Hello Benoit, Have patience. I bought some mature species of Gethyllis and they let me wait for two years. They are wintergrowers in northern Europe. I grow them by min. 13C and they grow and flowering well. I use led light for about 12 houres a day. Take care with water, wait for the leaves before watering. It is not possible to grow them outside in northern Europe, they will rot away in a week time. Peter den Bakker The Netherlands. ----- Original Message ----- From: "Leo A.
