Hi mrsyarbie,
I too was a little disappointed when I first saw the landscape plants that we 'inherited'. I too was hoping for "tropical' flavor.
After some research I realized that here in central florida our growing zone is a bit cooler than I expected. We are on the north edge of zone 9. Tampa Bay is zone 10.
Many tropicals are borderline here, because of our winters.
That's not to say you can't try them, just that some varieties aren't reliable.
I was shocked to see holly.... and then I found out that many holly varieties are native to Florida!
So what you see here are the easiest and most reliable to get established for the climate. Young (small) plants grow and fill in faster with much less stress and needed attention than bigger ones will.
We have changed out a few plants and added a few that I have done research on. I really had to change my vision. Consider that at least for now you have something in place until you have the luxury of time to choose the perfect plants for the perfect spots.
They could have left us with bare pine straw, or given us all the exact same 5 or 6 bushes. I do see some variety from house to house as they are sold, so although it's not perfection to my artist's eye, it's a good beginning.
Welcome and much happiness in your new home!
