Delphinium Paramo Black Velvet ('Barthirty') (PBR) (Paramo Series)

delphinium

Product Image
Exuding elegance and sophistication, this upright herbaceous perennial boasts densely-packed spires of semi-double, dark purple-blue flowers that rise majestically above a mound of deeply-cut foliage.

Delphinium Paramo Black Velvet lives up to its name with blooms reminiscent of luxurious fabric, featuring an almost black centre. Flowering throughout summer on strong, branching stems, this cultivar is a magnet for pollinators and a standout in both borders and containers. Specifically bred for cut flower production, it provides abundant blooms for fresh and dried arrangements. The intense colour of the flowers creates a stunning contrast against the green foliage, making it an ideal choice for creating dramatic backdrops in cottage gardens or dedicated delphinium beds.

How to care for Delphinium Paramo Black Velvet ('Barthirty') (PBR) (Paramo Series):

For best results, plant in an open spot with fertile, freely-draining soil and protect the young foliage against slug and snail damage.

During the growing season, apply a seaweed or balanced liquid fertiliser every 2-3 weeks. While wearing gloves, stake the emerging flower spike with a stout bamboo cane and tie it in as it grows.

Cutting back the faded flower stems to a flowering side shoot will help encourage a second flush of flowers.
