Hi Ann: This is Kimberly from landscape-solutions-for-you. I would like to thank you for visiting the website and also for the compliment.
I had to smile this morning as it just so happens I put up a page today on the plant specimen Indian Hawthorn. You can find it in the variety of more plants for you section or on the landscape solutions blog.
A dwarf Indian Hawthorn would work very well in a planter. Radican Gardenia would also do well in a planter. It is a dwarf Gardenia. Some of the smaller versions of the Croton family would work. Take a look in the tropics section and see if there is any other plant that may work for you.
Thank you again for taking the time to visit my site and good luck to you. If you need any other plant or landscaping suggestions, please feel free to contact me at the website. If anyone else has some suggestions for Ann, please feel free to share it right here.
