Honesty is grown for its flowers and papery seed pods. Check the seed label and local season before choosing a container or sowing date.
Grow for the whole cycle
Honesty, usually Lunaria annua, is valued for its flowers and the papery seed cases that follow. Many plants make a leafy rosette before flowering in their next season. A first-year plant without flowers is not automatically failing.
Sow where seedlings can develop
Use a prepared patch or suitable seed container with even moisture during germination. Thin crowded seedlings so leaves and roots have room. Keep the label until plants are established; young rosettes can be mistaken for unwanted seedlings.
Choose an ordinary garden position
A position with light or partial shade and soil that drains after rain is usually more practical than a hot indoor windowsill. Water young plants during dry spells without leaving the ground saturated around their stems.
Decide whether to keep the pods
Leave some flowering stems if the seed cases are wanted for display. If self-sowing is becoming excessive, remove others before the seeds disperse. Collect mature material thoughtfully rather than scattering seed beyond the area intended for the plant.
