    Wow, I didn’t realise there were so many trailing flowers. I’ve tried growing trailing petunias in my hanging baskets before and I didn’t have much success. I’m not sure what I did wrong. Which of these flowers would be the easiest to grow for someone who is not naturally gifted at gardening?

  2. Trish Veltman

    Nice post – some gorgeous plants in this list. We had red and white petunias this spring / summer and they’ve been stunning – still blooming but the foliage is looking a bit dry and straggly now we’re coming up to autumn here. Might have to replace with some pansies for the winter.

  3. Doris Jean

    These flowers are gorgeous and I’m always amazed by how many types of flowers there are. Such an informative and detailed post.

    I have always loved the look of African Daisies, especially in that deep purple shade. I have been considering putting together some window boxes for our house this year and if I do, they are definitely going to be part of that. Thank you for sharing this list – now I have a few other options for flowers that I could include in those.

  5. Kathrin Spinnler

    My mother has three lovely, large hanging baskets and keeps several of these plants. It’s always a pleasure to see them when I visit her.

    I am partial to petunias because they are so beautiful and pretty easy to grow in my area. I need to plant some since spring is right around the corner and I am so ready this year!

    I plan on planting petunias in our window boxes this season! Can’t wait till it’s warm enough here.
