Honesty 'Mixed' Seeds (Lunaria annua)

Lunaria annua, commonly known as Honesty, is a robust Hardy Biennial (H7). It is perfectly suited to the UK climate, surviving temperatures as low as -20°C. It operates on a two-year cycle: growing a leafy rosette in its first year and flowering followed by seed production in its second.

The Silver Membrane: The translucent "coins" that make Honesty famous are actually the central membranes of the seed pods. To reveal them, wait until the pods have turned completely brown and brittle in late summer. Gently rub the pod between your fingers to peel away the outer skin and release the seeds, leaving the shimmering silver membrane intact.

Butterfly Hero: Honesty is a critical plant for British biodiversity. It is a primary nectar source for the Orange Tip butterfly in spring and acts as a vital food plant for their caterpillars. By growing Honesty, you are directly supporting one of the UK’s most beautiful spring butterflies.

Honesty is one of the easiest and most reliable biennials to establish from seed.

How to Sow:
Sow directly outdoors from May to July. Scatter the large, flat seeds onto finely raked soil and cover to a depth of about 5mm. They germinate readily in 14-21 days. If sowing in trays, transplant them into their final positions in autumn while they are still small, as they develop a long taproot that dislikes being disturbed once mature.

Where to Plant:
They thrive in partial shade or full sun. Honesty is naturally a woodland edge plant, making it an excellent choice for those tricky spots under deciduous trees or against north-facing fences where other flowers might struggle. It is remarkably tolerant of most UK soil types, including heavy clay.

Ongoing Care:
Once established, Honesty requires virtually no maintenance. To ensure a harvest of "silver coins," leave the seed heads on the plant until they are dry and papery before cutting the stems for indoor display. If you allow some seeds to fall, the plant will happily self-seed, providing you with free flowers year after year.

Honesty blooms in late spring, making it a perfect partner for structure and spring bulbs. Pair it with these available stars:

• 🦊 Foxglove 'Excelsior Mix': The Woodland Duo. Both Honesty and Foxgloves thrive in dappled shade and provide excellent vertical structure. Planting them together creates an effortless, naturalistic "secret garden" corner that pollinators will adore.
• 🌷 Tulip 'Angelique': The Spring Finale. The vivid purple and lilac tones of Honesty provide a lush, wild backdrop for the soft pink petals of 'Angelique'. The leafy Honesty also helps to hide the fading tulip foliage as the season progresses.

Sow in summer for lush leafy growth in Year 1, followed by vibrant spring flowers and shimmering autumn pods in Year 2.
