| Dahlia imperialis in Tokyo Botanic Garden, it was my first encounter with this fantastic plants. Since then I started an effort to grow this plant first in Vienna then in Sweden | |

|
| A Dahlia Imperialis at the Bergianska Botanic Garden in Stockholm, I will ask them if they got flowers. | |
| 2017 | The first attempt to grow it in Vienna from Rhizomes was promising, The plants reached 2 - 2.5 meters but the as the winter was approaching the plant started to wither and so much expected blossom never occurred |
| 2019 | The next attempt was conducted in Sweden, again the plant was growing vigorously and as the fall was approaching i took the Dahlia indoors provided with extensive artificial light but the plant started to wither, lose leaves again without the flowering. (the temperature was around 15 degrees. |
| 2020 | The some of the Dahlias survived the winter and i started to grow it outside again. The growth was reduced but i succeeded to take cuts from the old stems using layering. By the end of 2020 no flower occurred. The old plants are not in a good conditions and i hope they have produced rhizomes |
