This August, our focus is Dahlia. It is one of most popular flowers in Summer and Autumn for wedding and event work.


Dahlias are native to Central America, Colombia and Mexico and are commonly grown as garden plants. The Aztecs grew the dahlia for food, ceremonial purposes and for decoration.  Belonging to the Asteraceae family (same as Helianthus and Chrysanthemums), they get the name from the Swedish botanist, Dr Anders Dahl.

Dahlias are famous for their bright, cheerful flowers with waxy petals. In Japan the Dahlia is called Tenjikubotan which translates to ‘Peony of India’.

Peak season is generally July through to November, depending on the weather. They are grown indoors in greenhouses and outdoors. When the first frost happens, the season is over outdoors.

Types of Dahlia varieties

There are several types of this wonderful bloom available with Triangle Nursery.


Standard or regular dahlias is the terminology that the traders tend to use when they’re referring to the Decorative and Waterlily types.


Decorative dahlias have double blooms and their petals are normally broad and flattened.  Examples of this type of dahlia are Diana’s Memory (pale pink/yellow), ‘Salsa'(dark red) and ‘Karma Choc’ (dark red to maroon).


The Waterlily type also have double blooms.  But their broad petals are slightly curled up along their length, giving a saucer-shaped appearance to the flower.

Pompons, sometimes referred to as ‘Poms’ by the traders. They  have small, compact flower heads and their petals curl up along the whole of their length.
Examples of this type of dahlia are ‘Viking’ (red), Ivanetti (dark red) and ‘purple fox’ (purple).

Semi Cactus & Cactus

‘Spikey’ or ‘spider’ is sometimes how the traders describe the Semi Cactus and Cactus varieties of dahlia. They have narrow petals, with the Semi Cactus petal shape broadening out a little at the back of the flower.

Dahlia Orange

Dahlia Chat Noir

It has to be understood that dahlias are grown for their flower heads – the leaves will always look scruffy and discoloured – this is perfectly normal.

Quantities & Prices

Dahlias are available in the wholesale flower markets as cut flowers and are sold in wraps of 10 or 20 stems. Prices can fluctuate, but generally start around £0.50 to £1.15 pence per stem, depending on the type of variety, availability and time of year.

General Advice

To get the best from your wholesale cut dahlias please read the care instructions below carefully:

Cut the stems at a 45 degree angle with a sharp knife. Why? This enables the stem to stand on a point, allowing water to be in contact with the cut surface. Cutting underwater ensures that air does not enter the stems. Strip any foliage that will be underwater in the vessel. Bacteria will form if foliage is in the vase water and cause premature demise of your beautiful blooms.

Fill sterilised buckets with luke warm water and add flower food. Leave over night to condition before using. Never leave cut flowers in direct sun light, near a radiator, in a draft or near fruit. (The gas used to ripen fruit will harm most flowers). Keep the dahlias in a cool place and always keep out of the way of children.

If possible, change the water daily and ensure the vase or container is cleansed of all detritus.
