Description

Set your plantings alight with the appropriately named Dahlia 'HS Flame', and keep the fire alive in your garden all through summer and autumn! This single-flowered dahlia combines an elegant flower-form with red-hot colours, set gorgeously against almost-black dramatic foliage and stems. The blooms of Dahlia 'HS Flame' are fiery red, turning a glowing yellow towards the base, where a paprika-red disc and golden anthers set it off to perfection. This plant flowers profusely, producing continuous blooms held up high above the foliage, giving maximum visibility and impact.

Dahlia 'Happy Single Flame' has an award-winning combination of great garden performance, versatility and reliability. These qualities have secured it an Award of Garden Merit (AGM) from the Royal Horticultural Society (RHS). It can used wherever you’d like to give your plantings a late summer boost of colour and interest, and should continue flowering for many weeks given the right conditions – a sunny spot is best, with good, fertile soil. At around 80cm high, it works well in the border and is also a lively container plant, especially if the growing tip is pinched to give a bushier hibit. Single-flowered dahlias like 'HS Flame' have the added benefit of attracting pollinators such as bees and butterflies to the garden, making this an excellent choice for the wildlife-friendly gardener.

Useful information

    • Dahlia 'HS Flame' is half hardy, which means that it should be kept frost free over winter and during spring.

    • For best results, start your dahlia tubers in temporary pots in a
      greenhouse in March or April to grow on to transplant outside later in the season—this will give them a head start.

    • Alternatively, you can plant the Dahlia 'HS Flame' tubers directly outside in May.

    • Plant with the stump of last year's stem facing upwards. The tuber should be fully submerged but with the stump just below the soil surface.

    • Plant one tuber per 8-10" pot if growing on during spring. When
      planting outside, space the tubers around 30-50cm apart from each other. Compact varieties don’t need so much space.

    • Water-in thoroughly after planting and continue to water regularly once in full growth, but only when the soil appears to be nearly dry.

Dahlias in 60 seconds

Dahlias like full sun and a free-draining soil, and should be lifted and stored in winter, or at least protected with peat or straw. Dahlia flowers can range from 5 to 25cm in diameter and those magnificent larger-flowering dahlias might appreciate a little extra support with canes!
