Frilly - I've come to the conclusion that I'm not as patient as I should be and 2 to 3 years of babying a plant isn't for me. Makes me think I can live without it. I'll baby my vegetables for the summer but perennials not so much.
Jersey - I lost 'Mrs. Moon' as have other experienced midwest gardeners. I did lose 'David Ward' twice and gave up on it. Pretty flower color though. I've had 'British Sterling' for 20 years and have been happy with the silver. 'Majeste' is also a good one. I haven't looked at any recent introductions.
Rose - Heucheras are another plant that can be iffy if it doesn't have the right parentage for midwestern summers. I love 'Lime Ricky' and it survives the winter but fades fast once the summer heat hits. I've lost that one twice because I didn't know any better. Unless I've done a little research, I won't pay $15+ for a new Heuchera.
You are right about the 'Ghost' fern. It is very pretty but it has taken it's sweet time becoming established here. Because I'm on city water and my back shade garden is 150 ft long and roughly 20 ft deep, I try to avoid watering as much as possible. Mulching with fall leaves has been a real saver.
