Culture
The Schlumbergera are sensitive to the duration of the night. The floral buttons start to be formed and to develop as soon as the nights lengthen sufficiently, i.e. with the beginning of the autumn.One can obviously reproduce this phenomenon artificially by putting the plants at the darkness during certain numbers of hours, even if it still makes day; shifted flowerings are thus obtained and it is not rare to buy thus in the garden-centers of Schlumbergera which precisely flower at the time when one decided to sell them, any time in the year.
