Description
It is a simple plant of culture, it is even sometimes invasive. She prefers large pots.
It is at home in a cold greenhouse. It tolerates small frosts, but it is taking a risk for the plant.
The substratum must be aerated enough (mixture 2/3 of blond peat and 1/3 of perlite/sand (not calcareous)).
The flowers are very beautiful and the trigger system when you touch them is quite fascinating.
