Lunaria

Lunaria annua

flower

Lunaria, commonly known as honesty plant or money plant, is a biennial or short-lived perennial grown for its distinctive papery, translucent seed pods that resemble silver coins. The plant produces fragrant purple, pink, or white flowers in spring before developing these ornamental seed heads that are prized for dried arrangements. It self-seeds readily and naturalize well in gardens.

Growth Stages

1

Seed Germination

10-14 days

Tiny seedlings emerge with cotyledons visible. Seeds need light exposure and cool temperatures to germinate.

Do not cover seeds; sow on soil surface. Maintain moist conditions. Germinates best in fall or early spring.

2

Vegetative Growth (First Year)

6-8 weeks (by fall) or overwinter

Rosette of elongated, coarsely toothed leaves develops close to the ground. Plant focuses on foliage production.

Water regularly during dry spells. Thin seedlings to proper spacing. Remove weeds. No fertilizer needed if soil is moderately fertile.

3

Flowering

4-6 weeks

Tall flower spikes emerge in spring, producing abundant four-petaled flowers in purple, pink, or white, arranged in loose racemes. Flowers are fragrant.

Deadhead spent flowers if you want to prevent excessive self-seeding, or leave flowers to develop seed pods. Provide stakes if plants become leggy.

4

Seed Pod Development

6-8 weeks

After pollination, flat, round seed pods develop that are green initially. Pods grow to 1.5-2 inches wide. Outer seed case remains but develops papery quality.

Allow pods to dry and mature on the plant. Do not harvest too early or translucent interior will not fully develop. Water moderately.

5

Seed Pod Maturity & Harvest

2-4 weeks after pods fully mature

Seed pods turn pale green then tan, becoming completely dry and papery. Outer seed case falls away, revealing translucent silvery inner membrane with dark seeds.

Harvest seed pods when outer case begins to peel. Hang bundles upside down in a dry, airy location to cure. Allow self-seeding or collect seeds for next season.

Companion Planting

Plant with:

Avoid planting near:

Brassicas (in large quantities, as both attract cabbage moths)

Common Pests

  • Use row covers during spring, hand-pick caterpillars, or apply neem oil. Avoid planting near brassicas to reduce pest pressure.

  • Use insecticidal soap or neem oil spray. Row covers on young plants prevent infestations. Remove plant debris.

  • Ensure good air circulation; thin dense foliage. Apply sulfur dust or potassium bicarbonate spray if severe. Water at soil level, not foliage.

Harvest Tips

Harvest seed pods in late spring or early summer when the outer seed case begins to split and peel away, revealing the silvery, translucent inner membrane. Cut stems with mature pods and hang upside down in a dry, well-ventilated space for 2-3 weeks to finish drying. Gently rub or allow the outer case to naturally fall away. Collect seeds in fall if you wish to propagate new plants, or allow self-seeding in the garden.

Fun Facts

  • 🌱 Lunaria gets the common name 'money plant' from its silvery, coin-shaped seed pods that resemble silver money when the outer seed case falls away.
  • 🌱 The translucent inner membrane of the seed pod is so distinctive that it remains a sought-after material in dried flower crafts even after the seeds are gone.
  • 🌱 Lunaria self-seeds prolifically, sometimes escaping cultivation and naturalizing in woodlands and hedgerows where it can spread for years from a single planting.
