Dahlia Decorative
Blitzer
Dahlia Blitzer is a bold decorative dahlia with large mandarin-orange blooms that deepen towards the centre, bringing warmth and real impact to summer garden displays. Flowering from mid-summer through autumn, it produces masses of eye-catching flowers on upright stems, making it a superb choice for borders and cut flower gardens alike. Growing to around 100 cm tall, this variety adds strong colour and structure to a sunny, well-drained spot, and its vibrant blooms are especially effective for bright, energetic planting schemes.
