  1. I love your website, and thoroughly enjoy getting all of your newsletters. I can sit for hours reading them. I am never sure
    just what will work for me here in Southern Ontario (Between Toronto and London) when looking at your ideas.
    What zone are you in? Have made some of your recopies and going to do some stepping stones.
    Keep up the great work.
    PS I do not have a green thumb.

    • Hi Florence, Thank you so much for the kind words!! I’m in Zone 7B. You should find lots of info that will work for you, I try to write articles that can be adapted to many zones, but of course, you should always adjust plants etc for your zone.

  2. The blue cascading flowers you show in this article are gorgeous. I’m in Dallas (TX) so I’m guessing I can grow them here.
    Would you PLEASE provide the name of this plant so I can see if they are available in our area.
    Second inquiry.

    • Hi Larry, not sure which ones you are referring to. I don’t see blue flowers or a first inquiry.

      • My color sense is not the best. Maybe they are purple, but they are cascading over a wall.

    • Larry, I wonder if it’s the bluish/purple flowers you see which I believe might be the Lavender flowers?

  3. Hi Stephanie!

    I live in Tennessee and it can get very hot. I get full hot sun in the front of my house. I need to know what perennials would be good? I’m having a hard time growing plants and they may get diseases.

  4. Oh my gosh I enjoy your site so much, yes it is so my therapy and happy place.
    enjoy your visit with your sister
