Origin in Africa - not used to frost
Originally the lobelia come from the southern parts of Africa. They are used to warmth there. They are not good at dealing with frost. Even a temperature of 0 ° C can make the difference between life and death. In short: Lobelia are not hardy in our latitudes.

In this country mostly annual
The most common species that is commercially available in this country is Lobelia erinus. This specimen, of which there are many cultivars, is annual. That means when winter comes this plant will die. You have to replant or sow them every year. But that's not a problem.
Sown, germinated, blossomed
Lobelia are fast-growing and bloom in summer, even if they were sown in spring. From January, the seeds can be grown at home - preferably under glass. They are light germs that turn out to be extremely germ-friendly. From mid-May the plants can go out and at the end of May / beginning of June they will already bloom.
Perennial Lobelia: They can be overwintered
So-called perennial lobelia are perennial. They become larger, have a stronger growth and can tolerate a little frost, but not for days. You shouldn't challenge them! These journeymen should rather be provided with winter protection or be quartered indoors in a frost-free place.
How does overwintering work outside and in a bucket?
Perennial lobelia, which can survive the winter outside in this country or in a cool room, are, for example, the following types:
- Lobelia cardinalis
- Lobelia sessilifolia
- Lobelia siphilitica
- Lobelia splendens
- Lobelia x gerardii (hybrid)
- Lobelia x speciosa (hybrid)
These lobelia should only be overwintered outside in warm regions such as wine-growing areas. They are cut down in autumn and covered with brushwood, leaves or fir branches in the root area. They can be overwintered in the bucket at a cool place between 5 and 10 ° C.
Tips
If you try to overwinter lobelia, you shouldn't forget to take care of them in winter too. You need to be supplied with water sparingly but regularly.
