Almost a month gone by without a reply, so I guess I'll share my story ^^
I bought my bulbs (three of them) in a local grocery store, I just couldn't resist lol. I planted them up a few days later in some ordinary potting compost (an inch below the soil) and stored them in my basement where it was around 12°. I thought to slow them down in their growth until the weather was warmer, but then moved them upstairs to my living room thinking they were just a little too cold there. After a week later they came up and since we've had really warm and sunny spring weather, I dragged them outside every day and back indoors every evening, just in case a frost spill occurs.
They really seemed to enjoy the full outdoor sun 'cause the last week they've really gone off! :D
