Hollyhock Nigra

Most hollyhocks are pastel and fluffy. Nigra is neither. Also known as ‘The Watchman’, this heritage variety produces towering spikes of large, single, silky flowers in a shade of maroon so deep it looks like glossy black chocolate — a dramatic architectural exclamation mark that commands attention in any border.

The dark central eye and pale creamy style create a striking contrast that draws pollinators in from across the garden. A plant of real character, and one that looks extraordinary against pale stone walls or silver foliage.

• Alcea rosea 'Nigra' — Hardy Biennial
• Height: up to 2m | Flowers: June–September (Year 2)
• Sow May–July outdoors; flowers the following summer
• Full sun; well-drained soil
• Self-seeds reliably once established

Grow it with white cosmos or pale foxgloves for a border that moves between light and shadow with real intention.
