Black Dahlias Flower – Everything You Need To Know

If you are looking for a unique and striking flower to add to your garden, then look no further than the black dahlia.

This dark bloom is sure to turn heads and will add a touch of drama to any setting. Easy to grow and care for, the black dahlia is a great choice for any flower lover.

Let’s learn about the black dahlias flower.

What Is Black Dahlias Flower?

Dahlia refers to many species of the Dahlia genus. Any dahlia species or variant with dark red blooms is considered a black dahlia. As a result, the black dahlia’s history is quite similar to that of other dahlias.

Dahlias are native to Mexico’s mountainous areas, as well as a few sites in Guatemala, Honduras, El Salvador, and other Central American countries. Dahlias bloom as perennials in these areas since there are no strong frosts.

While these early dahlias continued to bloom, indigenous people prized dahlia blossoms for various reasons. Some species’ tubers were employed as a food source. The long, hollow stems of the tree dahlia were also employed to convey water.

Although Europeans first saw the dahlia in the 16th century, the flowers did not arrive in Europe until the 18th century. Tubers and seeds initially arrived in Spain, from whence they were distributed across Europe.

Over time, humans crossed dahlias to create new kinds, including black dahlias.

What Do Black Dahlias Flower Symbolize?

Flower symbolism is mostly concerned with the color of the blooms and rarely considers their size and shape.

Black dahlias are frequently associated with unpleasant feelings such as betrayal and grief. This, however, is merely one interpretation of the significance of dark-colored flowers. The black dahlia’s rich purple color can also indicate passion and strength.

Black is also the most attractive of all hues, and black flowers may bring elegance and exquisiteness to your landscape. It’s also worth noting that the symbolism of a single color can change when different colors are combined.

Different color varieties of dahlias are frequently combined with black dahlias, creating a sharp contrast between the different flowers and removing much of the potentially negative symbolism of the dark flowers.

How To Grow And Care For Black Dahlias Flower

Black Dahlias Flower - how to grow

Dahlias are a type of flower that can be grown from bulbs. Plant the tubers outside in the spring once the soil temperature reaches 60ºF.

They need the right conditions to grow, including full sun and water in dry soil; They also greatly benefit from fertilizing every month or so during their growing phase!

Soil Requirement For Black Dahlias Flower

Dahlias have comparable soil needs to most other perennial herbaceous plants, preferring a somewhat acidic, rich, and well-draining soil.

Most general-purpose potting mixes fit this description, thus most types of soil will work. If you don’t supply fresh soil and grow dahlia in a soil bed that has been depleted by other plants, you may need to replace the soil or offer some fertilizing.

Fertilizing Black Dahlias Flower

Black dahlias should be fertilized with a modest amount of nitrogen.

High nitrogen fertilizers might stifle blossoming and harm the roots. Fertilizer should be applied sparingly and evenly throughout the growing season, from early spring to late summer.

As always, prevent over-fertilization and the accumulation of fertilizer salts in the soil.

The common signs of over-fertilization are wilting and leaf burn. Fertilizers high in nitrogen may result in luxuriant green growth but scant blooming.

Dahlias should be fertilized only after they have produced a substantial quantity of foliage; this implies that no fertilizer should be used on newly buried tubers or seedlings less than a month old.

Watering Black Dahlias Flower

Watering frequency will vary depending on soil composition and weather conditions, but in general, dahlias require moderate watering — at least once a week and occasionally twice a week.

However, over-watering and waterlogging can cause tuber rotting, which occurs when most of the oxygen in the soil is displaced by the extra water. It’s recommended to figure out the appropriate watering schedule by allowing the top layer of soil to dry up before watering again.

Shortly after planting, the tubers are highly sensitive to over-watering and already have an abundant water supply – water no more than once a week until the tubers begin to develop.

Black Dahlias Flower Blooming

Dahlia tubers typically take around 2 months from planting to bloom.

Planting from seed will take at least twice as long, and the immature plants may not blossom at all in their first year.

Dahlias frequently benefit from deadheading since it extends the flowering time and forces the plant to produce more blooms.

Deadheading is the technique of removing blooms from a plant as they begin to die. This stops seed development and saves the plant a lot of energy that can be used to produce new blossoms.

Because deadheading prevents seed generation, it’s best to leave part of your dahlia plants alone in order to gather seeds from them.

Varieties Of Black Dahlias Flower

Dahlias come in hundreds of types, and seed packs are sometimes mixed hues. Only a few dozen types have dark enough blossoms to be called black dahlias.

Blackjack, Black Embers, Black Satin, and Arabian Night Dahlias are the four most frequent black kinds, beginning with the one with the biggest blooms.

BlackJack

This is not just a black dahlia variation, but also a ‘dinner plate’ variety. The ‘dinner plate’ aspect of the title is not an exaggeration; the blooms of this dahlia may reach dinner plate size – up to one foot across. This is a dahlia with incredibly dark blooms that might almost appear black.

Black Embers

This is a dahlia cultivar that is lighter in color than the blackjack dahlia — it produces rich red flowers that are deeper in the center. The blooms are smaller, and this kind is not suitable for a dinner dish.

Black Satin

Very similar to black embers, but with somewhat smaller blooms that reach roughly 5 inches in diameter.

Arabian Night

A variant with even smaller blossoms that can reach a diameter of 4 inches. This is an award-winning Dahlia variety that is highly appreciated, yet it looks a lot like the black satin and black embers dahlias.

Do Black Dahlias Flower Grow Better Indoors Or Outdoors?

Dahlias may be grown both indoors and outdoors, and the black dahlia types are no exception.

Dahlias are a popular outdoor plant that is often grown in a garden bed filled with potting soil.

Dahlias consume a lot of energy during blooming since they generate huge flowers – indoor plants will not blossom if not given enough light, which is why they should be grown on a south-facing windowsill.

How Much Sun Does Black Dahlias Flower Need?

Dahlias, like other herbaceous plants, want full light. This plant has a limited leaf area and relies on a high light intensity to gather nutrients in its tubers.

Its enormous blooms require a lot of energy to create, and the plant will not flower properly unless it gets at least 6 to 8 hours of direct sunlight every day.

Typically, the blooming cycle depletes the nutrients in the tuberous roots, and the plant replenishes them over the summer.

Without enough light, the plant may blossom later the next year or not as all since its nutritional supplies are depleted.

FAQs

Black Dahlias Flower FAQ

Are Black Dahlias Flower Edibile?

Surprisingly, all portions of the dahlia plant are edible.

The leaves, on the other hand, are not often consumed and may contain oxalic acid and tannins, which must be cooked out before eating. The tubers and flowers of the plant are the most widely consumed parts of the plant; the tubers taste similar to carrots but are less sweet, and the flowers may be turned into tea.

Obviously, if you want to taste your dahlia plants, you must first ensure that they are dahlias and not other flowering plants that seem similar.

Do Black Dahlias Flowers Grow Well In A Potting Container?

Dahlias thrive in containers.

They will develop into a tiny, 1-foot-tall shrub with lesser blooms if their roots are constrained.

Dahlias grow well in big pots and can reach full size (4-5 feet tall), but they nearly always need to be planted outside in full light.

Smaller flowering varieties are typically better suited for indoor growing in compact spots. Starting dahlias from seed is preferable if you want to grow them in tiny potting containers – most dahlia tubers are rather big and difficult to bury in a small container.

How Big Does The Black Dahlias Flower Plant Get?

Almost all dahlia cultivars achieve maturity.

When grown outside under ideal conditions, it may reach a height of 4 to 5 feet.

Dahlias may easily be kept to a height of one foot when cultivated in a flower container.

Those little, potted dahlias will still produce the same flowers they do outside, albeit somewhat reduced in diameter. The flower stalk is the plant’s tallest point, reaching 1-2 feet above the leaves.

Which USDA Zones Are Suitable For Black Dahlias Flower?

Dahlia may be cultivated in most USDA zones, however, the yearly cycle will vary greatly depending on the winter temperatures.

The plant will act like a perennial in USDA zones 8-11 and will not die over the winter months.

Winter frosts may destroy the plant’s leaves in USDA zones lower than 8, but the tuberous root will survive, allowing the plant to re-emerge in the spring.

In USDA zone 3, additional precautions must be taken to protect the plant’s sleeping tubers from frost — layers of mulch or a plastic sheet may be required to give some insulation from the low overnight temperatures.

How Can I Know If My Black Dahlias Flowers Are Rotting?

Dahlia, like many other plants, can get tissue rot if the soil isn’t properly draining.

Dahlias can succumb to stem rot if densely grown plants are sprayed with a spray nozzle and a lot of the moisture lingers on the stems and leaves.

Root rot is difficult to identify and frequently begins with wilting. All rotting concerns may be remedied by ensuring that the soil drains adequately and that the watering frequency is lowered so that the soil surface dries between waterings.

How Can I Know If My Black Dahlias Flowers Are Not Getting Enough Light?

The most typical indicators of inadequate light are poor, sluggish development, and a lack of blossoming.

This is easily distinguished from other reasons by examining the light levels on the plant leaf.

Densely planting a lot of dahlias next to one another will result in overlapping leaves and a fewer quantity of blooms so allow at least a foot and a half between each plant.

If you are looking for a unique and outstanding flower to adorn your garden, look no further than the black dahlia.

This dark bloom is sure to impress and will add drama to any setting. Easy to grow and easy to care for, daisies are a great choice for any flower lover.

What Are Diseases That Black Dahlias Flower Can Get?

Many fungal and viral infections, including the common mosaic virus and botrytis – a fungal issue that causes brown patches on the leaves – can attack dahlia plants.

Aster yellow is a bacterial disease that is also frequent in dahlia plants. It begins with the yellowing of the foliage and can also impact the blooms.

Over-watering can considerably minimize all fungal and bacterial concerns, but there is no therapy for viral illnesses. The common mosaic virus causes a yellowing of the leaves in patches with poorly defined boundaries.

If you suspect a viral ailment, the only way to prevent the virus from spreading is to remove the infected plants.
