A representative of the Asteraceae family is the Bornholm daisy. It impresses with its pretty flowers, which are arranged in large numbers on its stems. Although it is only an annual, it can be cultivated for several years.
Can the Bornholm daisy be grown as a perennial?
The Bornholm daisy is actually an annual, but can be cultivated for several years by protecting it from frost and overwintering indoors at 5 to 15 °C in winter. During wintering, ventilate the room regularly, water sparingly and do not fertilize.
An annual plant
The Bornholm daisy grows into a small perennial within a few weeks. If you sow them in March, you can admire the flowers in May. After the flowering period, the plant goes to rest. As soon as the first severe frost stalks in, it freezes. It is therefore considered an annual.
Cultivation for several years is possible
It's the frost that's bad for this plant. Without it, many varieties of Bornholm daisy would be perennial. Within a few years the plant can develop into a nice large bush. Over the years it gains more branches and can subsequently produce a higher number of flowers.
Extremely sensitive to frost
5 °C is the minimum. The thermometer display must not drop any further. This means that the Bornholm daisy is considered sensitive to frost. At best it could survive the winter outside in very mild locations and with a good layer of leaves and brushwood. Otherwise, there is no point in overwintering outside
Origin in Africa
The reason for its poor winter hardiness is its origin in Africa. There the Bornholmer Marguerite, a dwarf shrub, is never exposed to frost. Therefore, it could not adapt to the frost that occurs every winter in this country.
How to overwinter the Bornholm daisy
Have you decided to spend the winter? Then you should know the following points:
- Dig up bedding plants and put them in a pot
- It's best to cut back first
- place in the house in a bright, air-conditioned room at 5 to 15 °C
- water little
- do not fertilize
- Air the room regularly
Potted plants from the balcony or terrace should also be put in. This should ideally happen in mid-October. If the Bornholm marguerite has survived the winter well cared for, it can slowly be used to direct sunlight again from April onwards.
Tip
If you can't find a suitable place to spend the winter, you don't need to worry. The Bornholm daisy can be easily sown again in spring or bought cheaply as a young plant.
