Nigella ‘Mulberry Rose’ Seeds

Antique rose-berry blooms nestled in a cloud of fine, ferny foliage. As these flowers mature in the sun, they deepen from soft blush to moody mulberry, followed by magnificent burgundy-striped seed pods for winter vases.

If you find the standard blue Nigella a little too “wild,” let me introduce you to ‘Mulberry Rose’. This stunning variety is a masterpiece of colour evolution. The paper-thin, ruffled blooms open a delicate, pale pastel pink, and as they mature in the sun, they deepen into a rich, vintage rose-berry tone.

Nestled in a ruff of fine, ferny foliage (the “mist”), these flowers look like antique porcelain. But the beauty doesn’t stop when the petals fall. The centre of the flower swells into a magnificent, balloon-like seed pod striped in burgundy and green. These pods dry perfectly, providing architectural interest for winter vases and wreaths long after summer has faded.

Understanding the Plant

Nigella damascena ‘Mulberry Rose’ is a Hardy Annual (H3/H4). It is a charming, low-maintenance choice for UK gardeners, known for its “self-sowing” natureif you leave the seed pods to dry on the plant, it will often return in the same spot spring after spring.

The Colour Evolution: Unlike many flowers that fade in the sun, ‘Mulberry Rose’ actually darkens. The blooms start as a soft blush and deepen into a moody, dusky mulberry. This makes a single patch look dynamic as old and new flowers mingle together.

Wildlife Support: Listed on the RHS Plants for Pollinators list, Nigella is a vital nectar source for bees in mid-summer. The complex, semi-double flowers provide a stable platform for pollinators to feed on.

Growing Guide

Nigella is one of the most reliable “scatter and grow” seeds, making it a favorite for both beginners and experts.

How to Sow:
Sow directly outdoors in September for early summer flowers, or March to May for a summer-long display. Scatter seeds thinly onto raked soil and cover lightly (about 3mm deep) as they germinate best with a light covering. Seedlings usually appear in 14-21 days.

Where to Plant:
They thrive in full sun or light shade. They are not fussy about soil and will even flourish in gravel gardens or poor soil. Avoid over-fertilizing, as rich soil encourages the plant to produce more green foliage (the “mist”) and fewer of those beautiful mulberry blooms.

Ongoing Care:
Maintenance is minimalNigella has sturdy stems and rarely needs staking. If you want a continuous supply of flowers for the vase, deadhead the spent blooms regularly. However, if you want the striking burgundy seed pods for drying, leave the flowers to set seed naturally.
