Looks like E. Afterglow to me:). I have a hard time growing Sunburst. Yours is beautiful how much sun does your plant get?

Thanks! Not sure of the number of hours, maybe 6. But it does not get the late afternoon sun.

Edited to add: Since you asked I paid more attention to it today. It's actually in full sun. Gentle now, but harsher when summer arrives.

very nice. and about sunburst-sigh. mine not only refuse to flourish but obstinately insist on dying.
