(Lunaria annua)

Annual honesty, also known as Money plant, Moonwort

The delightful annual honesty has compelling pollination habits, entirely reliant on bees, its primary pollination partners. Its vivid colors and arresting aroma serve as irresistible attractants for these industrious insects. Through this plant-bee dance, annual honesty’s unique pollination mechanism transpires, typically during spring, ensuring the process is time-efficient and beneficial for both parties.

How Does Pollination Occur in Annual Honesty?

Annual honesty produces cross-shaped, four-petaled flowers clustered in racemes. The flowers can be purple, white, or pink and typically bloom between spring and early summer. These flowers are characterized by strong fragrance which is instrumental in attracting pollinators.

Annual honesty uses primarily cross-pollination. The plant releases pollen grains from its anthers which are then transferred to the stigma of the same flower or another flower by pollinators.

How Can You Enhance the Pollination of Annual Honesty?

Plant Variety

Birds, bees, and beetles prefer flowers with single-layer petals and an open form, as these make accessing nectar easier. Plant varieties in your garden that attract these insect pollinators. They are likely to appreciate bright colors like yellow and blue.

Water Source

All pollinators need water. Create a small, shallow water source and place it near the Annual honesty plants. Fill it with stones or twigs so insects like bees, beetles and butterflies have a place to land and drink without the risk of drowning.

Pesticides

Avoid or limit pesticide usage, especially during the flowering season. Pesticides could harm or deter these pollinators. When necessary, opt for organic or less harmful pesticides and apply them late in the day when pollinators are less active.

Habitat

Consider creating an insect-friendly habitat. For instance, a log pile or an undisturbed area of grass and wildflowers can provide a suitable space for beetles and bees to nest and lay eggs. These habitats can attract these pollinators to your garden or farm, contributing to natural pollination.

How Can You Determine if Annual Honesty has Been Pollinated?

Flower Change

Annual honesty's blossoms that have been pollinated often fade in color and drop their petals, leaving only the developing seed pod.

Seed Pods Development

In a successfully pollinated annual honesty, seed pods begin to develop at the flower base, which mature into silvery, translucent discs.

What Tools are Necessary for Hand-Pollinating Annual Honesty?

Small Brush

A small, soft brush can be used to transfer pollen from the male flower to the female flower.

Ziplock Bags

Ziplock bags can be used to isolate the flower to prevent accidental pollination by insects.

Tweezers

Tweezers can be used to gently handle the flowers without causing any damage.

What is the Optimal Time for Hand-Pollinating Annual Honesty?

Hand-pollination for annual honesty is often best done in the early morning when the flowers have just opened. The ideal period in the plant's growth cycle is the commencement of flowering, typically in late spring or early summer.

Steps to Hand-Pollinate Annual Honesty

Step1: Cleaning

Wash your hands and clean all tools to avoid bringing in foreign pollen.

Step2: Isolation

Using ziplock bags, isolate the flowers you plan to hand pollinate. This will prevent unintentional cross-pollination by insects.

Step3: Gathering Pollen

Use a small brush to gently sweep over the stamen of the male flower to collect pollen. The stamen is usually located in the center of the flower and is surrounded by petals.

Step4: Transferring Pollen

Gently brush the pollen onto the stigma of the female flower. Like the stamen, the stigma is usually in the center of the flower but is more pointed and stick-like.

Step5: Reisolation

Once pollination has occurred, re-isolate the female flower using the ziplock bag for a few days to allow for fertilization.

Step6: Monitoring

Monitor the annual honesty plant for signs of successful pollination such as the growth of fruits or seeds.

Why Aren't There Fruits on Annual Honesty Despite the Presence of Flowers?

Lack of Pollinators

If annual honesty flowers aren't getting pollinated, introduce more pollinators to the area, such as bees and butterflies. Consider planting pollinator-friendly plants nearby.

Poor Weather Conditions

Poor weather can hinder pollination. If cold, wet weather coincides with annual honesty's flowering, consider using plastic coverings for protection and manually pollinate if necessary.

Poor Positioning

Annual honesty needs plenty of sunlight for good pollination. If the plant is in a shady spot, consider relocating it to a sunnier site.
