Hello Benoit, Did you buy the bulbs from north of the equator or south? Bulbs from north of the equator should grow now. Bulbs from south of the equator will sleep for 3-4 months before they grow. Where do you live in France? Gethyllis grow outside if the temperature is above 0-5 Centigrade in the day and above -8 to -5 C at night. A greenhouse with 8C minimum in winter might be too hot. My Gethyllis are sprouting now in Phoenix. They are outside. Nights are 3-5C and will soon be a little colder. Days are 10-18C. Leo Martin Phoenix Arizona USA -- Leo Martin Phoenix Arizona USA
