I'm in the PNW in Springcolor's area. She's my gardening mentor.
My snow angel is still happy. I think I've had her about 4 summers. When it started looking poorly this past spring, I divided it to see if I could save it. Now my new ones and the mother plant are thriving. I put the new ones where they get more sun than the mother plant which I left where it was.
Marmalade had lots of rust and looked sad so I separated that and moved the new one to a sunnier place. Now both plants are thriving. I've had Maramalade for 3 or 4 years. I'm wondering if they just get tired after I've had them a few years and just need to be divided.
Creme Brulee and Caramel have never done well for me. I've even tried them in other areas. They just don't thrive like. my others ones do. I still have a small Caramel that barely grew this summer. I don't think separating and dividing them would help plus they've never gotten large enough divide
