Hollyhock Black Single

Hollyhock Black Single has stunning, silky flowers in the deepest purple — so dark they look black in the sun — with a bright yellow throat. For extra impact, grow them in front of a pale wall to really show off the colour. A great choice for wildlife-friendly gardens, as bees and butterflies love the open, single flowers. These bloom the year after sowing.

🌸 Flowering: June to August (from second year)

📏 Height: 150-180cm

🌿Perennial 

SOW
Start sowing from April to early June, either thinly in a seed bed or in trays or pots of seed compost. Cover them lightly with compost or vermiculite and keep them somewhere warm and bright—around 18–20°C is ideal. Later sowings can go in a cold frame. Germination usually takes 10–14 days. Once seedlings are big enough to handle, pot up the stronger ones and grow them on.

GROW
Plant out in September or October, spacing them 30-60cm apart in their final spot — the wider spacing helps improve airflow around your plants. They’ll settle in over winter and flower the following summer.

They like a sunny, sheltered spot, and might need a bit of staking once they shoot up.

ENJOY
The rich, dramatic colour might just spark a love for dark flowers. Plant near a light backdrop to really make them pop.
