Dahlia Cactus Blue Diamond

(inc. 20.0% VAT)



Dahlia 'Blue Diamond' is a rare gem indeed. The violet hue of this bloom resembles the enchanting eyes of the iconic actress Elizabeth Taylor, commanding the attention of onlookers. Just as Taylor was famous for her extensive jewellery collection, this hard-to-find dahlia variety will be a valuable addition to your botanical collection. The cactus-type, elongated petals taper gracefully, evoking a Hollywood elegance. The flowers are poised on tall, sturdy stems amongst lush, verdant foliage. Producing plentiful blooms from July until the first frosts, this floral treasure will soon become the jewel in the crown of your garden.

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.
