Nemophila Penny Black - Penny Black - Nemophila menziesii - Dark blooms, compact habit, decorative form - Fresh Seeds

Nemophila Penny Black (Nemophila menziesii) is a distinctive annual with an elegant, unusual flower colour. Its low, gently trailing stems grow to about 15 cm, forming neat green groundcover. The small blooms are deep, almost black purple with a clear white edging, creating a finely painted look that stands out beautifully in garden displays. This variety is ideal for creating dense, flowering carpets in beds and rock gardens, along path edges, and in containers, where it brings a refined accent through the summer months.

Sowing depth

Sow the seeds about 0.5 cm deep. A shallow covering helps maintain moisture while allowing the light conditions needed for germination. Sowing too deeply can delay emergence.

When to sow outdoors

Sow outdoors in April or May, once the soil has warmed and the risk of frost has passed. In a milder spring you can sow earlier within this period, while in cooler conditions it is better to wait until early May for quicker, more even germination.

Spacing

Allow about 20 x 30 cm between plants. This spacing lets the plants spread freely to form compact, flower-filled patches, while also improving airflow and supporting better flowering.

Flowering period

Nemophila Penny Black flowers from June to September. The blooms last well and pair especially nicely with lighter coloured annuals, adding depth and contrast to summer planting.

Growing tips

Grow in free-draining, moderately fertile soil with plenty of humus. Avoid heavy ground and places where water collects, as excess moisture can harm the roots. Choose a sunny or lightly shaded spot. In full sun it flowers most generously, while light shade can help the petals stay fresh for longer. Shelter from cold, exposed winds for the best display.
