Description
Dahlia 'Lava Glow' brings a warm, glowing presence to the summer border, offering exuberant colour with a surprisingly refined touch. Its generously sized, semi-double blooms open in luminous peachy-orange tones softly brushed with pink, while the richly textured, anemone-style centre glows with apricot and gold, giving each flower remarkable depth and movement. As the season progresses, Dahlia 'Lava Glow' only becomes more expressive, the flamboyant, fluttering petals dancing above fresh green foliage and slender, dark stems. 'Lava Glow' is a dahlia variety that commands attention without overwhelming its neighbours, lending itself beautifully to contemporary planting schemes as well as more relaxed, painterly borders.
The open form of Dahlia 'Lava Glow' makes it particularly attractive to pollinators, adding life and gentle motion to the garden. Reaching a modest, well-balanced height, Dahlia 'Lava Glow' is ideal for the middle of mixed borders and excels in cutting gardens, where its long-lasting blooms bring drama and warmth indoors. In fertile, well-drained soil and full sun, Dahlia 'Lava Glow' rewards regular feeding and deadheading with a long flowering season from midsummer well into autumn. Among anemone-flowered dahlias, it truly stands apart—its exceptionally large, extravagant blooms and extraordinary colouring placing it firmly in a class of its own.

Useful information
-
Dahlia 'Lava Glow' 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 'Lava Glow' 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.
