Opinions on what to plant in a palm garden?
Hello community! We inherited a little palm "grove" on the side of our driveway. Contained in this grove is a Mexican fan palm, a banana, a foxtail (maybe?), and a sago, among others. We also had some green fountaingrass. Among all of the palms, are many ferns and some alliums. Today, we removed some of the overgrown fronds from the fan palm and the foxtail, plus we removed all of the fountaingrass since it's considered an invasive plant here apparently. So now we have a couple of issues:
1) The grove gets full sun. Now that we cut back the palms, all of the ferns are in full sun, and I'm guessing they probably won't do too well in our hot sun.
2) With the removal of the fountaingrass, we now have a 5 ft. x 4 ft. triangle of empty space.
I was thinking about planting some type of citrus (lemon?) since we get very nice sun and I've always wanted a lemon tree, but we're not sure how it would work with the palms. Anyone have any thoughts as to how, if at all, I can make it work? I currently have a semi-dwarf meyer lemon in a container sitting there simply because it gets the best sun on our property.
Also, should we remove the ferns, or just wait and see how they do? I don't want to waste the water on them if they're just going to die this summer.
Finally, any thoughts as to whether some color might look good here? I like all of the green, but maybe some sort of flowering plant might work here too?
I posted a pic so that anyone interested can see the empty space in the foreground (it's right next to our curb -- it's a pretty small space....) You can also see the ferns and the allium. BTW the distance from the sprinkler head in the foreground back to the start of the ferns is about 4 feet, and it's a triangular space.
And I apologize that the pic is sideways!
I'll take any and all advice!
