You have the perfect opportunity to plant a hill of native species that thrive in dry soils and will attract birds. A variety of sumacs, certain dry-tolerant dogwoods, eastern red cedars, black chokeberries, ninebark. Many of these shrubs colonize well. Over time they will form a thicket. You can also plant some tap-rooted dry tolerant trees for a natural succession. At first it will require maintenance to keep the berm from becoming weedy. You'll also have to water for a time until plants gets established.

I suggest you post a picture(s) on the thread that shows the overall berm as it is.

Here's a photo of our berm/island;

I have a hard time relating to some Florida landscapes and I have been there many times.

This makes me think we should have a thread where people post photos of a vignette in their yard and have people guess where they live just based on that. Botann's photos tend to loudly suggest PNW and Susieq07's photos shout Gulf of Mexico.

I would know suzieq07's instantly from past shared photos - everything has a blue and white color scheme. :-)

I'm so positive, I had to say it twice!

If your home looked like this what colors would you use, all flowers outside my home are pink, white, blue or lavender, no colors that clash but only enhance.. very picky that way!
See how pretty pink looks with my teal blue,Yes,I am on the Gulf side of FL. in pradise...

Brighterday, the original poster, has her gardening zone listed as "4a". No way is that in Florida!

Maybe she meant her post was a "foray"...? (an attack or incursion into enemy territory)
