Thank you for a good laugh and I am impressed by your tenacity. It must be human nature to want to grow the things that we rarely see around us. You have made me feel much better about all of the things that I cannot grow here in South Australia. Adelaide, South Australia calls itself the rose capital because roses grow so well here. The general consensus is that you can't kill 'em with an axe! The photos you have seen may have been taken here but even so I nearly lost some of mine last year in a 14 day heatwave of over 95F ending in a 110F day. The roses growing near a metal fence cooked all through their thick branches and are now trying to reshoot from ground level. As you can imagine many of the lovely lush things that you can grow in Summer would have no hope here unless they are in shadehouses with microsprays (currently banned because of water restrictions).
I have visited the US several times and am amazed at Hibiscus and other shrubs that we grow for 20 or 30 years, being described as annual shrubs.
Glory in your tulips, trout lilies, liliums and fuchsias, which we find just as difficult to grow as you do roses.
