Laurie, are they root-hardy where you are also? As soon as there's a frost here, everything above ground will be zapped, but will grow back when it warms up again the next spring/summer. The biggest herbaceous perennial I've ever had in my landscape.
Anne, I was hoping to get a better chance to sniff a bloom before answering that but I never did. They were way above my head & then I had to move that plant to get my new greenhouse into its' final spot. That caused some wilting & it may not have a chance to make more before 1st frost, will have to keep an eye on plant & weather. The plain white ones I smelled were too similar to Lemon Pledge for my taste, but I'm told these peachy ones have a diff scent.
Colleen, the banana thing is just like it sounds, scratch a little dirt back somewhere near the base of the plant, place whole banana or, more often for me, just the peels, then cover again. When it's really hot during summer I don't usually bother covering. Within a few hours, it will be shriveled/melted, looking like part of the mulch. The nutrients in the banana are the ones needed to encourage blooms on roses, and apparently also on Brugs, assuming it's the right time of year & conditions are otherwise not prohibitive of blooming and all that's missing is some nutrients in the soil.
