Ken and Maurice, what great botany lessons, thank you both! Sounds like I really should be thinning whoever I do have - they do get to be a really large mounded clumps quite quickly, although that is a bit of a challenge for me to do (the root system can be a bit daunting). For my personal records, I will continue to call her Stella, she's been with me for over 15 years. I'll try to get better photos this season, can't believe I wasn't able to find a better portrait or even a long shot showing the growth pattern.
