To sow: From March to May in loose, fine-crumb flower bed soil, at a good distance from each other and half a centimetre deep. At 15 to 20 degrees Celsius, the seed will germinate within three to four weeks. Later, thin out the young plants so that there is a 25 cm distance between each one. They will flower for the first time in the year after sowing in May/June.
Tip: Cut off the flower stems with dead flowers on, and the plants will flower again in autumn. However, leave the ripened seed capsules on the plant in case the columbines can self-sow from their location.
