I've had Rocket City for more than 20 years. It's as carefree as any perennial I've ever known, as I have it planted along the foundation of the south-facing side of my house and it's flawless: it flowers without fail every single year.
Moreover, it's below a 2-story drop where the snow slides off the roof every winter and buries everything below under an average of four feet of snow and ice for five months. Yet every spring, it comes back as pristine and perfect as though nothing ever happened.
This daylily goes dormant, so zone 3 winters never faze it... and it's been through temps as low as -50 F. in the years I've had it. No rust, no pests, no problems ... just a splash of brilliant charm every summer and always blooms profusely. A definite winner!
