Dahlia Cactus Gelber Vulcan

(inc. 20.0% VAT)



Nothing lifts the garden and the spirits quite like an enormous, bright yellow dahlia – as ‘Gelber Vulcan’ demonstrates with panache. Joyous and exuberant, this stunning variety will bring a sense of elation to your garden. Named ‘Vulcan’ after the Roman god of fire, the vivid golden blooms blaze like sunshine on a scorching summer’s day. With dinner-plate sized heads and towering stems, this flamboyant plant is an extrovert amongst beds and borders. The flowers burn bright from summer well into autumn, revivifying your display towards the end of the season and bringing brightness to the greyest of days.

Care Guide

To grow Dahlias, select a sunny spot with well-drained soil, and dig a 30cm deep hole. Plant the tuber 10cm below the soil surface, spacing multiple tubers 45cm apart, or 90cm for taller varieties. Water consistently, maintaining moist but not saturated soil and protect new shoots from slug damage with eco-friendly methods. Feed plants during the blooming period with liquid plant food. Provide support for stems which will reach 60-90cm tall depending on variety. Enjoy spectacular blooms from late summer until first frosts. Cut or deadhead the flowers regularly for a continually flourishing display. Once blooming has finished, cut back foliage before lifting, drying and storing the tubers in peat-free substitute, in a frost-free place until the following spring.
