that's too bad about the Mexican feather grass. Maybe they meant (and why they use these trems I do not know) it was a "tender perennial"? I only find that confusing! The best thing you can do is be aware of what hardiness zone you think you are supposed to be in, and then read the plant labels for the "recommended" hardiness zone, try to determine where the plants grow normally, then put them where you think they might do best. Operative word in that sentence seems to be "think", doesn't it (I just read it over!). In many cities, especially, there are variations due to the micro-climates in the city; as well, breeders are coming up with more hardy varieties of plants all the time. I love Lois Hole's approach -- she says to use the hardiness zones as a rough guide, and then, basically, do what you want! The plant may live and it may not, but all of your garden should be an experiment. Mine is...

is native to Texas and is listed as a zone 7-10. London is only Zone 6, so, no, it is not perennial in your area.
Look on google for "plant hardiness zones in Canada" and you will come to the Natural Resources Canada Website.

As for your black-eyed susans, who knows. If one has been up for some time and the otehrs are not showing themselves and they are in the same place, then I would say they are done.
