Honesty Mixed

Lunaria annua 'Mixed' Honesty / Money Plant / Silver Dollar Plant 'Mixed'

A magical two-act cottage garden classic — spring sees clouds of vibrant purple and pure white four-petalled flowers above heart-shaped fresh-green leaves, but the real magic comes in late summer when the flowers transform into stunning silvery translucent seed pods that look like glowing silver coins, providing months of garden interest and the most prized "everlasting" dried stems you can grow at home.

This is the cottage garden's quietly magical two-act performer. The spring act is conventional and lovely — tall (75–90cm) branching stems covered in vibrant violet-purple and pure white cross-shaped flowers from April through June, contributing to early-season cottage colour and providing essential forage for emerging spring pollinators including the Orange Tip butterfly (Honesty is one of the butterfly's preferred larval food plants). But the second act is genuinely magical: as the flowers fade, they develop flat green seed pods that gradually ripen, then in late summer the outer layers peel away to reveal translucent silvery membranes beneath — perfect oval discs that catch the light like miniature moons or Victorian silver coins, glowing through autumn and winter as one of the most distinctive garden features any plant can provide. Hardy biennial (H7). RHS Plants for Pollinators recognised. Self-seeds prolifically.

A note on growing

Honesty follows the classic biennial cycle. Sow direct outdoors May–July, or in modules indoors at 15–18°C. Cover seeds with about 5mm of soil. Germination 14–21 days. Plant out into final positions in autumn (September/October) into partial shade or sun in moist humus-rich soil. Honesty is at its most reliable in partial shade with consistent soil moisture — the wild form grows naturally in damp woodland edges. Year 1: rosette of heart-shaped leaves. Year 2: spectacular flowering and seed-pod transformation.

For the silver seed pods: leave the flower stems standing after the petals drop — don't deadhead. The pods develop through summer, ripen in August/September, and the silver "moonlight" membranes are revealed when the brown outer papery layer is gently rubbed off (either by weather or by hand). For dried use, cut stems when the outer pods are fully brown and rub off the outer layers to reveal the silver.

⚠️ Same Brassicaceae family note as Hesperis — Cabbage White butterflies may occasionally lay eggs on the foliage; check for caterpillars in late summer and remove by hand.

Where it shines

In shaded woodland borders and dappled positions where the spring colour and the silver pods provide two seasons of interest. As an essential biennial partner to Foxgloves and Sweet Rocket — all three share the same conditions and overlapping flowering windows. As the most rewarding dried flower for autumn and winter arrangements — silver Honesty stems are genuinely magical in moon-themed displays and Christmas wreaths. In wildlife gardens, for Orange Tip butterfly larval support. As a self-seeding informal colony — once established, Honesty renews itself reliably for years.

Plant alongside

The classic biennial partnership: combine Honesty 'Mixed' with Foxglove 'Excelsior Mix' and Hesperis 'Purple' (Sweet Rocket) — all three share the cottage biennial cycle, flower simultaneously, and create a layered romantic spring-into-early-summer scheme. For colour reinforcement, the purple Honesty works beautifully with Geum 'Lady Stratheden' (yellow complementary) and Aquilegia 'Barlow Mixed' (matching pastels).
