Hi Zuzu,
I also dislike the cold. Though by any standard other than a Californian, what we have here is not considered cold. It's wonderful that you still have so much color in your yard. I also discovered Nerine a few years ago for fall/winter color. But, mines never seem to mulitply. I plant 5 bulbs - I get 5 blooming plants the next year.....sometimes less, but never more. Your patch looks so full and healthy. Do your nerine bulbs multiply?
