Boom Boom Yellow Dahlia Plants

Boom Boom Yellow: Ball Dahlia Tubers

Boom Boom Yellow brings a soft, primrose yellow burst of colour and versatility to borders from late summer until the first frosts.

The flowers are classically ball-shaped, each delightfully constructed petal curved inwards at the base to give a soft, quill-like look. You'll feel those tactile silken petals when you cup the perfectly spherical flower heads in your hands. The flowers are brilliant for cutting and bringing indoors for vases. The foliage is fresh green, the stems are sturdy and long, growing up to 90cm in height.

Growing Boom Boom Yellow Dahlias

All dahlias do best in deep rich soil with good drainage in a sunny spot. If it is windy they will need staking. They are greedy, thirsty plants so will need watering in dry spells, and they will always flower that little bit better if there is a bit of soluble food in the watering can once every couple of weeks.

It is generally more convenient to put support stakes in at planting time, rather than leaving it until there is foliage in the way.

Planting Companions for Boom Boom Yellow

That lovely pale yellow is a forgiving colour, so this dahlia will combine with all perennials in a wonderful display. Try planting in generous drifts with other dahlias in hot pinks, moody wine tones or vibrant oranges, such as deep burgundy Dark Spirit (that combination of buttery yellow and rich wine is delectable), or go all pastel soft with a romantic mixture of dreamy pinks, like Wizard of Oz. Another pairing would be with the gorgeous lime green umbels of fennel, Foeniculum vulgare; those delicate, flat, frothy flowers make a fabulous contrast to Boom Boom's structural qualities.

Did You Know?

It was introduced in 2009 by Smits, in the Netherlands.

If you ignore seed, Dahlias can be planted at three stages: as tubers, rooted cuttings and pot-grown plants.

Tubers can be planted at any time from March onwards. The hole should be at least double the diameter of the tuber laid out on the ground. Incorporate about 25% well rotted compost and if drainage is in any way doubtful then add plenty of horticultural grit as well. Plant one tuber per hole, leaving 60-80 cms between plants (depending on final size) and make sure the tuber is covered with 10-12 cms (4-5") of soil. This is important as it will insulate the tuber against frosts in March-May as they will take a couple of months to show.

Rooted cuttings, which are available from early April onwards, will need to be potted up and kept in a sunny and frost free place until they are ready to be planted out in mid May. Their treatment then is the same as for tubers except they are planted level with rather than 10 cms below the surrounding soil level.

Pot grown plants are not delivered until June, and are then planted out immediately in the same way as an established rooted cutting.

The more you deadhead, the more flowers you'll get.
