Hi, you say it has great soil, care, etc., but don't describe what you mean by that... it would help a lot to know where it lives, under what conditions, what you've done to it, etc. etc. And BTW, there's only one 'T' in it... it's pronounced Koh Toh (toe) Nee Aster, emphasis on the Toh. They should change the name so people can say it!
