In 2007 I decided to leave it in the garden for winter. The December was relatively warm and it woke up in the end of January. |
 |
So it looked in the spring of 2008, it had many leaves, but it did not bloom. |

 |
Next winter it also stayed in the ground. This photo shows how it looked after -25°C (-16°F) frost in January 2009. It survived that winter and put new leaves next spring. |
 |
Usually it wakes up in autumn, but in some years it started to grow in March. |

9 years of cultivation and it has never bloomed so far. |
