This is a beautiful name and I wonder why it isn’t more popular in English speaking countries. I prefer the name with a single L but this spelling is fine.
To be honest, I'm very surprised that this name isn't more popular. It's similar to Lily and Lillian. And although I like those names, it would be nice to hear something new. I encourage parents to use this name more.
Personally, I like this better than "Lily/Lilly/Lillie/Lillian/Liliana". It is very modern and different - not to mention cute and pretty. I would definitely use this someday.
