlias usually last longer in warm water rather than in cool tap water.
Just make sure, though, that if you put other flowers with the dahlias, they can tolerate warm water. Some flowers may die if placed in warm water, so better to check first.
Add some flower food too, as it helps in keeping the flowers fresh.
5. Prop the head up with other blooms
Black dahlias usually have big and heavy flower heads, so they can be too heavy for the stem to support. Use other flowers to give the stem a bit of support in holding the bloom.
6. Clean the vase and change the water every two days
Bacterias will usually grow in the vase water if it’s not regularly changed, which can cause your black dahlias to die faster. Hence, you should change it every two days to make sure your dahlias are safe.
Make sure to clean the vase too, since the bacteria that formed there may mix with the new and clean water.
7. Cut the stems every time the water is changed
Every time you change the vase water, trim the stem to remove any sections that have developed air bubbles. This will help the flowers retain water and look beautiful for longer.
